I've slightly modified the code you gave me to add a little extra logic
in determining
when it should do the image conversion. It will also remove a
cover.png file that
exists in the same folder that a cover.jpg is in, leaving just the .jpg
version.
Code:
--------------------
#!/bin/sh
traverse()
{
# Traverse a directory
cd "$1"
if [ -s "cover.png" ]; then
if [ ! -s "cover.jpg" ]; then
pngtopnm cover.png | pnmtojpeg > cover.jpg
else
/bin/rm -f cover.png
fi
fi
ls | while read i
do
if [ -d "$i" ]; then
echo "Directory: $i"
# Calling this as a subshell means that when the called
# function changes directory, it will not affect our
# current working directory
(traverse "$i" `expr $2 + 1`)
fi
done
}
if [ -z "$1" ]; then
traverse . 0
else
traverse "$1" 0
fi
--------------------
Thanks a lot for your pointer in this area as it seems to be working
well.
I am still curious, however, if this conversion should be necessary.
Does
anyone have an opinion on this?
