How to remove a prefix from multiple files?

Question

I downloaded a lot of videos that are named like [site.com] filename.mp4 and I wanted to remove the prefix so that they are named like filename.mp4

Answer 1

Use parameter expansion with pattern replacement.

f='[site.com] filename.mp4'
mv "$f" "${f/\[site\.com\] /}"

Even Windows systems can execute a Bash.

This is a for loop:

for f in *.mp4; then
  mv "$f" "${f/\[site\.com\] /}"
done
