Re: OT: running a command on many files in many subdirectories
Well, I wish I had gone and goofed off for the rest of the evening then come in and used one of these 2-3 line solutions this morning. Still, I learned some things reading them and will use them and the tldp reference for future scripting. Thank you, Levi -- To UNSUBSCRIBE, email to [EMAIL PROTECTED] with a subject of unsubscribe.

OT: running a command on many files in many subdirectories
I'm sure this is simple, but maybe someone here can help me do it in a few minutes instead of hours. I have a bunch of files in a bunch of directories, and I want to run the same command on each of them. For each input file, the output file should have the same name except ending in .txt, and the output files should be put a common directory. ie, java ImageInfo dir1/pic1.jpg commondir/pic1.txt etc, repeated over a bunch or directories and jpg files. The subdirectories only go one deep. If this is difficult I could copy all the jpg files into a single directory first with only a little bit of tedium.

OT: running a command on many files in many subdirectories
Never mind, I finished the task. I just first copied all the files into one
directory using:
find . -name *.jpg -print | xargs -i cp \{\} all/
Then wrote (modified, actually) a shell script to run imageinfo on a bunch of
files with a different output file each time:
#!/bin/bash
# run imageinfo on many files
ARGS=2
E_BADARGS=65
if [ $# -ne $ARGS ]
then
echo Usage: `basename $0` (extension of input files) (extension of output
files)
exit $E_BADARGS
fi
{
for filename in *.$1
do
java ImageInfo $filename ${filename%.$1}.$2
done
}
exit 0

You could use either wildcards or 'find' for the your-list-of-files part. Cheers, -- Colin Watson [[EMAIL PROTECTED]] -- To UNSUBSCRIBE, email to [EMAIL PROTECTED] with a subject of unsubscribe.
