Key value array in shell scripts! - Bash

Ahmed AbouZaid 23/07/2016 Bash, Tips and Tricks Comments

I really believe if you need key-value (aka associative array) in your script, then you need to move to a real language which most probably will be Python or so.

But for some reasons, you maybe need it in one of your bash scripts. And of course will not rewrite the script just for that part!

Emulate pbcopy and pbpaste in Linux with xsel - Bash

Efficient and quick search with find and grep - Bash

Ahmed AbouZaid 27/09/2015 Bash, Tips and Tricks Comments

When you need to search inside files, as linux user you will think in "grep", but when you try to search in zillion of files (or just thousands), grep isn't the best option for that!

It's very slow especially when you use "-r" option (recursive), even if you are going to use "fgrep" or "grep -F" (--fixed-strings) which interprets patterns as a list of fixed strings), thus it's a little bit faster because it treats the strings literally and doesn't try to parse them with regex.

For a long time I used "Gnome Connection Manager" to manage remote servers, however I moved to "Terminator". I really love Terminator, but If
