Parsing all subdirectories and running commands

[czarj]

Hey everyone,

I need some help. I am trying to write a small UNIX script that will go through all the subdirectories within a main directory and perform a command line function in each (call the function “resize-image”). In addition it is important that if the script encounters an error it skips that subdirectory and moves on to the next.

Just to give you an idea of what this is, below is a basic directory structure. Within the directory “test” is about 600 subdirectories

/disk/building/test/
/19587
/245
/89578
/87597
/ect ect ect

Thanks in Advance!!!

I've written this as a start, but it doesn't want to work:

------------------------------------------------------
#!/usr/bin/sh

for myfile in `ls`; do
if [ -d $myfile ] ; then
echo "Working on directory : $myfile"
# resize *.img .....
fi
done
------------------------------------------------------

Any hints???

The script doesn't do anything. If I change the script as follows this is what I get:

script:
------------------------------------------------------
#!/usr/bin/sh

echo "Start"
for myfile in `ls`; do
if [ -d $myfile ] ; then
echo "Working on directory : $myfile"
# resize *.img .....
fi
done
echo "finish"
------------------------------------------------------


output:
------------------------------------------------------
Start
Finish
------------------------------------------------------

Besides actually looking to make sure the files were not "resized" the resize command echo's several lines while it is working.

The appropriate subdirectories exist, the appropriate files are in them and the command works, but the script doesn't actually do anything other than echo those two words. I suppose I should try something different but i am not a UNIX person and am not too familiar with the coding.

thanks,

CzarJ

Depending of your current directory, you may consider add this line after echo "Start":
cd /disk/building/test

find /disk/building/test -type d -print | grep -v ARCHIVED >> "${PLINE}"

cat "${PLINE}" | while read wrkDir
do

cd $wrkDir
if [ "`pwd`" = "${wrkDir}" ]; then

RESIZE HERE
