All,
Below is the latest revision of the .start_synaptic script. Based on tests performed by roberts, a change was needed in order to make it work with DSL version 0.6.3.
Also, a RAMdisk size check was added to the program to prevent the LiveCD user from getting a mangled ramdisk. At least 96MB of RAM is required in order to run this script if you are running DSL from LiveCD or as a frugal/poor man's install. Keep in mind that if you only have 96MB of RAM available, you will not be able to use Synaptic to install any large programs.
To use the script, do the following. Copy the text below and paste it into a word processor like scite or nano. Then save the file as .start_synaptic in your /home/damnsmall directory.
Note the dot "." in front of the word start. Then make the file executable by opening an Xterminal (rxvt) window and type:
chmod 755 .start_synaptic
Finally, to run the script, type in:
./.start_synaptic
on a blank line inside the Xterminal (rxvt) window.
Here is the script text that you need to copy:
| Code Sample | #!/bin/sh
#
# .start_synaptic - Checks to see if the Synaptic package manager GUI is
# already installed and starts it up. Otherwise, it
# installs the program.
#
# Original author: cbagger01 from the Damn Small Linux forum
# Rev 2 4/09/04
# Revised to work with DSL version 0.6.1
# Do not use with DSL versions older than 0.6
# Added a ramdisk size check,
# and changes for DSL version 0.6.3
# Has this script called itself with the install argument?
