Thank you all. I didnt mention the language, yes, I wanted it with
shell script. Sadly, no idea was completly enough, for the default ps
output it simple has no pattern. No multiple-pattern would do the job
safely. With kernel stuff like idle, output happens to be completly
nonsense. Counting positions in a array is the way to go, but not with
the default output. Things just happen to get completly trashed with
long values, like idle CPU time.

What I did was formating every output header like that

ps -o start="<<<..............................................>>>" -o
lstart="<<<..............................................>>>" -o
args="<<<..............................................>>>" etc

So I could find the begining and the ending column. "-o command" or
"-o args" have always to be the last option, if I dont want 'em to get
truncated.

So sad.

Now my next problem, do the sabe with sockstat....

%sockstat | head -4
USER COMMAND PID FD PROTO LOCAL ADDRESS FOREIGN ADDRESS
freebsdsupportsshd 57255 3 tcp4 172.16.0.225:22 172.16.0.69:63583
freebsdsupportsshd 57255 4 stream -> ??
root sshd 57253 3 tcp4 172.16.0.225:22 172.16.0.69:63583

So I have the USER and COMMAND column "merged" in a single string,
because username is large. Again, space can not be used as a
separator, but hopefully only the patterns with "->" will have space
if not a column separator, easier to parse.

But sockstat have no formatting option to be issued like -o from
ps(1). Measing in the very first sockstat output, I dont know what to
do...
