Mass file rename?

[Ming]

I have a dir full of files with a .1 appended to the filename. How can I remove the .1 from all the filenames at once.

make a file with your favorite text editor called rmext with the following contents:
#!/bin/sh
#

ls * | while read file
do
newname=$(echo $(basename $file '.1'))
if [ "$file" != "$newname" ]; then
mv $file $newname
fi
done

Put this file in your "/usr/bin" directory. Then use this command on the file "chmod +x /usr/bin/rmext". I say to put it in your /usr/bin directory just because your path will point there and the chmod command makes the file executable.

Then whatever directory you're in just type rmext and **all** the files in that directory that have .1 on the end will have .1 removed.

So for example "xxx.1" will end up as "xxx" but "xxx.01" wouldn't change.
