Recover a running script from a terminal session
look for the script's pid using ps
ps -ef|grep script.sh
Fdo 8983 8463 0 12:28 pts/2 00:00:00 /bin/bash ./script.sh
check /proc/$PID/fd/; there should be a broken link to the script file, but cat should work (while the script is running!):
cat /proc/8983/fd/255
#!/bin/bash
# script contents!
good luck!
