Hello,
I have something that looks like this:
if (grep("$KEY",EXISTING)){
In the event that this is true, I want to print the data that makes it true.
In other words, I want to print the line from EXISTING that contains the
pattern from the variable $KEY. The problem I am having is figuring out
where that line is. Is it stored in a variable I don't know about? If not,
how can I obtain this data? I realize this is a pretty basic question, but
I am having a tough time finding the answer and I need to get this done.
Any suggestions/help would be greatly appreciated.
Thanks,
Chuck Orr
