Aliases are one of my favorite terminal customizations. They make the most frequently-used commands shorter and allow improvements on the standard ones, enabling you to tailor programming in the terminal to your individual needs and preferences. These aliases are stored in ~/.zshrc.

Listing files

The one alias that has improved my workflow the most is a quick, one-keypress command l. This replacement for the standard ls command prints the size, last-modified date and time, and the directory name of each file and sub-dir in the current directory. It orders the rows by the last-modified date, so the most current files and projects are up top on the list.

# Flags:
#   -G: default colors, different for directories vs. files
#   -F: includes a trailing `/` at the end of directory names
#   -l: display long format (file types, permissions, number of hard
#       links, owner, group, size, last-modified date, and filename)
#   -t: sort the list of files by modification time
alias l='ls -GF -lt | awk '\''{
  printf("%-4.4s ", $5);
  printf("%4s %-3.2d %-5.5s  ", $6, $7, $8);
  printf("%-7.59s\n", $9);   
}'\'' | tail +2'  # Remove first line from output (formerly "total")

When looking to filter through filenames quickly, I use lg #{regex}, which pipes the result of l to a case-insensitive grep command.

alias lg='l | grep -i'

Git

My git aliases are a close second to the directory listing commands. The ones I use most frequently are:

Alias Original Command
gac 'My commit message' git add -A && git commit
gp git push
gch #{branchname} git checkout #{branchname}
gb git branch
