Question cut, grep, regex, universal search and replaces
Is there a GUI program out there for the use of grep, cut, regex, and I need a powerful search and replace program ... Any ideas would be greatly appreciated!

ThankS!

You could use perl at the command line like this:
Quote:
perl -pi -e's/clown/bozo/' file1 file2 file3 fileN

or you could try:
Quote:
perl -pi.bak -e's/clown/bozo/' file1 file2 file3 fileN

to be safe. The original files would be named file1.bak file2.bak etc

Or, use SED in a shell script...
Quote:
cp ${file_name} ${file_name}.old
sed 's/search_string/replace_string/g' < ${file_name} > ${file_name}.tmp
mv ${filename}.tmp ${filename}

You can stick this in a loop to go thru all files in a directory.
