Is it possible to remove multiple packages listed in a text file? Similar to “cat orphan.txt | zypper rm” or “zypper rm <orphan.txt.” Neither worked.
Thanks.
Hello ionmich,
There are probably lots of ways to do this, here’s one:
zypper rm `cat orphan.txt`
Good luck!
Have not tried this, but I would expect
zypper rm cat orphan.text
or
for i in `cat orphans.txt`;do
zypper rm $i
done
Wrong. This tries to remove the packages named “cat” and “orphan.txt”.
Hello Knurpht,
It works for me, note that it’s a ` not a ’ or ".

What do you think backquotes do in the shell?
That’s one reason the POSIX syntax for command substitution uses $( ) instead
zypper rm $(cat orphan.txt)
Another is that $()s can be nested(for the reeeeally hairy shell scripts) without very ugly quote mixing.
The back quotes have been deprecated for at least 10 years.
Thanks all. I like the script. Simple.
