## Everyday use
- In bash, use **Ctrl-R** to search through command history.
- In bash, use **ctrl-r** to search through command history.
- In bash, use **Ctrl-W** to delete the last word, and **Ctrl-U** to delete the whole line. Use **Alt-Left** and **Alt-Right** to move by word, and **Ctrl-K** to kill to the end of the line. See `man readline` for all the default keybindings in bash. There are a lot. For example **Alt-.** cycles through previous arguments, and **Alt-*** expands a glob.

- If you are halfway through typing a command but change your mind, hit **Alt-#** to add a `#` at the beginning and enter it as a comment (or use **Ctrl-A**, **#**, **enter**). You can then return to it later via command history.

- Use `xargs` (or `parallel`). It's very powerful. Note you can control how many items execute per line (`-L`) as well as parallelism (`-P`). If you're not sure if it'll do the right thing, use `xargs echo` first. Also, `-I{}` is handy. Examples:

- Stable sort (`sort -s`) can be useful. For example, to sort first by field 2, then secondarily by field 1, you can use `sort -k1,1 | sort -s -k2,2`
- If you ever need to write a tab literal in a command line in bash (e.g. for the -t argument to sort), press **Ctrl-V** **[Tab]** or write `$'\t'` (the latter is better as you can copy/paste it).

- For binary files, use `hd` for simple hex dumps and `bvi` for binary editing.
