As a person raised by GUIs, an extra visual confirmation and an extra prompt is a nice touch. I also like when the system says “Oh, is that a directory? No problem, I’ll give you the usual treatment.” You know what I mean?

alias ls='ls --group-directories-first --color=auto -w 120'
alias ll='exa --group-directories-first -l'
alias la='ll -a'
alias lt='ll --tree'

alias cp='cp --recursive --interactive --verbose --reflink=always'
alias mv='mv --interactive --verbose'

# custom pwd
# - replace $HOME with ~
# - make everything before the last '/' green, and everything after white and bold
# - alias to p
alias pwd="pwd | sed 's:$HOME:~:' | sed -E 's:(.*/)([^/]+):\x1b[32m\1\x1b[0m\x1b[1m\2\x1b[0m:'"
alias p="pwd"

# custom cd.
# - prints the new directory after cd'ing.
cd () { 
    command cd "$@" && p;
}
alias c="cd"
alias '..'='c ..'
alias '...'='c ../..'

# For the '~' alias, we want to use the original cd because printing '~'
# again would be redundant.
alias '~'='command cd'

# custom rm.
# adds a '-r' flag only if there is a single argument and that argument
# is a directory.
# This is because I want the behavior of -I (interactive) to be the default,
# but I also want to have the -r flag available when I need it without being
# prompted for single files.
function rm () { 
  if [ $# -eq 1 ] && [ -d "$1" ]; then
    rm --verbose --interactive=once --recursive "$1";
  else
    rm --verbose --interactive=once "$@";
  fi;
}

# mkdir + cd (created as a function because they run on the current shell,
# which is what we want for cd)
mc () { 
  mkdir -p -- "$1" && cd -P -- "$1";
}

      See replies to this comment.

      That’s not necessarily the case. Most scripts will just run in the current environment (meaning your .bashrc will be used) and not define many/any arguments for commands like cp or rm.

      Your .bashrc file is read whenever you start a command line shell, so by the time you can even run a script you probably already invoked your aliases.

      Exceptions would be if you’re running a script from cron or running the script from another shell like sh or zsh.

        I just did a test and did a ./test.bash in my current environment which has an alias rm='rm -i' and the rm inside the script didn’t do the aliased/interactive version. At least on my system, you’re incorrect about the exceptions, as even a straight bash script called in terminal won’t use the aliases defined in the bashrc.
