Allow Okular to reload previously open files

This may help some folks who want to use Okular but also have their PDF files reopen between restarts. You can call saveokular.sh from cron and some other tricks so this is all seamless:

$ cat /usr/local/bin/openokular.sh

#!/bin/bash

Check if the file with paths exists

if [ ! -f ~/.okular_open_files.txt ]; then

echo "No saved PDF paths found."

exit 1

fi

Open PDFs in Okular

echo $1 >> ~/.okular_open_files.txt

sed -i '/^$/d' ~/.okular_open_files.txt

cat ~/.okular_open_files.txt | xargs -d '\n' /usr/bin/orig_okular &

$ cat /usr/local/bin/saveokular.sh

#!/bin/bash

if pid=$(ps -C orig_okular -o pid= | sed -e 's/\s//g') && [[ -n $pid ]]; then

ls -l /proc/"$pid"/fd | grep '.pdf' | awk -F ' -> ' '{print $2}' > ~/.okular_open_files.txt

fi
