i've written bash scripts, beyond me , have no idea start. i'm running xubuntu. i'm using vpn allows me have forwarded port forwarded, running following line, produces output below, different port each time.
command: ./port_forward.sh user password output: loading port forward assignment information.. {"port:58661} i'm looking make script runs process, takes port output, , puts configuration file deluge, , runs deluge. i've pasted current configuration below, 2 instances of 32157 need changed new port. file located @ /home/user/.config/deluge/core.conf

eta:
thanks! wasn't quite sure how meant i'd new port, came this:
#!/bin/bash oldport=`cat core.conf | grep -a2 listen_ports | tail -n1` a=$(~/port_forward.sh user password) b=$(echo -e "$a" | sed -n '2p') port=`echo $b| cut -c9-13` sed -i 's/'$oldport'/'$port'/g' "core.conf" deluge-gtk %u it works, though i'm there cleaner ways it. interested if there's way take whatever 5 digit number contained in output of port_forward.sh command , make variable. have above not ideal , break if output changed @ all. , yes, have 1 double quote, no idea why.
eta2: never mind, figured out. again help!
#!/bin/bash oldport=`cat core.conf | grep -a2 listen_ports | tail -n1` port=$(~/port_forward.sh user password| grep -o "[0-9][0-9][0-9][0-9][0-9]") sed -i 's/'$oldport'/'$port'/g' "core.conf" deluge-gtk %u
you can clean bit using parameter expansion/substring extraction. give following try. eliminates numerous 3rd party app calls along subshells spawn. don't have port_forward.sh script test exact output, following should work based on have posted:
#!/bin/bash oldport=`grep -a2 listen_ports core.conf | tail -n1` a=$(~/port_forward.sh user password) tmp=${a##*port:} port=${tmp%\}*} sed -i 's/'$oldport'/'$port'/g' "core.conf" deluge-gtk %u note how rearranged oldport line. try , avoid uuoc (unnecessary use of cat). if ever find doing cat |, should tell there more appropriate way it. giving filename directly, using redirection, or use of herestring, or redirecting output of subshell... takes practice.
