Remove prefixes from filenames I have a bunch of files as follows: 04602635_b0294.DAT20120807164534 04602637_b0297.DAT20120807164713 04602638_b0296.DAT20120807164637 04602639_b0299.DAT20120807164819 04602640_b0298.DAT20120807164748 04602641_b0300.DAT20120807164849 04602650_b0301.DAT20120807164921 04602652_b0302.DAT20120807164956 I need to rename them to exclude the prefix. It needs to look like this.. b0294.DAT20120807164534 b0297.DAT20120807164713 b0296.DAT20120807164637 b0299.DAT20120807164819 b0298.DAT20120807164748 b0300.DAT20120807164849 b0301.DAT20120807164921 b0302.DAT20120807164956 **EDIT** I forgot to add that I am using Solaris.

for file in * ; do
echo mv -v "$file" "${file#*_}"
done


run this to satisfy that everything is ok.
if it is, remove `echo` from command and it will rename files as you want.


"${file#*_}"


is a usual substitution feature in the shell. It removes all chars before the first `_` symbol (including the symbol itself). For more details look here.
