/proc/pid/cmdline usually has ASCII NUL separated fields, which awk does

some way. It doesn't by default.
Ok, I didn't know that. Thank you for the explication
awk -F '\000' '{print $1;exit}' /proc/$pid/cmdline
That depends on whether you're using gawk (which provides a non-POSIX
extension for nulls), or mawk.
fwiw, this example works with current mawk - here:

however, Debian's packagage maintainer for mawk has not responded to any
of the fixes which I've made over the past year.
