Bash脚本-隐藏目录中的所有文件

Question

I'm using the following script to make all files in a directory hidden by adding a dot "." at the beginning.

GLOBIGNORE=".:.."
for file in *; do
     mv -n "$file" ".$file";
done

How can I exclude the already hidden files?

Thanks for your help!

Answer 1

The wildcard already doesn't match any hidden files, unless you have separately enabled dotglob .

If you have configured dotglob to include hidden files, you can momentarily turn it off with

shopt -u dotglob

Using GLOBIGNORE enables dotglob so maybe the simplest fix is to take that out. You could also change it to

GLOBIGNORE='.*'

but this is effectively the same as unsetting it.
