I've been messing with the
chsh command so that I could change the name displayed in my shell before each command is issued, for example
picard@ubuntu:$. My problem arose when I gave the command
chsh -s /bin/ksh picard, not fully knowing what the results would be. Among this command, I also used
grep ksh /etc/shells/. Now, any time I try to open a terminal, be it bash, dash, sh or urxvt, it either just doesn't open or starts spawning instances of urxvt until it has so many open, the computer hangs and then the instances are all closed.
What exactly did I screw up? I really would prefer not having to reinstall, but I can't use Linux without a command line, which I'm sure you guys can sympathize with.
