replace

REPLACE(1)						      General Commands Manual							REPLACE(1)

NAME

       replace	-  A utility program that is used by msql2mysql, but that has more general applicability as well. replace changes strings in place
       in files or on the standard input. Uses a finite state machine to match longer strings first. Can be used to swap strings.

USAGE

       replace [-?svIV] from to from to ... -- [files]

       or

       replace [-?svIV] from to from to ... < fromfile > tofile

SYNOPSIS

       replace [-?|-I] [-s] [-v]

DESCRIPTION

       replace

       -?|-I  info

       -s     silent

       -v     verbose

EXTRA INFO

       Special characters in from string:

       ^     Match start of line.

       $     Match end of line.

            Match space-character, start of line or end of line. For a end  the next replace starts locking at the end space-character.  A	
	      alone in a string matches only a space-character.

EXAMPLE

       this command swaps a and b in the given files:

       shell> replace a b b a -- file1 file2 ...
