How-to rename multiple files in Linux
Sometimes you need to rename hundreds or thousands of files at once after one and the same scheme. Here are some examples how to rename the files in the linux terminal.
Rename all .htm files in one directory to .html
This will rename all *.htm files in the current directory and its subdirectories to *.html files. See the Linux manual pages "man bash", "man find", "man mv", "man sed" and "man pcrepattern".
All filename results from find are piped line by line to read and then processed by mv, editing the new filename with sed. This ensures that all paths with whitespace characters are processed correctly.
find . -type f -name '*.htm' | while read filename; do mv -v "${filename}" "`echo "${filename}" | sed -e 's/\.htm$/\.html/'`"; done
Rename all .ogg files in one directory to .oga
This will rename all *.ogg files in the current directory and its subdirectories to *.oga files. See the Linux manual pages "man bash", "man find", "man mv", "man sed" and "man pcrepattern".
All filename results from find are piped line by line to read and then processed by mv, editing the new filename with sed. This ensures that all paths with whitespace characters are processed correctly.
find . -type f -name '*.ogg' | while read filename; do mv -v "${filename}" "`echo "${filename}" | sed -e 's/\.ogg$/\.oga/'`"; done
Add additional file extension to all files
This will add an .old file extension to all files in the current directory, including all subdirectories. See the Linux manual pages "man bash", "man find", "man xargs" and "man mv".
find . -type f -name "*" | xargs -t -i mv {} {}.old
