[Bundle]Simple Newbies Module Script

Post#1 by **Bogomips** » 10 Sep 2014, 18:18

Dabbling with a script to take drudgery out of making modules from '.txz' files independently for testing, using method shown here. As a newbie one wishes to quickly make modules, juggling dependencies, for one's preferred programs from all sorts of sites, to try out. (Have to have kdelibs, and somehow or other managed to avoid KDE, the full monty.) Script is geared to system where space is sparse. Uses temporary installation(fakeroot) directory by default. (Don't expect production standard coding.)

Running without arguments (-q quiet):

Code: Select all

guest@porteus:~$ sh p10/Por/xzmod.sh 
Usage
=====
xzmod  [-q]  <File with '.txz' Package List>  [ <Fakeroot Directory>  [<Module File>] ]

1st Par: [<path>/]<file name>[.<ext>]   Text file holding list of '.txz' package files, one per line. If no extension try with '.txt', then without. Default module name set to basename minus extension.

2nd Par: [<path>[/<Assigned Dir>]]      Existing path for Temporary Fakeroot Dir, otherwise new Fakeroot Dir. Default module name reset to name of new Fakeroot Directory.

3rd Par: [<path>[/<Module Name>.xzm]]   Existing/Non-existing path for xzm Module File.

Also more options in comments, but KISS for now.

Sample Scenarios

Using as example, file with short packages list, required to create an Abiword dependencies module.

Code: Select all

guest@porteus:~$ cat abw_080914.txt 
p10/Por/Space/gtk+3-3.8.2-i486-2.txz
/tmp/usm/at-spi2-atk-2.8.1-i486-1.txz
at-spi2-core-2.8.0-i486-1.txz

Files listed one per line with relative or absolute paths.

Current directory as work directory and module directory: Module name taken from packages' text file name.

Code: Select all

root@porteus:/home/guest# sh p10/Por/xzmod.sh abw_080914.txt
Text File = abw_080914.txt
Basename without Extension = abw_080914
Default Module Name: abw_080914.xzm
