Basically the time portion which is always 00:00:00 needs to be stripped off and the space between the date and the next hyphen symbol (-) needs to be compressed.
Any ideas as to how to this ? Assuming they are about 3000 files in the directory.

Reason: Add ICODE tags.
However, run the "no action" option first and double-check if it spits the right result. Nonetheless, a making a backup of directory containing the files prior to the actual renaming process is *highly* recommended. You never know...
@junior-helper: thread opener stated he uses Korn shell, so chances are this is not a Linux system at all. There is a good chance that the "rename"-command is not there.

Basically this is a simple job: create a loop in which you run a command mv "$oldname" "$newname" in which you rename one file after the other:

This utility would be called once for every single file and this would add a lot of overhead to your script, which should be avoided.
Fortunately the shell itself offers a great way to modify strings too, without having to resort to an external utility: the "parameter expansion" or "variable epansion". The syntax looks awkward at first, but its execution speed beats every external utility by some order of magnitude. Twenty lines of this is perhaps still way faster than a single awk- (sed-, ...) call.
I suggest having a look into the man page for details, here is the solution for your problem as you stated it: remove a middle " 00-00-00" from a string:
Run with the print-statements to see how it works, remove them once you feel comfortable with the output.

Hi to everyone!!. Here's my stupid question of the day.
When I have to rename a file I use "mv filename newfilename".
But what about renaming multiple files, for example if I want to add the prefix "old" to several image files (in fact it's what I wanted to do..).
Thanks in advance.... :D (6 Replies)
