Hi,

I have these files:
$ ls -a
. .. a.zip b.zip .c.zip .d.zip e.zip

Two hidden and three not hidden files.
I want to rename all of them whith an extension '.a' for example.


if I do:
$ for f in *.zip; do cp $f $f.a; done
$ ls -a
. .. a.zip a.zip.a b.zip b.zip.a .c.zip .d.zip e.zip e.zip.a

Only the not hidden files were renamed.


With:
$ for f in .*.zip; do cp $f $f.a; done
$ ls -a
. .. a.zip b.zip .c.zip .c.zip.a .d.zip .d.zip.a e.zip

Only the hidden files were renamed.


I tried to issue:
$ for f in .?*.zip; do cp $f $f.a; done and some derivations of the ? as in regular expressions, but couldn't achieve what I want.
How can I do it?

Hi,

This works:

for f in .*zip *zip; do .....

Hope this helps.

don't rename "." and ".." !! These are the shorthand for "here" and "one up". I don't know what happens if they are re-named...or even if you can.

The solution suggested by druuna is the answer to the question. FYI, dotglob is a shell option that controls the behavior of globbing, allowing the expansion of hidden files. You can toggle it using the shopt built-in:
Furthermore, as you can see, it does not expand . and ..

The more I know, the more I like it!

Thanks for the answers!
