NetBSD cromarty 1.4X NetBSD 1.4X (CROMARTY) #9: Wed May  3 23:49:51 BST 2000

>Description:
According to POSIX.2, the -p, -t and -U options to ps should all take
blank- or colon-separated lists of values as arguments.  None of them
does.

>How-To-Repeat:
cromarty:~$ ps -p 1,2,3
ps: proc size mismatch (776 total, 696 chunks).
Warning:  /proc does not provide valid data for all fields.
  PID TT  STAT      TIME COMMAND
    1 ??  ?<s    0:00.69 init 
cromarty:~$ ps -p 2,3
ps: proc size mismatch (776 total, 696 chunks).
Warning:  /proc does not provide valid data for all fields.
  PID TT  STAT      TIME COMMAND
    2 ??  ?<s+   0:00.19 (usb0)
cromarty:~$ ps -U root,bjh21
ps: root,bjh21: illegal user name
cromarty:~$ ps -t 'p0 p1'
ps: /dev/ttyp0 p1: No such file or directory
