The replace utility program changes strings in place in files or
on the standard input.
Invoke replace in one of the following ways:
shell> replace from to [from to] ... -- file_name [file_name] ...
shell> replace from to [from to] ... < file_name
from represents a string to look for and to represents its
replacement. There can be one or more pairs of strings.
Use the -- option to indicate where the string-replacement list
ends and the file names begin. In this case, any file named on
the command line is modified in place, so you may want to make a
copy of the original before converting it. replace prints a
message indicating which of the input files it actually modifies.
If the -- option is not given, replace reads the standard input
and writes to the standard output.
replace uses a finite state machine to match longer strings
first. It can be used to swap strings. For example, the following
command swaps a and b in the given files, file1 and file2:
shell> replace a b b a -- file1 file2 ...
