How to remove special characters in file names?

Question

When creating playlists I often came across files that would break the playing process. Such would be files with spaces or apostrophes. I would fix it with the following command

for file in *.; do mv "$file" `echo $file | tr " " '_'` ; done **(for spaces)**

Now I more often come across files with commas, apostrophes, brackets and other characters. How would I modify the command to remove such characters?

Also tried rename 's/[^a-zA-Z0-9_-]//' *.mp4 but it doesnt seem to remove spaces or commas

Answer 1

for file in *; do mv "$file" $(echo "$file" | sed -e 's/[^A-Za-z0-9._-]/_/g'); done &
