That's not good enough for scripting. First of all, the command is not so simple (you have to grep -v grep also - so that the same script works on Unix systems) and if you have small PID number like 14, that will likely return lots of other processes (like 114, etc). Also, the same <PID> appears in the PPID column if it has children. Some Unix variants might not have a space in the ps output between the PID and previous or next column when one of the column's data is larger than the specified printf format.
So your command is not reliable enough for scripting and is also very slow on large Unix systems with 1000's of processes running. ps -p <PID> is immediate, reliable, and portable (it's SYSV/SVR4 standard). -Don > -----Original Message----- > From: Carlo Florendo [mailto:[EMAIL PROTECTED] > Sent: Wednesday, July 27, 2005 5:22 PM > To: Don Beusee > Cc: cygwin@cygwin.com > Subject: Re: ps -p <pid> > > Don Beusee wrote: > > >Can you add the -p <pid> option?
