The incredible amount of time this has saved over the years is great, but the real benefit never having remember either inspect archive files for the initial directory or remember to do this dance:

    % mkdir foo
    % cd foo
    % tar zxvf /path/to/bar.tar.gz  # or "unzip foo.zip" or "7x x foo.7z" etc
    % mv bar-1.2.3 ..
    % cd ..
    % rmdir foo

https://gist.github.com/Fannon/41b0a6104435943cd826

Without atool you have to either 1) create a temporary dir youself and do the dance I showed above, or 2) always inspect every archive before you decompress it to see if it has multiple top-level files, or 3) accept that typing "tar xvf" or similar will sometimes spam your current directory (often $HOME) with thousands of files.

Similar to how git tends to remove mental blocks around branching (you not longer have ot worry about the cost of making an arbitrary change), atool frees you from having to worry about how an archive was created. This has, in practice, saved huge amount of time and mental effort.

Use magit in emacs as a git front-end instead of dozens of git aliases. You can continue to use vi or eclipse or whatever for editing. Use dired in emacs to replace a lot of file manipulation aliases.

Replace all your complicated aliases with ^r reverse search. For example, instead of typing

    sudo dnf --refresh check-update

    ^rche

    HISTSIZE=100000                   # Lots of history.
    HISTFILESIZE=100000               # Lots of history in the file.
    HISTCONTROL=ignoreboth            # Ignore entries with leading white space and dupes.
    HISTIGNORE="ls:ll:cd:fg:j:jobs"   # Uninteresting commands to not record in history.
    shopt -s histappend               # Append history to file, don't overwrite.
    shopt -s histverify               # Show expanded history before running it.
    shopt -s cmdhist                  # Store multiline cmds as single

    }

ali <name of alias> <command>

to get it put this in your .bashrc

  function ali() {  
   echo "alias $1='${@:2}'" >> ~/.bashrc   #in ubuntu use   ~/.bash_aliases  
   echo "made alias:";  
   echo "alias $1='${@:2}'";  
   source ~/.bashrc;  #reload bashrc  
  }

And of course the alias to show the list of all aliases:

  alias alis='cat ~/.bash_aliases'

That only lists what's in .bash_aliases, along with any comments.

Why not just run alias without arguments? It lists all active aliases, however and whenever they were defined.

I find the oh-my-zsh git plugin's default aliases to be unintuitive and hard to remember. Simply not having to type 'git ' before everything is good enough for me.

Useful when you have a file picker in front of you, but you know you have a terminal already in the directory you want. Switch to the term, cpcd, switch to the file picker, Go to folder (⌘-Shift-G), Paste (⌘-V).

when you have a terminal open in a directory, but another app has a file picker box.

I've not actually used it as a script in a while, and it appears to be broken in that regard at the moment (something about ld not being able to write to the tmp directory). However, its Makefile is still operational. Maybe someone will see this and submit a PR that fixes it?
