Shell Programming and Scripting

I have a set of folders like Jan1st, Jan2nd, Jan3rd... and so on.
I need to rename them to Jan1st2010,Jan2nd2010 .... and so on at one shot.

Try this:

Code:

find /path/to/your/dirs/ -type d -name "Jan*" | xargs rename -n 's/$/2010/'

It will not do anything, just tell you what it would do. Then, if you like what you see, just take out the -n switch, and it will do the renaming. Like this:

Code:

find /path/to/your/dirs/ -type d -name "Jan*" | xargs rename 's/$/2010/'

Note that you will have to do the 'rename' utility, that uses perl regex's. If you type 'rename' and see something like this:

Code:

$ rename
Usage: rename [-v] [-n] [-f] perlexpr [filenames]

You are good to go. Otherwise try to invoke 'prename' instead of rename.

But rename will not work with folders I guess

Code:

$ ls -1d Jan* | awk ' { print "mv "$0" "$0"2010" } ' | sh

It does on my linux box. What system are you on?
