joining values into one variable

[eyetry]

Not a unix person but need to update unix/linux script.

Essenially, I added a new optional input parameter to a script. If the parameter has content I need to append it to another value for later use in the script.

if [ _ENCRYPTION_SIGNATURE = "" ]
then
set P_SIG = ""
else
set P_SIG = "--sign -u " _ENCRYPTION_SIGNATURE
fi
echo p_encrypt_sig value = _ENCRYPTION_SIGNATURE
echo signature = $P_SIG

The echoed value of p_sig ends up null. What is wrong?

p_encrypt_sig value = ddmn-3m-qa
signature =

What shell are you using? Unless it is C shell, try removing the "set"s and the spaces around the "=". Also, if P_ENCRYPTION_SIGNATURE is a variable (I presume it must be otherwise the if statement would always be false), then it needs to be prefixed by $ to obtain the value of the variable.

Something like this:

   if [ "$P_ENCRYPTION_SIGNATURE" = "" ]
    then
      P_SIG=""
    else
      P_SIG="--sign -u $P_ENCRYPTION_SIGNATURE"
    fi
    echo p_encrypt_sig value = $P_ENCRYPTION_SIGNATURE
    echo signature = $P_SIG

HA! Thanks, thought it was something easy. Tried removing 'set'. Didn't realize it was space sensitive.
