case statement based on file availability
I need to make a select menu that gives options dynamically based on whether certain files are available. For instance:
PS3="Open which readme? " select readme in This That do case "$readme" in This) open -a /Applications/TextEdit.app This.txt;; That) open -a /Applications/TextEdit.app That.txt;; * ) echo "Invalid selection";; esac done } The catch is that if the file doesn't exist, it should not show in the menu, either. I'm fairly new to shell scripting, so any help would be appreciated. |
