I lent a friend a computer with Ubuntu 12.04 LTS on it, and he messed up the cat command.
$ cat testfile.txt
cat: meow!
$
Can someone tell me how to fix this? please?
Output of which cat:
/bin/cat
If he's a friend, he probably did something of the style (as root)(1):
mv /bin/cat /bin/cat.orig
echo "echo 'cat: meow! '" > /bin/cat
chmod 755 /bin/cat
If he's less of a friend, he omitted the first line.
Asking apt-file
apt-file search -F /bin/cat
says that the package is coreutils. You can probably reinstall it, although I see it as a bit of a dangerous thing...
(1) well, I really would have added alias which="echo cat: is a siamese" to your .bashrc, but well...
