I am using FreeBSD 8.1.
I am doing some automation stuff and running shell scripts remotely using
setsid command.
It seems that I do not have setsid on my system. Also, searched in
/usr/ports for installation but no luck.
Could you please tell me the way to install this command or may be the
alternative?
I used a very simple implementation in one of my ports.
/usr/ports/net/nxproxy/files/setsid.c

Yeah it is not very hard to grab the source yourself and do a little
modification.
gcc -O2 -o setsid setsid.c
modified for your enjoyment...
