[SOLVED] for loop and space character in names

salmanahmed · 12-29-2022, 08:59 AM

Hi
I am trying to convert a large number of JPG files into PNG. For this purpose I tried "for" loop as follows:

Code:

for i in *.jpg;do convert $i $i.png;done

This commands works fine for all files, except for those which contains spaces in their names. For example, if a file is named as "my picture.jpg", then "convert" or any other utility gives following error:

Quote:

convert: unable to open image 'my': No such file or directory
convert: unable to open image 'picture.jpg': No such file or directory

So, what change I should make in this "for" loop to accommodate files with space character in their names?
Thanks

try this:

Code:

for i in *.jpg;do convert "$i" "$i.png";done

Oh my... Why didn't I think of such an obvious solution

Thanks a lot

A modifier chops off the old extension:

Code:

convert "$i" "${i%.*}.png"

The code in your top post would work as-is if you use ZSH.
