Run many commands in a loop, inserting a counter variable with sfk runloop for Windows, Mac OS X, Linux and Raspberry Pi (free open source).
  • 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 runloop ifrom ito "your command $[digits]i" [-yes] [-nohead] 
sfk runloop ifrom -steps=n [-inc=i] "your command $[digits]i"
sfk printloop ifrom ito "your text $[digits]i"

run a self-defined command many times, or simply print text to
the console, with a counter starting at ifrom, running until ito,
or running n times if -steps=n is specified.

with runloop, execution of commands is just simulated by default,
so nothing happens. as soon as your command is looking well, add
option "-yes" to really execute.

options
   -inc=i    increment step counter by i instead of 1.
   -spat     support slashpatterns like \t \q \xnn.
   -delay=n  wait n msec after every executed command.
   -nohead   does not display the [simulating:] info text.
             printloop is the same as runloop -nohead.
   -quiet    does not echo the commands before execution.
   -quietrc  do not print rc status message per command.

command string format
   the command string may contain $i which is replaced by the
   loop counter, or slashpatterns if option -spat is given.
   due to syntax limitations of the command shell, it may help
   - to use \q instead of \"   (avoids quote miscounting at shell)
   - to use \x26 instead of &  (if ampersand is behaving unexpected)
   $i also supports format parameters before 'i' like:
      $5i    print 5 digits, right justified, filled with blanks.
      $05i   print 5 digits, right justified, filled with zeros.
      $-5i   print 5 digits, left  justified, filled with blanks.
   to print the $ char itself in output use $$

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

aliases
   sfk printloop  do not execute anything but just print
                  the resulting text to terminal.

see also
   sfk run - run self-defined command on filenames.

examples
   sfk runloop 1 100 "copy mytest.dat testfile_$03i.dat" -yes
      creates 100 copies of mytest.dat named testfile_001.dat,
      testfile_002.dat, testfile_003.dat etc.

   sfk printloop 1 100 -spat "<a href=\qhttp://...&page=$i\q>$i</a>"
      creates html code containing 100 web links. note that \q was used
      instead of \", as '&' may create problems when combined with \"
      (a syntax mess produced by the command shell, not by sfk itself.)
      and to enable slash patterns like \q, -spat had to be added.
 
sfk runloop ifrom ito "your command 
   $[digits]i" [-yes] [-nohead] 
sfk runloop ifrom -steps=n [-inc=i] "your 
                    command $[digits]i"
sfk printloop ifrom ito "your text 
   $[digits]i"

run a self-defined command many times, or 
simply print text to the console, with a
counter starting at ifrom, running until
ito, or running n times if -steps=n is
specified.
