rename many files at once

to regex shell bash hints mv by hostmaster on Mar 05, 2008
This is where the bash variable handling makes it even more interesting. Instead of just doing something like "mv $var", we can replace text in the filename using this syntax:

${var/originaltext/replacetext}


So now, if we run this command on our directory:

for f in *;do mv $f ${f/test/prod};done

backup files
