Merge multiple jpg into single pdf in Linux

Question

I used the following command to convert and merge all the jpg files in a directory to a single pdf file.

convert *.jpg file.pdf 

The files in the directory are numbered from 1.jpg to 123.jpg. The convertion went fine but after converting the pages were all mixed up. I wanted the pdf to have pages from 1.jpg to 123.jpg in the same order as they are named. I tried with the following command as well:

cd 1  FILES=$( find . -type f -name "*jpg" | cut -d/ -f 2) mkdir temp && cd temp  for file in $FILES; do      BASE=$(echo $file | sed 's/.jpg//g');     convert ../$BASE.jpg $BASE.pdf;      done &&  pdftk *pdf cat output ../1.pdf &&  cd ..  rm -rf temp 

But still no luck. Operating platform Linux.

Answer 1

Or just read the ls manual and see :

-v natural sort of (version) numbers within text

So, doing what we need in single command.

convert `ls -v *.jpg` foobar.pdf 

Have fun ;) F.
