BASH：查找并重命名文件和目录

Question

I would like to replace :2f with a - in all file/dir names and for some reason the one-liner below is not working, is there any simpler way to achieve this?

Directory name example:

AN :2f EXAMPLE

Command:

for i in $(find /tmp/ \( -iname ".*" -prune -o -iname "*:*" -print \)); do { mv $i $(echo $i | sed 's/\:2f/\-/pg'); }; done

Answer 1

You don't have to parse the output of find :

find . -depth -name '*:2f*' -execdir bash -c 'echo mv "$0" "${0//:2f/-}"' {} \;

We're using -execdir so that the command is executed from within the directory containing the found file. We're also using -depth so that the content of a directory is considered before the directory itself. All this to avoid problems if the :2f string appears in a directory name.

As is, this command is harmless and won't perform any renaming; it'll only show on the terminal what's going to be performed. Remove echo if you're happy with what you see.

This assumes you want to perform the renaming for all files and folders (recursively) in current directory.

-execdir might not be available for your version of find , though.

If your find doesn't support -execdir , you can get along without as so:

find . -depth -name '*:2f*' -exec bash -c 'dn=${0%/*} bn=${0##*/}; echo mv "$dn/$bn" "$dn/${bn//:2f/-}"' {} \;

Here, the trick is to separate the directory part from the filename part—that's what we store in dn (dirname) and bn (basename)—and then only change the :2f in the filename.

Answer 2

Since you have filenames containing space, for will split these up into separate arguments when iterating. Pipe to a while loop instead:

find /tmp/ \( -iname ".*" -prune -o -iname "*:*" -print \) | while read -r i; do
    mv "$i" "$(echo "$i" | sed 's/\:2f/\-/pg')"

Also quote all the variables and command substitutions.

This will work as long as you don't have any filenames containing newline.
