Useful CLI Tools

bat

A blend of cat, less, nl with syntax highlighting.

delta

A side-by-side diff.

exa

A “modern replacement for ls”.

These are my fish functions for the ls aliases I grew up with¹:

$ type ls ll la lh
ls is a function with definition
function ls --wraps=exa
  exa --classify $argv
end

ll is a function with definition
function ll --wraps=exa
  ls --long --links --git --header $argv
end

la is a function with definition
function la --wraps=exa
  ll --all $argv
end

lh is a function with definition
function lh --wraps=exa
  ll --sort=modified --reverse --color=always $argv | head -n 20
end

It also replaces tree:

$ type tree
tree is a function with definition
function tree --wraps=exa
  ll --tree $argv
end

1. my bash aliases for these commands

   $ type ls ll la lh
   ls is aliased to `ls -F'
   ll is aliased to `ls -l'
   la is aliased to `ll -a'
   lh is a function
   lh ()
   {
       ls -F -l -t ${1+"$@"} | cat - | head -n 20
   }
