Hi, and welcome to LQ!
I'm not sure if I understand your request correctly, but:
Assuming you have a file "names" that has 10 filenames in it, like so:
Code:
file1.rar
file5.rar
file12.rar
...
you can just do the following to unpack only those:
Code:
for r in $(cat names); do unrar x $r; done
Cheers,
Tink
