So I have a case in my bash script or well a few that I need to check if a word is typed in any combination of upper and/or lower case letters (trust me I don't want to do "Back" | "BACK" | "back" | so on for every combination of upper and lower case characters of every thing that would add quite the length to my script.
Not only do I need this in case statements also need to be able to in an if statement where I compare the string "delete" and "Delete" and "DELETE" and so on to a variable.
why I'm so picky about this is when I name a file with anything thats the same word just different case it throws an error to the user and plus I also for ease of use want this. I would appreaciate some help on this as I'm struggling to find a simple answer.
I believe those are the only two situations I need this in thank you ahead of time you guys are great to me
oh and changing the variable before the rest of my script to all lowercase or uppercase isn't gonna cut it :P unless i ABSOLUTELY have to
found solution for if statements doing the whole [Aa][Bb] thing I was doing it wrong so it failed but now that works
if I do this to the case statement though things go very wrong when I type quit it exits...the terminal not just the script like it should :P any ideas? and funny thing is where I found this solution that worked for if statements the example on the site is a case statement :P yet it don't work :P before this test quit did exactly as it should btw
also another detail I would like to avoid shopt -u nocasematch if at all possible again it isn't gonna cut what I want but I may consider it since I believe I found a part of my script that if may have no choice but would like avoid it in the case section please if at all possible
so in a test I just did I found case isn't working because well I'm not sure yet but it wasn't the regex expressions
so now to find whats wrong. but if anyone care to explain how useful shopt can be I'm listening but I'll be in a moment when I fix this look it up myself but any opinions?
Just discovered the issue it's in the way I run the script. How can I make it if I run the script with . filename that when I do an exit 0 it doesn't quit the terminal too? ./filename doesn't do this nor does a symlink running it which probably be the main way of running the script but still I need it to not do this if it is to be run that way. Any ideas
all in all with no replies on this in time I have managed to fix this file up and have a couple bugs I wish to bring up I've found and see if anyone can help me but that is for another post this one is messy :P
