Okay, I can display an environmental variable from the commandline:echo $COLUMNSAnd get a response.But I can't execute that from within a shell script, I get nothing.  So, there must be a way to import that environment variable - but I've not been able to find a simple solution/explanation.Once upon a time I recall seeing something like $ENV_COLUMNS, but that's not correct (or is missing something).I'm trying for something like this:    for x in $COLUMNS     do echo -n -    done    echo #to get the /n
How can I pass an environment variable to a script?
shell script;environment variables
