About
Hello, my name is Zeth, I'll be your host here.
Command Line Warriors is about taking control of your own technology, it looks at our experiences of computing; especially using GNU/Linux, the Python programming language, the command-line and issues such as techno-ethics, best practices and whatever is cool now. If you take control of your technology then you are a Warrior too!
This site is your site too which means that you can contribute and get involved. You can leave comments using the facility provided. For me, the comments and discussions are by far the best part of the site. So please do have your say!

Is the watch command you're describing a Linuxism? On my FreeBSD box, "man watch" seems to be describing something completely different.

Thanks dude, I have a machine on my local network that I ssh into all the time and it never even occured to me that there was a passwordless login option - thats gonna save a lot of irritation for me :)

Gah, don't use passwordless SSH keys! Use ssh-agent instead - it achieves the same thing, but with one less possible-security problem.. http://upc.lbl.gov/docs/user/sshagent.html
If you don't like the emacs'ish keybindings, in bash you can run "set -o vi" and Esc toggles between regular insert mode, and vi-command mode (where 'dw' delets words, 'j' scrolls up the command-history etc). That said, the emacs'y bindings are probably more practical (modal editing in a command line isn't terribly useful)..

I'll just add:
Meta-b One word back Meta-f One word forward Meta-d kill word forward
...to the list of nifty keyboard shortcuts in the shell.

Awesome-- never knew about the cut/paste commands within bash. That'll be a lifesaver some day. Some additional bits of awesome:
For those times you don't want to type out an argument that you just typed again, you can use !:# as a stand-in or a previous line's arguments. Once you hit enter, the command is then printed out so you can see what you did, or in zsh you can hit tab and it will autocomplete.
omg:~ keke$ mv filename1 filename2 omg:~ keke$ mv !:2 !:1 mv filename2 filename1 omg:~ keke$
And... For those times that you need to re-enter a whole line, say you forgot to sudo a command, there's !!
omg:~ keke$ port install naim Error: permission denied omg:~ keke$ sudo !! sudo port install naim Password: ---> Fetching naim
It's freaky how many weird shortcuts there are in bash, and googling finds many. For instance, there's a find-replace shortcut for the last command:
omg:~ keke$ echo "this is so horrible" this is so horrible omg:~ keke$ ^horrible^amazing echo "this is so amazing" this is so amazing
Go Bash!

Ah, addendum-- you can expand the shortcuts in bash to make sure you know what you're typing by entering a space and hitting tab.

Ooh, and meta, ctrl+e writes out the command too; instead of space, tab. They probably behave differently.
Reading the man page for bash now, and it's just crazy.

I agree with DBR, never ever use passwordless public keys. Yes they're convinient, but there's a much easier way (sshagent as DBR mentions). In fact, in Ubuntu and Mac OS, there are graphical SSH Agents that automatically pop up when you have a key with a passphrase, asking if you want the OS to remember it (basically, doing what sshagent does, but graphically). For the sake of typing a passphrase ONCE, you have secure keys that - if stolen - still cannot be used.
Useful tips though! :) (I have subscribed to your RSS)
