In a bash script,
I need that if a command fails, the script exits.
Now I do as follows:
++++++++
cat example.txt
if [ $? -ne 0 ]; then exit; fi;
++++++++
is there a more compact way of doing this?
something like
cat example.txt __SUCCESS_OR_DIE__

Hello Ahoffmann,
Thanks, it works.
But could you explain the solution a little bit, please?
what is "||"?
a double pipe? what does it mean?
what means "42" after exit?
I did "man exit", but instead of explanation about exit, there is a very short explanation about shell commands.
How to find the explanation of the arguments of exit?
Many thanks,
DAvid
