Recursively remove filename suffix from files in shell

When we develop locally, we append ".dev" or ".prod" to files that should be made available only to the development/production server respectively.

What I would like to do is; after deploying the site to the server, recursively find all files with the ".dev" suffix (for example) and remove it (renaming the file). How would I go about 开发者_开发技巧doing this, preferably entirely in the shell (without scripts) so I can add it to our deployment script?

Our servers run Ubuntu 10.04.

Try this (not entirely shell-only, requires the find and mv utilities):

find . '(' -name '*.dev' -o -name '*.prod' ')' -type f -execdir sh -c 'mv -- "$0" "${0%.*}"' '{}' ';'

If you have the rename and xargs utilities, you can speed this up a lot:

find . '(' -name '*.dev' -o -name '*.prod' ')' -type f -print0 | xargs -0 rename 's/\.(dev|prod)$//'

Both versions should work with any file name, including file names containing newlines.

It's totally untested, but this should work in the POSIX-like shell of your choice:

remove-suffix () {
    local filename
    while read filename; do
        mv "$filename" "$(printf %s "$filename" | sed "s/\\.$1\$//")"
    done
}

find -name '*.dev' | remove-suffix .dev

Note: In the very unusual case that one or more of your filenames contains a newline character, this won't work.

for file in `ls *.dev`; do echo "Old Name $file"; new_name=`echo $file | sed -e 's/dev//'` ; echo "New Name $new_name"; mv $file $new_name; done

In an example of something I used recently this code looks for any file that ends with new.xml changes a date in the filename (filenames were of the form xmlEventLog_2010-03-23T11:16:16_PFM_1_1.xml), removes the _new from the name and renames the filename to the new name :

for file in `ls *new.xml`; do echo "Old Name $file"; new_name=`echo $file | sed -e 's/[0-9]\{4\}-[0-9]\{2\}-[0-9]\{2\}/2010-03-23/g' | sed 's/_new//g'` ; echo "New Name $new_name"; mv $file $new_name; done

Is this the type of thing you wanted?

find /fullpath -type f -name "*.dev"|sed 's|\(.*\)\(\.pdf\)|mv & \1.sometag|' | sh
