The current general sfk options.

sfk general options reference:

Please note: some of these options are supported only by some commands.

-var       insert SFK variables by using #(varname). type this
           option directly after "sfk" to use it globally with all
           commands in a chain or script. to print "#(" literally
           then escape it like ##(
-upat      unix compatible file or text selection and patterns.
           allows to use -subdir :/tmp instead of !\tmp, filter -:foo
           instead of -!foo and run "#file" instead of "$file",
           to create unified .sh batch files for Windows and Linux.
-upat2     same as -upat but also support wildcard % instead of *
           you may also set this by an environment variable like:
           set SFK_CONFIG=upat2
-nosub     or -norec does not include subdirectories (subfolders).
           processing of subdirs is DEFAULT with most commands,
           therefore you must specify -nosub to switch it off.
-withsub   include subdirs. is DEFAULT with most commands.
-verbose   print additional infos while running a command.
           helpful if a command doesn't work as expected.
           only some commands support -verbose. try also -verbose=2.
-nofollow  or -nofo does not follow symbolic directory links.
           this option may NOT work with older Linux versions,
           esp. those needing the "lib5" binary version of sfk.
-quiet     reduce output on some commands. e.g. the find command will
           not display the "scan" status info while searching files.
-quiet=2   reduce output even more on some commands.
-memcheck  check memory list at the end of every command
           to detect overwrites. reduces performance.
-debug     print extra program flow infos to track errors.
           also activates -memcheck under Windows.
-nohead    no not list header/trailer info on some commands: the run cmd
           will not tell "simulating" even if it's in simulation mode.
-case      activate case sensitive text comparison with some commands.
           most text processing commands are case-insensitive by default.
           filename comparison is always case insensitive.
-hidden    include hidden and system files.
-nohidden  exclude hidden and system files.
-yes       fully execute the command. some commands like "run" are
           running in simulation mode by default, to avoid damage to your
           files, as long as you're unsure which files and dirs to select.
           as soon as you add -yes, however, everything is fully executed.
-minsize=s select only files >= size, like 10b or 100k
-maxsize=s select only files <= size, like 10m or 4g
           b=bytes k=kbytes m=megabytes g=gigabytes=10^9 bytes
           K=2^10 bytes M=2^20 bytes G=2^30 bytes
-weblimit=n  change web access download limit to n mbytes,
           with functions like sfk web, filter, xex. default is 10 mb.
           you may also set SFK_CONFIG=weblimit:20
-webtimeout=n  web access timeout in msec. default is 10000.
           you may also set SFK_CONFIG=webtimeout:3000
-headers   print http headers with commands accessing the web.
-textfiles process only text files, no binaries. -text is the same,
           but this may interfere with some command's local -text option.
           text/binary detection only checks the file's first 4 kbytes.
-binfiles  process only binary files. -bin is the same, but this may
           interfere with some command's local -bin option.
-umlauts   with binary-to-text conversion, include german characters.
-nocol     disable all colored output. important if your shell has
           a background color incompatible to the default color scheme,
           or (under linux) if the sfk output text must be processed
           further through pipelining, and needs to be stripped from
           the color escape sequences.
-col       switch on colored output. "sfk help colors" for more.
-html      dump sfk help text (color control) in html format.
           -html must be typed directly after "sfk".
-htmlpage  the same, but include a header to view it in a browser.
-sincedir  or -sincedif/add/chg: compare directory tree against
           a reference tree, process only changed or added files.
           see "sfk list" for details.
-tracesel  give verbose infos why directories and files have been
           selected or excluded. -tracedirs lists only directories,
           -tracefiles lists only files.
-since     process only files changed on or after the supplied
           date/timestamp. "sfk list" for details.
-before    process only files changed before that date/timestamp.
-flist fn  or "-fl fn" reads list of filenames from file fn.
-spat      activates interpretation of slash patterns:
           \t=TAB \q=" \r=CR \n=LF \\=\ \xnn=any char w/hex code nn
           with some commands like replace, filter -form and -replace.
-literal   or -lit disables interpretation of wildcards * and ?
           and slash patterns, if they were activated previously.
-nospat    disables only slash patterns.
-nocconv   when printing output to the windows console, sfk tries
           to convert umlaut and accent characters to display them
           correctly with codepage 850. set -nocconv to disable this.
           whenever output is redirected to file, no conversion is done.
-cconv     force codepage conversions: if command output is redirected
           to a file, codepage conversion is disabled by default.
           use this option to activate, e.g. when post-processing
           sfk run output which produced filename lists.
-noipex    disable automatic IP expansion with some commands.
-arc       read contents of well known zip, tar.gz and tar.bz2 archives
           as deep as possible, including nested archives.
           well known archives must have one of these extensions:
           .zip .jar .ear .war .aar .xpi .tar .tar.gz .tar.bz2 .tgz
           .gz .bz2 .odt .ods .odp .odg .odc .ott .ots .otp .otg
           to include further extensions, read below about SFK_ZIP_EXT.
           this binary (SFK Base/XD) can read only the first 1000 bytes
           of every archive entry. listing of contents is not limited.
           type "sfk help xe" for all details and restrictions.
-xarc      read contents of any zip file, regardless of file extension,
           and tar.gz and tar.bz2 files. reads the first bytes of every
           file and will therefore perform slower then -arc.
-wchar     activate EXPERIMENTAL utf-16 (ucs-2, wide char) decoding,
           allowing sfk find or filter to search text in utf-16 files.
           should not be used when (re)writing files. get more infos
           by typing "sfk help unicode".
-to mask   specify where to write output files with some commands.
           mask supports $file, $path, $base, $ext and more,
           like -to outdir\$base-modified.$ext
           say "sfk run" for a list of possible keywords.
-tofile x  specify a single output filename, which is taken as is
           and not checked for any $ patterns.
-tomake .ext  select only files that have no, or an older,
           counterpart file with extension .ext in the same folder.
-tomake outdir\$base.ext  select only files that have no or
           an older counterpart file in outdir with extension .ext.
           see "sfk run" for example: .wav to .mp3 conversion
-tmpdir x  set directory x as temporary file directory. default is
           to use the path specified by TEMP or TMP env variable.
-showtmp   tell verbosely which temporary files are created.
-keeptmp   do not delete the temporary files, if possible.
-nowarn    and -noerr, -nonote disable warn, error and note messages.
-memlimit=n set the caching memory limit to n mbytes (default=300).
           used if a function needs to load whole files into memory.
           if zip etc. archive processing is very slow, it may be caused by
           a cache overflow. try to increase the -memlimit then.
           if you think sfk uses too much memory while processing files,
           try to reduce -memlimit (values below 200 are not recommended).
           you may also set SFK_CONFIG (see end of this text).
-cachestat tell amount of memory used by archive file cache.
-nocache   disable the disk cache (for network files).
-exectime  tell command execution time at program end.
-noesckey  disable stop by escape key. (windows only)

