filter lines from a text file by searching for words

, split columns and replace text with a free open source tool for the Windows command line, Mac OS X Terminal, Linux shell or Raspberry Pi.
- download the free Swiss File Knife Base from Sourceforge.
- open the Windows CMD command line, Mac OS X Terminal or Linux shell.
- OS X : type mv sfk-mac-64.exe sfk and chmod +x sfk then ./sfk
- Linux: type mv sfk-linux-64.exe sfk    and chmod +x sfk then ./sfk
  OS X and Linux syntax may differ, check the help within the tool.
sfk filter [fileOrDir] -selectoption(s) -processoption(s)
sfk filt -selectoption(s) -processoption(s) -dir mydir -file .ext1 .ext2
sfk filter [-memlimit=n] -write inoutfile -replacepattern(s)
sfk ofilter in.xlsx -+pattern

filter and change text lines, from standard input, or from file(s).
input lines may have a maximum length of 4000 characters.

use ofilter to read plain text content from a single office
file like .docx .xls .ods ('sfk help office' for more).

line selection options
   -+pat1 -+pat2         include lines containing pat1 OR  pat2
   -and+pat1 -and+pat2   include lines containing pat1 AND pat2
                         in any order.
   "-+pat1*pat2"         include lines containing pat1 AND pat2
                         in the given order.
   -ls+pat1              include lines starting with pat1
   -le+pat1 -le+pat2     include lines ending   with pat1 OR pat2
   "-ls+pat1*pat2"       include starting  pat1 and having pat2
   -!pat1 -!pat2         exclude lines containing pat1 OR  pat2
   -ls!pat1              exclude lines starting with pat1
   -le!pat1 -le!pat2     exclude lines ending with pat1 or pat2
   -no-empty-lines       exclude empty lines
   -no-blank-lines       exclude lines containing just whitespaces
   -inc[lude] p1 to p2   include only lines within blocks surrounded by
                         boundary lines containing patterns p1 or p2
   -inc-      p1 to p2   same, but exclude boundary lines on output
   -cut[-]    p1 to p2   remove block of lines from p1 until p2
   -inc[-]    "*" to p1  include all from text start until marker
   -cut[-]    p1 to "*"  cut all from marker line until end of text
   -head=n               read only first n lines of text files
   -tail=n               read only last n lines of text files
                         (up to a limit of 100000 bytes from file end)
   -line=n               read only nth line from input
   -skipfirst=n          skip first n lines. warns on hard wrap.
   -force                accept hard wrapped lines with -skipfirst
   -nocheck              with inc, cut: ignore endings without a start
   -addmark txt          with inc, cut: insert txt after every block
   -context=n            select n lines of context around hit lines
   -precon=5:blue        select context before or after hit lines,
   -postcon=5:cyan:---   in blue or cyan, with separator "---".
   -unique [-case]       if same line occurs twice, keep only first.
                         default is case insensitive text comparison.
   -global-unique        when filtering multiple files in one command,
      then -unique applies to lines in the same file, and -global-unique
      applies across all files. this will cache the text of all files in
      memory and may not be used with very large files.
   -keep pattern         after -unique: make an exception for lines
      containing the given pattern, and keep them even if redundant.
   -keep-empty, -keep-blank always keep empty or whitespace lines.

text processing options
   applied after line selection options only.
   -rep[lace] _src_dest_
      replace string src by dest. first character is separator character (e.g. _).
      src is case-insensitive. to select case-sensitive search, say -case.
   -lsrep[lace], -lerep[lace]
      same as -replace, but replaces only once at line start or line end.
   -high[light] color pattern : highlight matching parts within lines.
      color: red = dark red, Red = bright red, green, blue,
             yellow, cyan, magenta, default.
      pattern: e.g. "GET * HTTP/"
      type "sfk help colors" for more about colors.
   -lshigh[light], -lehigh[light]
      same as -highlight, but only at line start or line end.
   -sep[arate] "; " -form "$col1 mytext $[-0n.nq]col2 ..."
      break every line into columns separated by any character listed after -sep,
      then reformat the text according to a user-defined mask similar to printf.
      when leaving out -sep, the whole line is packed into column 1. if -spat was
      specified, then -form also supports slash patterns like \t.

