I have an extremely annoying problem with regular expressions! At this point i believe the command 'read' is causing the problem due to the carriage return it places once its done.
I have an continuous loop until the input is correct: (After initial read statement)
Whats highlighted in bold is the problem. Every time it reaches it, nothing is allowed ! Not even if the input is completely valid as in:
abcd
What i want it to do is accept ONLY a-z characters and nothing else - no spaces either. In theory it should work however in practice i really do believe the 'read' command is giving me the trouble. Maybe a chop-esque function is required such as the one in perl.
I hope you guys can help! Thank You. -shell is BASH
Yeah, it seems so pointless ... Either the syntax is wrong or the guys behind the development of BASH got this one slightly wrong ...
I mean what i can do is individually check each character but its excessive code - 5 lines compared with 1. So if the experts can give me some advice, it would be much appreciated.
That does not seem to work on my end, possibly because your shell is bash3 but im not too sure of the difference between it and bash. I tried using the reverse syntax but no luck there, i get a few errors in doing so.
It does look like I'm going to have to use some longer code - just seems so silly that this little bug (if thats what it actually is) is causing me grief lol. Thanks for your help though.
Occasionally I make a mistake in my shell that results in there being a > for the prompt instead of the normal $.
Today I accidentally left off a " in a sed command,
sed s/\"//g" infile > outfile

Hi
Is there any way to turn off the (often ridiculously big) tooltips that are displayed when hovering over a topic in a topic list? It's driving me nuts.
Thx.
