Nice little feature presentation. I find that Linux Command is a useful site for moving on further.

I found the online FSL presentation on shell scripting to be particularly useful. It's cool that even folks involved in medical imaging have a reason to write scripts.

Did you try playing with Zenity? It is very good for making shell scripts return some nice GTK2 dialog boxes.
For instance, I have a button on my Xfce tool bar to execute the following script:

Code:

dhcpcd ath0 &&
zenity --info --text "You are now online with ath0." &&
ntpdate ntp.cyberdoc.dk &&
zenity --info --text "NTP has updated the system clock."

It looks like shown on this screenshot.

Anyone have a link to the system monitoring tool Chess referred to towards the end of podcast? It's not clear from the show how it's spelt.

Thanks

there is a really awesome thread in the ubuntu forums about conky. people post a screenshot with their .conkyrc file. good to look to see about new ideas and color schemes.

Near the end of the episode, Chess mentions creating a directory for all of your scripts and then adding that directory to your path in the '$HOME/.bashrc' file.

I am running Ubuntu Gutsy, and I cannot find any mention of a path in my .bashrc file.

Help?

I am running Ubuntu Gutsy, and I cannot find any mention of a path in my .bashrc file.

I find it in ~/.bash_profile.  Check there.  It looks like this and I think it came that way by default:

# set PATH so it includes user's private bin if it exists
if [ -d ~/bin ] ; then
    PATH=~/bin:"${PATH}"
fi

[FiremothPilot]

So this means that if I create the directory $HOME/bin and drop scripts in it, my profile is already set up such that I can execute said scripts without editing my bash_profile?

[ajlewis2]

Yes, if you have that in your ~/.bash_profile already. :-)