      google for "printf syntax" to get more details. example:
   -form "$40col1 $-3.5col2 $05qline $(10.10qcount+1000)"
      reformat column 1 as right-ordered with at least 40 chars, column 2 left-
      ordered with at least 3 and a maximum of 5 chars, then add the input line
      number, "q"uoted, right justified with 5 digits, prefixed by zeros,
      then the output line number plus 1000 within quotes. NOTE: some examples
      may not work in an sfk script, see section "common errors" below.
      adding values so far only works with (q)line and (q)count.
   -tabform "$col1 mytext ..."
      split and reformat columns of tab separated csv data.
   -stabform "$col3\t$col2\t$col1"
      reorder three tab separated columns, creating tabbed output
      using 's'lash patterns like \t
   -utabform "#col1 mytext ..."
      same as -tabform but using unix style syntax, to create scripts
      that run without changes on Windows and Linux.
   -uform "#40col1 #-3.5col2 #05qline"
      same as -form but using unix style syntax. short for filter -upat.
   -trim  removes blanks and tab characters at line start and end.
          use -ltrim or -rtrim to trim line start or end only.
   -blocksep " " = treat blocks of whitespace as single whitespace separator.
   -join[lines] join output lines, do not print linefeeds.
   -wrap[=n]    wrap output lines near console width [or at column n].
                set SFK_CONFIG=columns:n to define or override the console width.
   -toiso[=c]   converts UTF-8 text to ISO-8859-1. some chars beyond
                the 8 bit code range will be reduced to something similar, but
                most of them are changed to a dot '.', or character c.
   -toutf       converts ISO-8859-1 text to UTF-8. if this is done with UTF-8
                input text then existing UTF-8 sequences will be destroyed!
   -tolower     or -toupper convers a-z to lower- or uppercase.

conditional text processing
   -[ls/le]where pattern -replace | -highlight | -sep ... -form
       replace, highlight or reformat lines matching the given pattern.
       all lines that do not match the pattern stay unchanged.
   -within pattern -replace _from_to_
       replace text in a part of the line matching the given pattern.
       the rest of the line text stays unchanged.

pattern support
   wildcards * and ? are active by default. add -lit[eral] to disable.
   slash patterns are NOT active by default. add -spat to use \t \q etc.
   if you need the wildcard * but ALSO want to find/replace '*' characters:
   add -spat, then specify \* or \? to find/replace '*' or '?' characters.
   instead of typing "sfk filter -spat -rep" all the time, you may use the
   short form "sfk filt -srep". the same applies for -(s)sep, -(s)form etc.

unified syntax
   since sfk 1.5.4 you can also use -: -ls: -le: under windows.
   filter ... -uform or filter -upat ... -form uses # instead of $.

sfk variables versus -tabform
   with -upat under windows, of sfk for linux, both filter -tabform
   and sfk variables use the syntax #(name) to insert values.
   to solve this, variable parsing is not strict and may keep
   undefined variable names as is.

quoted multi line parameters are supported in scripts
   using full trim. type "sfk script" for details.

further options
   -case           compare case sensitive. default is case insensitive.
                   for further options see: sfk help nocase
   -lit[eral]      treat wildcards * and ? as normal chars (read more above).
   -arc            XE: include content of .zip .jar .tar etc. archives
                       as deep as possible, including nested archives.
                   XD: demo will read first 1000 bytes of each entry.
   -qarc           quick read top level archives but not nested ones.
   -verbose        show names of all files which are currently scanned.
                   with wfilter: tell current proxy settings, if any.
   -write          do not print output to console but overwrite input file(s).
                   only files with actual text changes will be rewritten.
                   this function may be used only with plain ASCII files, not with
                   binaries like .doc, .xls. see also "sfk replace".
   -write -to msk  do not overwrite input files, but save according to mask msk,
                   e.g. tmp\$file . saves only changed files. say -writeall
                   to write all files, including those without changes.
   -memlimit=mb    when using -write, output is cached in memory, which is limited
                   to 300 mb. use this option to extend, e.g. -memlimit=400
   -yes            -write simulates by default. add -yes to really write changes.
   -snap           detect snapfiles and list subfile names having text matches.
   -snapwithnames  same as -snap, but include subfile names in filtering.
   -nofile[names]  do not list filenames, do not indent text lines.
   -subnames       with ofilter: insert .xlsx sheet subfile names.
   -count, -cnt    preceed all result lines by output line counter
   -lnum           preceed all result lines by input  line number
   -hidden         include hidden and system files.
   -noinfo         do not warn on line selection combined with -write.
   -noop \"        no operation, take the \" parameter but do nothing.
                   may help if your (windows) shell miscounts quotations.
   -hitfiles       if another command follows (e.g. +run or +ffilter),
                   pass a list of files containing at least one hit.
   -nocconv        disable umlaut and accent character conversions during
                   output to console. "sfk help opt" for details.
   -justrc         print no output, just set return code on matching lines.
   -upat           unix style syntax with -form, using # instead of $
   -timeout=n      with wfilt: wait up to n msec for web data.

