Good day, I have a centos 4.4 box (all yumed up). Now i have a program that has a sub shell - meaning something like the mysql command line, where once started it takes it's own commands, etc and keeps running until a "quit" command is issued. Now what I was wondering - is there a way to fork it to the background (something like # command & or ctrl -z) and have the subshell keep running? And also to be able to get back to the sub shell? For example, if i do run it with the & at the end it does what I want, yet obviously (to my knowledge) you can't get back to the subshell without killing it and restarting it. I have looked into the "screen" shell utility, which for the most part does what I needed, however after a few days the session had disappeared and I was not able to get back to it from another machine/ssh session. Are there any other options? Thanks! Dustin
