| | | | | | | when copying per-process info before starting to sort the list. This way, sort-by-CPU or sort-by-memory will only calculate values once-per-process, instead of twice-per-comparison. Also take advantage of this to simplify the pscomp() routine.

| | | | | | | | | | | | | have no entries to print (either due to an empty directory or an error). This makes the -l and -s options more consistent, like Solaris and (Debian) Linux. To make this happen, tweak two optimizations on the second call to display(): - Don't skip display() altogether, even if list == NULL. - Don't skip the call to the printfn in display() if we need to print the total.

* Rewrite the kludge-option processing to improve how it handles a fewgad2004-06-011-62/+91
| | | | | | | | | | | | | | | | | | | | more special situations. This is the code which process `ps blah', when "blah" does not include a leading '-'. This change also removes a long-undocumented BACKWARD_COMPATIBILITY compile-time option, where: ps -options arg1 arg2 (with no '-' on "arg1" and "arg2") was treated as: ps -options -N arg1 -M arg2 This also changes `ps' to check for any additional arguments after processing all the '-'-options, and attempt to use those arguments as a pid or pidlist. If an extra argument is not a valid pidlist, then `ps' will print an error and exit. This seems a more generally useful extension of the kludge-option processing than the -N/-M behavior, and has fewer confusing side-effects. Reviewed by: freebsd-arch
