Say you have a series of files you want to rename like so:
a37.zip to a37-archive.zip
b38.zip to b38-archive.zip
c39.zip to c39-archive.zip
and so on...
Here's a useful oneliner for bash:
for x in `ls`; do echo $x | sed -e 's/\(.*\).zip/\1-archive.zip/g'| xargs -t mv $x ; done
That should to it. Of course, there are other ways of doing it, but this way is fairly simple.