list of possible input sources
   from stdin:                 type x.txt | sfk filter -+pattern
   from single input file:     sfk filter x.txt -+pattern
   text from chained command:  sfk list mydir .txt +filter -+pattern
   from many files, directly:  sfk filter -+pattern -dir mydir -file .txt
   from many files, by chain:  sfk list mydir .txt +filefilter -+pattern
   in general, whenever you need to make sure that file contents (not the
   file names) are processed, prefer to say "filefilter" or "ffilt".

web access support
   searching the word "html" in an http URL can be done like:
   sfk filter -+html
   sfk filter http://.100/ -+html
   sfk wfilt .100 -+html
   sfk web .100 +filt -+html

return codes for batch files
   0   normal execution, no matching lines found.
   1   normal execution,    matching lines found.
       with -write: returns rc 1 only if any changes were written.
  >1   major error occurred. see "sfk help opt" for error handling options.

common errors
   when using filter -form within sfk scripts, expressions like $10.10col1
   may collide with script parameters $1 $2 $3. to solve this, use brackets
   like $(10.10col1), or "sfk label ... -prefix=%", or -uform.

   sfk ... +getcol n   get column n of whitespace separated text.
                       same as +filter -blocksep " " -form $coln
   sfk ... +tabcol n   get column n of tab separated text.
                       same as +filter -stabform $coln

beware of Shell Command Characters.
   to find or replace text containing spaces or special characters like <>|!&?*
   you must add quotes "" around parameters or the shell will destroy your command.
   it splits the command into parts and gives SFK only one part, causing errors.
   therefore -replace _ _&nbsp;_ must be written like: -replace "_ _&nbsp;_"
   within a .bat or .cmd file the percent % must be escaped like %% even
   within quoted strings: sfk echo -spat "percent %% is a percent \x25"

web reference

more in the SFK Book
   the SFK Book contains a 60 page tutorial, including
   long filter examples with input, command and output.
   type "sfk book" for details.

