I have a serious problem about daemonizing my script ( an executable, I named it as myScript at below ). I use standart template ( Centos 5.9 ) but due to a problem I could not figure out the reason, after random time it fails to start, and since I made it in while loop it restarts forever. For example, it works 2-3 hours, then it fails and begins to restart, or it fails at the first try and restarts forever...
And another thing is, I have a second script ( named it as mySecondScript at below ) and while I start them ( second script first, then the first script ) there is no problem, but while stopping them, first script fails to stop ( because of killing process or removing pid ), what should I change in process catching line, thanks in advance.
It is nice if a daemon has 1 as parent, by a killed parent shell. But a true daemon should not be in an interactive process group or related to a controlling terminal, so I often launched mine with at, crontab (auto restart as a bonus) or an ssh nohup that kills ssh after the nohup, or off an xtern that I then kill. Of course, it you have root you can have init.d or some daemon manager like src launch it for you on boot.
I used to lose my Xserver's mwm from ctrl-c SIGINT on the launching xterm; drove me nuts until I used the first xterm to launch everything and then killed it, making them all orphans, or devoted it to top.
I don't know if you guys get this problem sometimes at Terminal but I had been having this problem since yesterday :( Maybe I overdid the Terminal. Even the codes that used to work doesn't work anymore.

2-Redirecting STDIN, STDOUT and STERR
3-Using nohup command to make script not being interrupted by hang up signal... (5 Replies)
