Ensures that you don't lose your konsole sessions when you crash/ reboot Linux

dont-lose-konsole-terminal-sessions-on-reboot.md

Usage

• Save the two files below. I put them in '~/.scripts'
• Modify the configuration in konsole-watcher.sh to your liking
• Modify the location of konsole-watcher.sh in konsole-watcher-autostart.sh if you chose to put it somewhere besides ~/.scripts
• Create the directory ~/.konsole (or other location you chose for the save file)
• Create a symlink to konsole-watcher-autostart.sh in '~/.config/autostart-scripts
• or open System Settings > Startup and Shutdown and add a script to the Script Files (it does the same thing as creating the symlink)
• You might want to add a menu entry as well in case KDE autostart doesn't work for some reason

Problem that it solves

• Automatically saves your current Konsole sessions with their working directories every 15 seconds (or other default you set)
• Automatically starts Konsole when you log in with tabs for each or the sessions you had open previously

       done
    fi
}

#Update the Konsole sessions every WATCH_INTERVAL_SECONDS seconds
while true; do sleep ${WATCH_INTERVAL_SECONDS}; getSessions; done &

Updated konsole-watcher.sh so it doesn't overwrite the file when there are no konsole sessions running and added a date to the file comment.
