根据正则表达式递归重命名目录和文件

Question

I am trying to strip all "?" in file names in a given directory who was got more subdirectories and they have subdirectories within it. I've tried using a simple perl regex script with system calls but it fails to recurse over each subdirectory, and going manually would be too much wasted time. How can I solve my problem?

Answer 1

You can use the find command to search the filenames with "?" and then use its exec argument to run a script which removes the "?" characters from the filename. Consider this script, which you could save to /usr/local/bin/rename.sh , for example (remember to give it +x permission):

#!/bin/sh
mv "$1" "$(echo $1| tr -d '?')"

Then this will do the job:

find -name "*\?*" -exec rename.sh {} \;

Answer 2

Try this :

find -name '*\?*' -exec prename 's/\?//g' {} +

See https://metacpan.org/module/RMBARKER/File-Rename-0.06/rename.PL (this is the default rename command on Ubuntu distros)

Answer 3

Find all the names with '?' and delete all of them. Probably -exec option could be used as well but would require additional script

for f in $(find $dir -name "*?*" -a -type f) ; do
    mv $f ${f/?/}
done
