Greetings
Im am not a perl programmer yet I am trying to learn and am debugging someone elses perl run script for use on a centos production box I have and I came across this
elif [ -z "${SMTP_CDB:-}" ]
Can someone please shed some light on what this eval means in English please?
im mainly concerned with the stuff between the two " yet I need all the help I can get
what does that say? Im trying to figure out if there is a typo or something in the script.
I am not a perl programmer yet im sure I will be before I get done with this exercise in the next coupla weeks
Thanks and kind regards
