Hey folks!
I have a bunch of files on a server that are in the format "filename_x.dat" and I need to rename them "filename.dat", i.e. strip to last two characters off the filename while maintaining the extension.
Here's yet another way of doing it, by using bash builtins: for _file in $(ls *_x.*); do _front=${_file%\_*} _back=${_file#*\.} mv $_file $_front.$_back done; The code may need to be tweaked slightly to deal with multiple underscores or multiple dots in the filename, and if they all end in .dat, then the logic is even simpler. --Skip
