I'm renaming empty file extensions with this command:
rename *. *.bla
However, I have a folder with hundreds of such subfolders, and this command requires me to manually navigate to each subfolder and run it.
Is there a command that I can run from just one upper level folder that will include all the files in the subfolders?
Using find and xargs and basename would make the expression easier to read
Prepare a rename shell script like this (corrected to handle multiple files)
#!/bin/sh
if [ $# -lt 3 ]
then
echo "usage: rename.sh sufold sufnew file1 (file2 file3 ...) "
exit
fi
sufold=$1
sufnew=$2
shift
shift
for f in $*
do
echo "to mv " $f `dirname $f`"/"`basename $f $sufold`$sufnew
mv $f `dirname $f`"/"`basename $f $sufold`$sufnew
done
Then you could invoke that to each file matched your criteria, including recursive folder search by find command
find . -name "*." | xargs rename.sh "." ".bla"
A more common sample
find . -name "*.htm" | xargs rename.sh ".htm" ".html"
