checking wether an inputed character is already in a variable
Hi,

i have a variable which holds a variety of letters. eg,
Code:
var=qwertyuiop

what i want to do is determine wether an inputed letter is already stored inside the variable, so i can say to enter a new one.

i have been playing around using tr and grep but nothing seems to work at all.

Please help, i am in dire need of assistance

It would appear that you, 602chrislys and strasner, at the least, are all working on the same sort of homework/coursework questions.

I am guessing you have been tasked with writing some sort of hangman program....

Please refer to the rules, especially rule 6:

If I am mistaken I do apologise.

Yeesh, I'm not sure which is worse...that I helped one of these people, or that AFTER I gave an answer, two more people created posts to ask the exact same question...
