 - 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:
-```bash
-      find . -name '*.py' | xargs grep some_function
-      cat hosts | xargs -I{} ssh root@{} hostname
-```

 - `pstree -p` is a helpful display of the process tree.
 
 - Use `pgrep` and `pkill` to find or signal processes by name (`-f` is helpful).
