@ -55,6 +55,8 @@ Notes:
|
|||
|
||||
- Learn about file glob expansion with `*` (and perhaps `?` and `{`...`}`) and quoting and the difference between double `"` and single `'` quotes. (See more on variable expansion below.)
|
||||
|
||||
- Use `alias` to create shortcuts or synonyms for commonly used commands. For example: `alias ll='ls -latr'` creates a new alias `ll`.
|
||||
|
||||
- Be familiar with Bash job management: `&`, **ctrl-z**, **ctrl-c**, `jobs`, `fg`, `bg`, `kill`, etc.
|
||||
|
||||
- Know `ssh`, and the basics of passwordless authentication, via `ssh-agent`, `ssh-add`, etc.
