Hi,
I wanted to write a script which display different prompt for session
made through SSH. SSH should set SSH_CLIENT and SSH_TTY variables, so it
should be easy to check. Unfortunately I am unable to write working if
for those two cases. In the end it seem that even simple test with “-n”
from manual (there with $MANPAGE) doesn’t work for me. Following function:
|function ntest
if test -n $NOT_SET_VARIABLE
echo "Non-zero"
echo $NOT_SET_VARIABLE
else
echo "Zero length"
end
end
|
returns:
|Non-zero
<empty line>
|
Of course variable is not set:
|$ echo $NOT_SET_VARIABLE
<empty line>
|
What is wrong in that code? How can I check if a variable is set?
