This is because we are discussing problems in 2.1.14 script execution.
Scripts now show up in the ps listing by the interpreter that is running
the script, not by the name of the script. This behavior is DIFFERENT than
the behavior of previous kernels. The behavior of ps is quite inconsistant
even between different UN*X flavors, as shown below. I personally liked
the old behavior, since it worked nicely to kill scripts with "killall
foo". I think the old behavior should be reimplemented, and a patch to
reimplement it was already posted to linux-kernel.

Linux 2.0.27:
andersee@Dillweed% ps
4335 p1 S 0:00 bash ./scum
andersee@Dillweed% ps -c
PID TT STAT TIME COMMAND
4335 p1 S 0:00 scum

Linux 2.1.14:
andersee@Dillweed% ps
PID TT STAT TIME COMMAND
279 p0 S 0:00 bash ./scum
andersee@Dillweed% ps -c
PID TT STAT TIME COMMAND
279 p0 S 0:00 bash

IRIX:
andersee@sulu% ps
PID TTY TIME COMD
819 ttyq0 0:00 scum
andersee@sulu% ps -f
UID PID PPID C STIME TTY TIME COMD
andersee 819 802 0 13:39:28 ttyq0 0:00 /bin/sh scum

HP-UX:
andersee@kansas% ps

andersee@kansas% ps -f
UID PID PPID C STIME TTY TIME COMMAND
andersee 7724 7642 0 12:54:25 ttyp4 0:00 scum ./scum

AIX:
