In the bash below I am trying to loop through all the R1.gz in a directory (always 1), store them in ARRAY, and cut them before the second _. That is being done but I can't seem to print then one a single line seperated by a space. Is the below the best way or is there a better solution? Thank you .
It kind of depends what you want to do with the list. You can certain cut down the effort in your code by not starting lots of processes, but using Variable Substitution (look in the bash manual pages), perhaps like this:-
This is not unique though. Is that a problem? We can do sneaky things with what bash calls an Associative Array (or a Hash) like this:-
Okay, so that is not sorted. is that a problem?
I hope that these tricks help.
