RE: change all files in directory
Message ID:
Somewhat related question:

I want to ADD a file extension (there currently none)to all files that start
with "FOO"
so they will be named FOO.txt

Is there a one liner that can accomplish this?

Yeah, here is an easy solution, run it right at the command line...

(Make a backup of the files first!!)

perl -pi -e 's|satellite|target|' *.cpp *.hpp *.asc
perl -pi -e 's|Satellite|Target|' *.cpp *.hpp *.asc
perl -pi -e 's|SATELLITE|TARGET|' *.cpp *.hpp *.asc

Hello, I am trying to change all files in a directory that contain the
strings Satellite satellite and SATELLITE that I need to change to target,
Target and TARGET. Because many of these are C++ source files I need to
preserve the case. I was thinking of the following script:
#!/usr/bin/perl -w
@FilesInDirectory = <*.cpp *.hpp *.asc>;
foreach $FileName (@FilesInDirectory) {
            open(IN, $FileName);
            while<IN> {
$_ =~ s/satellite/target/;
$_ =~ s/Satellite/Target/;
but this just doesn't seem as efficient as it can be. I was trying to think
of regex that could do it all in one line but it seemed so much simpler to
do it in three.
Any thoughts,
