tips, combining strace with pidof

[Masatake YAMATO]

Hi,

I guess you, enjyoing hacking strace, may use strace with pidof like:

  # strace -p $(pidof httpd)

As you may know, this doesn't work if there is more that one http process.

I have been frustrated with this for years.
Though who are the same, let's wait the new release of procps.
I added an option to specify the separator. You can run strace like:

  # strace -p $(pidof -S ' -p ' httpd)
