Stuck after typing goto

rairey · #1 (**permalink**) 09-20-2007

uname -a returns: SMP Tue May 17 17:52:23 EDT 2005 i686 athlon i386 GNU/Linux

I have many aliases beginning with "goto" so...
if I type goto and then hit return (oops)

A goto prompt pops up and I cant exit from it(I tried MANY key seqs)
The only way to exit is to kill the term window and launch another.

Anybody know how to exit from the goto prompt ??

Thanks
Ron

I dont type goto then hit return.

I type goto bla, then it gets stuck in the goto prompt.

bla could be anything, the point is, the typo is the space.
for example, if I have an alias "gotohome", I might type be accident
"goto home" and then I'm stuck.

just wanted to be clear...

Wow! I have never encountered this before! Yet another reason to avoid csh. You must be using csh or tcsh as your shell. If you would switch to bash, you would not have this problem. But when csh sees an input line like "goto fubar", it will actually skip all further input lines until it encounters a line labeled "fubar". You can supply such an input line the first time. After that, another "goto fubar" sends it back to where it encountered the line labeled "fubar". Nice design...not.

Code:

$ csh
%echo $shell
/bin/tcsh
%goto fubar
goto? hello
goto? echo $shell
goto? fubar:
%date ; sleep 2

%echo we are gonna loop
we are gonna loop
%goto fubar

Thu Sep 20 13:07:24 EDT 2007

we are gonna loop

I'm guessing that the "fubar:" line needs to be in the history list in order to loop, but I don't feel like testing that.
