I guess this has been posted hundred times,  but my search string show
me trheads i don't understand.

need to extract  the fields after a match,  could be any position,
discard future equal string.

let me explain.

infile.txt
str1 str2 str3 str4  err003 str5 str...N
str1 str2 str3 str4  str5 err002 str5 str...N
str1 str2 err003 str3 str...N
str1 str2 str3  err002 str4 str...N

so I must search  /err[1-9]/   and grab the subsequents fields. but if
I find the same err# discard it.

the desire output will be.

err002 str# str#+1   they are erros so is the same text after
err003 str# str#+1

once Ed show me

awk 'c&&c--;/pattern/{c=N}' file   but I did not understand, I did'nt
want to bother him , to wait to reach the desire level on awk, haven't
get there , but need to do this..

Thanks.

discard the first occurence you found, or ignore subsequent occurences you find?

that would've been much more useful if you'd shown the desired output given the
input you posted.

That's the solution to a totally different problem.

Sorry Ed for not being clear.

having a file like the infile above, I want to search for a pattern
"err" that could be on any position,  take all the fields after this
field, including it.  and as you said ignore subsequent occurences of
the patterm i've found.

The desired output will be.
err003 str5 str...N     I mean the field that match and all
subsequents fields
err002 str5 str...N

again sorry for including the hint you gave me before, I get lost
trying to figure out an approach.

PD.  one last tihng , how do I trim the pattern from the field.?   I
mean the field is "err003" I look for the pattern "err"  but what I
want is "003" for the output

awk '
   match($0,/err[0-9]+/) { e=substr($0,RSTART,RLENGTH) }
   !(e in err) { err[e]; print substr($0,RSTART+3) }
