How do I reuse the last output from the command line? Just a note, remember that this is rerunning the command. If your command has side effects, this may not work for you. |

stty: : Invalid argument I'd do: (1) log in. strace -p <pid of current shell> -o /some/file -f (2) run your script (3) kill the strace (4) use your grep/sed skills to see all the file open()s in the strace log (5) grep through those for stty. I do this regularly when i don't know what's happening. |

Determining what process is bound to a portnetstat -p above is my vote. also look at lsof. |

Where can I find the source code for `uptime`? A debugging tool I like is strace. It will show all the syscalls your application makes. If you run strace uptime it would show (after loading) open calls on /proc/uptime and /proc/loadavg. Though it doesn't show everything, it's sometimes a decent start on reverse engineering |

/etc/rc.d vs /etc/init.d Sorry, but /etc/init.d is the standard, as part of the SVR4 standard that Linux start scripts copied. |

What are your favorite command line features or tricks? yeah, very useful. You should quote openbox though ( '[o]penbox'). The brackets will work as kind of a glob, so if there is openbox in your directory (say you're in /usr/bin) bash will just use openbox, which will prevent the grep trick. |