   anyprog | sfk filter -+error: -!warning
      run command anyprog, filter output for error messages, remove warning messages.
   sfk filter result.txt -rep "_\_/_" -rep "xC:/xD:/x"
      read result.txt, turn all \ slashes into /, and C:/ expressions to D:/
      the quotes "" are optional here, and just added for safety.
   sfk filter index.html -rep "_<u>_<b>_" -rep "_</u>_</b>_" -write
      replace underlining by bold in an HTML text. quotes "" are strictly
      required here, otherwise the shell environment would split the command
      at the < and > characters. add option -yes to really rewrite the file.
   sfk filter export.csv -sep ";" -format "title: $(-40col2) remark: $(-60col5)"
      reformat comma-separated data, exported from spreadsheet, as ascii text.
   sfk stat . +filter -blocksep " " -format "$(4col1) mb in folder: $(col5)"
      reformats output of the stat command. when using this in an sfk script
      round brackets () are required to avoid parameter name collision.
   sfk filter mycsv.txt >out.txt -spat -rep _\"__ -rep _\t__ 
    -rep "_;_\"\t\"_" -form "$qcol1"
      read semicolon-separated spreadsheet data mycsv, strip all double colons
      and tab characters from data fields. replace field separator ";" by TAB,
      and surround fields by double colon. -form without -sep means "pack the whole
      line into $col1", allowing -form to add quotes at start and end of each line.
   sfk filter logs\access.log "-+GET * 404"
      list all lines from access.log containing a phrase with GET and 404.
   sfk filter log.txt "-ls!??.??.???? ??:??:?? * *"
      excludes lines from log.txt starting with a date, and having two more words,
      like "20.05.2007 07:23:09 org.whatever.server main"
   cd | sfk run -idirs "sfk filt tpl.conf >httpd.conf -rep _AbsWorkDir_$path_"
      create httpd.conf from tpl.conf, replacing the word "AbsWorkDir" by the path
      from which the command is run. note we can NOT use -spat in this case, as
      a pathname like C:\temp would produce garbage (contains slash pattern "\t").
   sfk filter in.txt -spat -sep "\t" -rep _\q__ -form "INSERT INTO MYDOCS (DOC_ID,
    DESCRIPTION) VALUES ('TestDoc$03line','$col2');"
      this example (typed in one line) creates a list of SQL statements, using tab-
      separated, quoted input data, and using the input line number for document ids.
      the -rep _\q__ means the same as -rep _\"__ - it strips quotes from the input,
      but using \q is safer then \" as it doesn't let the shell miscount quotes.
   sfk list documents .txt +filter -+big*foo -+wide*foo
      from all .txt files in documents, filter the filenames (NOT the file contents)
      for big*foo OR wide*foo.
   sfk list documents .txt +filefilter -+big*foo -+wide*foo
      from all .txt files in documents, filter the file contents (NOT the names)
      for text lines containing big*foo OR wide*foo.
   sfk list logfiles .txt +filefilter -global-unique +tofile mixedlog.txt
      join all .txt files from logfiles into one output file mixedlog.txt,
      dropping all redundant text lines. works only if logfile records are
      prefixed by a unique record ID, and if overall text data is less than
      available memory, because all data is cached during processing.
   sfk list logfiles .txt +ffilter -global-unique -write -to mytmp\$file
   sfk snapto=mixedlog.txt mytmp
      same as above in two commands, using temporary files to allow more data.
   bin\runserver.bat 2>&1 | sfk filter -+exception
      filter standard output AND error stream ("2>") for exceptions
   sfk filter result.txt -+error -justrc
   IF %ERRORLEVEL%==1 GOTO foundError
      in a batchfile: jump to label foundError if text "error" was found
      within file result.txt. with -justrc no output is printed to terminal.
   sfk filt log.txt -high cyan "*.*.*(*.java:*)" -high green "sql select *"
      dump log.txt, listing java stack traces in cyan, and sql selects in green.
   sfk filt x.html -where "000099" -rep "_<font*000099*>_<b>_" -rep "_</font>_</b>_"
      replaces html <font> commands by <b>, but only in lines with "000099" (=blue).
   sfk filt foo.cpp -cut "ifdef barmode" to "endif // barmode"
      strip blocks of lines from foo.cpp, surrounded by the given patterns.
   sfk fromclip +filt -srep "_\\_\\\\_" -srep "_\q_\\\q_" -sform "\q$col1\\n\q"
      convert text from clipboard to source code, e.g. change
         the "tab character" is written like \t
      to a C++ or Java string literal like
         "the \"tab character\" is written like \\t\n"
   sfk filt csv.txt -spat -within "\q*\q" -rep _,_\x01_ -rep _,_\t_ -rep _\x01_,_
      change separators in comma separated data from comma to tab, also taking
      care of quotes, by replacing in-quote commas by a placeholder (\x01).
      if the data contains escaped quotes like "" then further prefiltering
      can be necessary, like removing those quotes by -sreplace _\q\q__
   sfk filt mysrc.cpp "-+fopen(" -postcontext=3:blue:----- +view
      filter source file "mysrc.cpp" for fopen calls, and list the following
      three lines (post context) of every call, separating outputs by -----
      and showing the whole result in Depeche View ("sfk view" for more).
   sfk filter -tail=10 -dir proj -file .cpp
      show last 10 lines of every .cpp file within folder proj.
   sfk select mydir .txt +ffilter -head=10 -+mypat
      search first 10 lines of every .txt file of mydir for pattern mypat.
      notice the ffilter to read file contents, not just filenames.
   sfk filt mydir -+foo +copy out
      copy all files from mydir containing a pattern to out
   sfk filt -noname mydir -+foo +texttofilenames +copy out
      copy from filenames found in text files. needs option
      -noname to avoid filename headers and indention.
see also:

   sfk replace    - find and replace text of equal length. works also 
                    with binary files, and allows, for example, to replace
                    (CR)LF line endings completely by a different string.

   sfk find       - find text in text and binary files.

sfk is a free open-source tool, running instantly without installation efforts. no DLL's,
no registry changes - just get sfk.exe from the zip package and use it (binaries for
windows, linux and mac are included).
