Recitation 1d: Aliases (PowerShell users, skip this section)¶
Since we saw that rm
is a wrecking ball, we should temper it using the -i
flag. For safety, we would like rm
to always ask us about deletion. We can instruct bash
to do this for us by creating an alias.
alias rm="rm -i"
After executing this, any time we use rm
, bash
will instead execute rm -i
, thereby keeping us out of trouble.
One of my favorite aliases is to make ls
list things more prettily.
alias ls="ls -FG"
The -F
flag makes ls
put a slash at the end of directories. This helps us tell the difference between files and directories. The -G
flag enables coloring of the output, also useful for differentiating file types.
