UnrealIRCd Forums

In the event of a crash/shutdown, does Unreal remove the ircd.pid file from it's directory, or does it stay until the next start? I'm writing a small shell script to check whether or not the IRCd is running so it would be helpful to know what happens to the file. Thanks.

Well, if Unreal crashes, there is no way for it to do anything (it's dead) so no, it won't delete the file. The standard way to test if a process is running (as can be seen in the chkircd script) is to send it a SIGCHLD

I see, thanks. I'm looking at the chkircd script and I have two questions if someone wouldn't mind.

First, is there an advantage to using the "test -r" command to see if the pid file exists over merely using the -e switch with if?

Second, in the line: What does the 2>&1 do at the end there?

This is UnrealIRCd support, not shell scripting. If you need help with shell scripting, I'd suggest you use Google. A quick search answered both of your questions
