Just wanted to show an example of the Xdialog program that I mentioned
earlier:
During my administration tasks I need to visit a few dozen machines each
day. To facilitate this, I created a short script using both "dialog"
and "Xdialog" (the text and GUI versions). Here's a simple script using
Xdialog:
---START
#!/bin/ksh
MACHINE_LIST=~/.ssh/machine_list
while [[ "$RETCODE" -ne "1" ]]
do
Xdialog --menu "Choose server:" 24 35 16 `cat ${MACHINE_LIST}`
2>/tmp/choice.$$
RETCODE=$?
CHOICE=`cat /tmp/choice.$$`
rm /tmp/choice.$$
if [ "$RETCODE" -ne "1" ]; then
clear
xterm -e "ssh ${CHOICE}" &
fi
done
---END
To use it, do the following:
1) Install Xdialog
Grab the sources from http://xdialog.dyns.net/ and compile. I have
RPMs for Fedora, RedHat 9, and a few others.
2) Edit the ~/.ssh/machine_list directory and create a list of hosts and
descriptions. The file should look similar to this:
---START
epsilon Dell_Laptop
theta IBM_ThinkPad
gamma Cust_1
omega Depot_Sales
alpha Front_Office
omicron File_Server
---END
3) Optionally, configure SSH host keys on the remote server.
4) Run the script. (Watch the line breaks!)
You should get a menu showing the machine names. Double click on a name
to launch a new shell window.
As you can see, there's barely twenty lines of code but it can create an
application that would take perhaps 100 lines in another toolkit.
