[Solved] Converting pdf to jpg in multiple directories?

martinsmith · #1 01-12-2013

Hi!

On my Ubuntu I have thousands of files in a couple hundred directories. I'm trying to convert the pdf's to jpg's.

I used this command in terminal:

Code:

for fname in *.pdf; do convert $fname ${fname%.pdf}.jpg; done

It works great but the problem is I have to run this in terminal for each folder/directory so it's time consuming.

Is it possible to covert all the pdf's in the sub directories from the root directory at once in terminal?

Thanks for your help

Hi,

use find - you can traverse your directories with it, and even start your conversion per each file found. There are more efficient methods, but this depends on the amount of the files you have. Have a look at the manual page of find(1), but one way to accomplish your target would be something like:

Code:

find the_root_directory_of_pdfs -name \*.pdf -exec convert \{\} \{\}.jpg \;

Code:

find root_of_pdfs -name \*.pdf | while read fname; do convert $fname ${fname%.pdf}.jpg; done

Hi Pen,

Yes Thanks you this is exactly what I needed!

It's worked perfectly after testing and done the conversion of all the pdf files to jpg.

Thanks very much for your help, I appreciate it!
