UNIX for Dummies Questions & Answers

hi all
i have a directory which contain file
20060101-66666-09-08-0.tif
20060101-77777-11-12-0.tif
20051231-54221-66-55.tif
20051231-54221-66-44.tif
as you can see the name of the two last files is shorter then the first ones
i want to take all the files with the shorter name and to add to their name
-0 before the .tif (format as the two forst files)
how shall i do it?
thanks in advance
note:this are just example to the name of the files
i have something like 600 files.

Something like this maybe?

Code:

sed -n 's/\(.*-[0-9][0-9]\)\(\.tif\)/echo mv "\1\2" "\1-0\2"/p' file | sh

If it looks like it does what you want it to do, take out the "echo" and run it again.

hi
thanks for quick response
i did like you've wrote
here are the result
sed: -e expression #1, char 57: Unmatched ) or \)
it's an error
can you please tell me what is wrong
and please a little explanation about the command.
thanks

I made a mistake but I edited the posting quickly; sorry if you got the wrong version.

There are multiple dialects of sed out there, so it's also possible that your sed simply isn't compatible with mine.

This prints file names which have two digits before the .tif extension and adds a -0 before the extension.

hi era
i'm sorry it was my mistake i did it from a directory which i don't have a grant
to.
however now i did it from other directory
and this is what it worte
sed: can't read file: No such file or directory
can someone tell what is the problem ?
thanks you

It expects the list of file names in a file called file. Sorry for not making that clear.

Try this instead:

Code:

ls | sed -n 's/\(.*-[0-9][0-9]\)\(\.tif\)/echo mv "\1\2" "\1-0\2"/p' | sh

thank you very much .
it works great
