shell command to find a process id and attach to it?

Question

I want to attach to a running process using \'ffffd\', what I manually do is:

# ps -ax | grep PROCESS_NAME

Then I get a list and the pid, the

Answer 1

There is an easy way to get rid of the grep process:

ps -ax | grep PROCESS_NAME | grep -v ' grep '

(as long as the process you're trying to find doesn't include the string " grep ").

So something like this should work in a script (again, assuming there's only one copy running):

pid=$(ps -ax | grep $1 | grep -v ' grep ' | awk '{print $1}')
ffffd $1 ${pid}

If you call your script ffffdproc, you can call it with:

ffffdproc myprogramname

Although I'd add some sanity checks such as detecting if there's zero or more than one process returned from ps and ensuring the user supplies an argument.
