I want to build a script to convert any *.png files to *.jpg files using
convert.
Doing manually works fine.
Building a script has presented problem. I am well versed in programming
but a novice with bash.
My loop through the files works fine.
#!/bin/bash
cd /big1/memes/;
shopt -s nullglob
for f in "*.png"
do
echo $f
done
I get a list of filenames with an extension of .png
But when I try to get the basename with:
#!/bin/bash
cd /big1/memes/;
shopt -s nullglob
for f in "*.png"
do
echo $f
b=${f%.png}
echo $b
done
I first get a list of the .png files, then a list of all files, both the
existing .jog and the .png. This gets a WTF reaction from me.
Can someone explain and help me get closer to getting this to work?
Thanks
