# ~/.bash_aliases
#
# Simple command shortcuts.
# Keep aliases boring and predictable.
#
# Rule of thumb:
#   Use aliases for short, simple substitutions.
#   Use functions for anything with arguments or logic.


# ------------------------------------------------------------
# ls shortcuts
# ------------------------------------------------------------

# Long listing, show almost all files, classify file types.

# Show hidden files except . and ..
alias la='ls -A'

# Compact listing with file type indicators.
alias l='ls -CF'

# Human-readable file sizes.
alias lh='ls -lah'


# ------------------------------------------------------------
# Safer file operations
# ------------------------------------------------------------

# Ask before overwriting files.
#
# Some users like these safety aliases.
# Others avoid them because they do not want different behavior
# across different machines.
# alias cp='cp -i'
# alias mv='mv -i'
# alias rm='rm -i'

# Create parent directories automatically.
# Example:
#   mkdir foo/bar/baz
# alias mkdir='mkdir -p'

# Move up directories quickly.
alias ..='cd ..'
alias ...='cd ../..'