shell return code handling and error processing:

-showrc    print sfk return code at program end. may not print anything
           in case of fatal errors, like wrong syntax (usually rc 9).
-exterr    in case of operating system related errors like file access,
           prints extended error information, if available.
-waitonerr wait for user input on every error.
-waitonend wait for user input at program end.
-stoponerr stop directory tree processing on first unreadable file.
           default is to process as many files as possible, skipping
           unreadable files and directories.
-rcfromerr some commands like filter, find, hexfind tell by shell rc
           that something was found. by default, skipped errors like
           unreadable files do NOT change this rc. with -rcfromerr,
           skipped errors do override the resulting shell rc.
-echoonerr echo whole command to stderr when an error occurs.
           see also the SFK_CONFIG setting "echoonstart" below.

to experiment with the above options, try "sfk errortest".

command local versus global scope:

   within a command chain, many options have an effect only locally
   with the command where they are specified, e.g. in

      sfk filt x.txt -case -high red FooCase +filt -high blue TheBar

   the "-case" is valid only for the first filter command.
   but the following options can also be used globally, if specified
   directly after "sfk":

      -nohead -noinfo -nofile -case -literal -spat

   for example, in

      sfk -case filt x.txt -high red FooCase +filt -high blue TheBar

   the "-case" is valid for ALL commands in the command chain.

environment configuration:

   set SFK_CONFIG=columns:n,active-file-age:n,memlimit:n,...
     columns:
       sfk (for windows) tries to autodetect the no. of console columns,
       but you may also set this value through this config parm.
     active-file-age:n
       some functions need to tell if a file is 'recently edited' or rather
       old and inactive. by default, files > 30 days of age are considered
       non-active. reconfigure the no. of days threshold here.
     memlimit:
       set memory limit to n mbytes.
     echoonstart:
       echo the whole sfk command on start, to stderr.
     echoonerr:
       echo the whole sfk command on errors, to stderr.
     tmpdir:path
       set folder for temporary files, used by some commands.
       e.g. set SFK_CONFIG=tmpdir:d:\tmp,memlimit:500

   set SFK_ZIP_EXT=".foo .bar .myext"
     set additional, user defined zip file extensions. in this example,
     files ending with .foo, .bar or .myext are also treated as zip files.
     for the list of default extensions, look above at the -arc option.
