Bash tips and tricks

Where the hell is the file that holds the hot keys for the terminal?

I can't get anything I want done through gconf-editor in this case, for that matter I have not found it real helpful for much of anything except getting icons off the desktop for things already in the menus.

It is just a lot easier to use nautilus and get the damned file and screw it up my self.

*I think...

In ect search for terminal,and its in the emulator script...could be wrong tho.

For xfce-terminal the configuration file is ~/.config/Terminal/terminalrc

I don't use gnome-terminal or metacity but I think gterm's rc might be kicking around the .config directory in home.

I know the damned thing is supposed to be in there somewhere but I can't find it.

There is no file like yours in xfce for gnome.

Well I've given up on the hotkey in terminal thing. I have no doubt it can be done but fucked if I can figure it out.

Best I can come up with is write a script to do it, give it a really short name, and dump it in /usr/bin . Not a true hotkey but it's as close as I can get.

Test Day
The most basic and important concept in any programing language is the test. Learning about the test program is essential to getting anywhere with bash.

A simple example of what you can do with test

Code: Select all

#!/bin/bash
if test $USER != root
    then
    printf "Must be run as root \n"
    exit 1
fi
printf "\n Got root! \n\n"

Let's take a closer look at the if
if test $USER != root

test is comparing the value of $USER to the string root. != means the if will be true if the comparison is false. Variables are called with a $ and $USER is a global variable that denotes the user running the script.

So if the user is not root then it will print "Must be root" and exit.
Otherwise the script will print "Got root!" and exit normally.
Oh and \n prints a newline

That is just a tiny taste of what test can do and how to use it. To really learn about test check out this guide.

I am trying to read that link in the evenings on the stable install. Haven't ever gotten the the bookmark on here in weird OS land until now, just too busy.

Thanks, you just gave me something to do on bad days (days when nothing breaks is a bad day). Have a lot of that in this test cycle. We just wait for the last problem to be fixed. Hell we can, most of us anyway, actually boot in and use the bugger.

The plymouth problem seems to be getting some folks real well though. Everything, including the HDD, stops dead. I am not having that much FUN. Doesn't bother me, I like being up and running.

I decided to start that Bash guide over and have been reading the intro. I do not know what version you are using but the latest from the GNU site is 4.1.

An easy way to get that is from the lucid repo (I just checked the version that I have).
