UNIX for Dummies Questions & Answers

Hi!

So i've got this shell script that asks questions and the user is required to input answers. The answers typed are bold.

Code:

sh-*.*$ sh filename dir
cat question
tput bold
read ans
tput sgr0
... and so on
tput sgr0
exit

So when the script ends i don't get the bold characters anymore. But when i end the script 'abruptly' (like i press Ctrl+C during the script usage), or when i type sh filename wrongdir and get the corresponding error messages, i get this:
sh-*.*$

I don't want to type reset whenever it happens; not that i don't like it but i shouldn't be doing it.

In a nutshell, i want everything normal characters as soon as the script closes, whether it was manual exit, error messages, of end of script.

Thanks in advance.

Try putting 'trap reset EXIT' at the top of your script. When it gets a trappable signal that forces it to quit, it should run 'reset' and make your terminal sane again before it does so.

hey thx alot !!! it actually also solved what would have been my next question.

I also wanted to know how to make my script exit anytime i entered 'exit' without doing nested ifs mumbo jumbo coz i tried that at one point :S

your suggestion fortunately took care of that too

kudos

I actually tweaked the command and instead put

Code:

trap "tput sgr0" exit EXIT

as the reset command was too radical

Solved this one nevermind
