Hey guys another question that I got - I am new in bash and I need to merge few files , remove repetitions and sort them alphabetically. I am not allowed to use temporary files. CleanLines script doing echo . I can redirect it to the script that merge and again redirect merge to remove Repetitions and that at the end redirect again to sort script. Is it the easiest way to do that ?

You need to add a space after the if.

if[[ line == temp ]]; then   # wrong
if [[ line == temp ]]; then  # still wrong, but see below

But that still compares the literal strings line and temp. If you want to refer to the values of the variables, you need $ signs:

if [[ "$line" == "$temp" ]]; then # right

The double quotes on "$temp" prevent it from being interpreted as a glob pattern; I also added double quotes on "$line" just for symmetry.
