What's a handy terminal command you use often? - eviltoast

    I went a little overboard and wrote a one-liner to accurately answer this question

    history|cut -d " " -f 5|sort|uniq -c|sort -nr|head -5

    Note: history displays like this for me 20622 2023-02-18 16:41:23 ls I don’t know if that’s because I set HISTTIMEFORMAT='%F %T ' in .bashrc, or if it’s like that for everyone. If it’s different for you change -f 5 to target the command. Use -f 5-7 to include flags and arguments.

    My top 5 (since last install)

       2002 ls
   1296 cd
    455 hx
    427 g
    316 find

    g is an alias for gitui. When I include flags and arguments most of the top commands are aliases, often shortcuts to a project directory.

    Not to ramble, but after doing this I figured I should alias the longest, most-used commands (even aliasing ls to l could have saved 2002 keystrokes :P) So I wrote another one-liner to check for available single characters to alias with:

    for c in a b c d e f g h i j k l m n o p q r s t u v w x y z; do [[ ! $(command -v $c) ]] && echo $c; done

    In .bash_aliases I’ve added alias b='hx ${HOME}/.bash_aliases' to quickly edit aliases and alias r='source ${HOME}/.bashrc' to reload them.
