This one-liner will use strace to attach to all of the currently running apache processes output and piped from the initial "ps auxw" command into some awk.
There are 5 alternatives - vote for the best!
Like the original version except it does not include the parent apache process or the grep process and adds "sudo" so it can be run by user.
Especially for sysadmins when they don't want to waste time to add -p flag on the N processes of a processname.
In the old school, you did ;
and typing strace -f -p 456 -p 678 -p 974...
You can add -f argument to the function. That way, the function will deal with pgrep to match the command-line.
processname -f jrockit
This version also attaches to new processes forked by the parent apache process. That way you can trace all current and *future* apache processes.
If you can do better, submit your command here.
