Omitting certain columns

[segment]

I have a line sometimes it has 10 columns sometimes it can go to 30 columns... I need everything except fields 3, 4 and 5. Couldn't find an exisiting solution in these archives nor googling... Thanks

perl -e 'print $i=pack(c5,(40*2),sqrt(7600),(unpack(c,Q)-3+1+3+3-7),oct(104),10,oct(101));'

Hi

awk '{for(i=6;i<=NF;i++)$(i-3)=$i;NF-=3}1' /input/file

Tested with [tt]gawk[/tt] and [tt]mawk[/tt].

cut -d' ' -f 1,2,6-, presuming space is your field separator. Of course there would be an awk solution, but cut is much simpler.

And talking of the awk solution, there it is!

If whitespace is the field separator, why not simply null out the fields you don't want:

awk ' { $3=$4=$5=""; print } ' infile
