unhide hidden files in unix with sed and mv commands

Question

i wonder if u could help me with fixing bash script which should unhide all hiden files in dir. Where is the problem?

param='.'
for file in $param*; do
mv $file $(echo $file | sed 's/^.\(.*\)/\1/')
done
exit

Answer 1

This for loop should work:

export GLOBIGNORE=".:.."
for file in .*; do
   mv -n "$file" "${file#.}"
   # mv -n "$file" "${file:1}"
done

PS: Better to backup your files before doing a mass mv/rename
