Need help with very small script.

I'm setting up icewm to use on a laptop and would like to use some of the KDE 16x16 icons, but they need to be changed from .png to .xpm and renamed so that they end in "_16x16".

I can do this one file at a time using ImageMagick from the command line as follows:

>convert filename.png filename_16x16.xpm

but, when I try adapting some of the script examples (not specifically for this) I found searching this sight and googling, I cant get it to work. I'm just a little too noobish with scripting and variables.

Any help would be appreciated.

Sorry for being so dopey

Thanx

I think

rename .png _16x16.xpm *

will do it when issued inside the directory where the files are. Take a look at
man rename

try it out on a backup directory first though.

erm i'm not sure if renaming will address the issue of the file format needing to change...
If you do perl yould use the ImageMagick module for perl and in general the psuedo code for that would be
opendir (DIR, /usr/share/kde/icons);
while <DIR> {
Imagemagick::convert shift
save
}
closedir

or something close to that...haven't used image maick in a long while

right. That was silly of me. I was just looking at the renaming part.

Hey guys,

Thanks for the responces -

Ya, the first suggestion doesn't quite do it.

Technomage1 - I haven't tried your suggestion yet. But, I have another question for you. If I were to use The Gimp, is ther a way to perform batch file converions from within the program like in paintshop pro and other programs, and then use quatsch's suggestion for batch renaming?

Honestly, Gimp does a better job at conversion.

What about somethign like this - sorry I haven't had time to test it properly:

#!/bin/bash

# Pass the dir to look in as the first argument

for file in `find $1 -name *.png`; do
name=`echo $file | sed 's/\.png/_16x16\.xpm/'`
convert $file $name
done

Thanks for the scripting suggestions. I'm going to try them tonight.

I have one other question for any of you. After looking further into it, it appears that there is no way for Gimp to do this. You can do some perl scripting provided you have gimpperl installed, however I upgraded to 1.3.x and since its GTK2 base and the perl libs are GTK 1.2 based - well perl is out of the question and I'm back to ImageMagick and convert.

So my question is this. When I did the following - >convert *.png *.xpm I hosed all the file names (I tested on a test file ) getting xxx.xpm.1 through xxx.xpm.125 with xxx not having any relation to the original file name. David, will your script preserve the names at all?

Thanks alot for your input.

The script I suggested should convert images one at a time the convert command would be:
convert /path/to/picture_of_me.png /path/to/picture_of_me_16x16.xpm

So it will keep the first part of the filename the same.

Thank you very much.

I'll try it tonight when I get home from work and let you know how it goes.

Steve
