Invoke replace in one of the following ways:
كود:
shell> replace from to [from to] ... -- file [file] ...
shell> replace from to [from to] ... < file
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
filenames 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:
كود:
shell> replace a b b a -- file1 file2 ...
