How would I go about saving an output in a vaiable. For example, if I enter:
ls -l
it will show the files. How would I go about saving the output in a variable? Is it possible at all?

2Welcome to Stack Overflow. Please read the [About] page soon. Your question title mentions C; your tags do not. There's an answer that's appropriate to the tags - but you can and should edit the title if that's correct. If you really want to do it in C, there's a deleted answer that's appropriate; you should retag the question, dropping terminal (and review the bash and shell tags). – Jonathan Leffler Feb 12 '14 at 21:27

I know three ways to do:
1) Functions are suitable for such tasks:
func (){
ls -l
}
Invoke it by saying func
2) Also another suitable solution could be eval:
var="ls -l"
eval $var
3) The third one is using variables directly:
var=$(ls -l)
OR
var=`ls -l`
you can get output of third solution in good way:
echo "$var"
and also in nasty way:
echo $var
