Trying to get a unique list of shells on my system. When I run this command:
cat /etc/passwd | cut -d ':' -f 7 | uniq
/bin/bash /bin/sync /sbin/shutdown /sbin/halt /bin/bash
I can't figure out why
uniq isn't doing what I want. What don't I understand?
I tried taking this output, making a copy, replacing one of the
/bin/bash lines with the other in the copy, and then
diffing the files and I got no output, so I'm guessing not a hidden character?
