So here is similar one liners but ...
awk '{ print $3 }' # extract third field separated by space
awk -F'\t' '{ print $3 }' # extract third field separated by tab
awk -F'\t' '($3=="111")'
perl -ne 'print if (split('\t'))[2]==111'
# extract lines where third field is "111" separated by tab
awk '($2=="1957") { print $3 }'
# extract third field where the second field is "1957"
For the last awk, I can not do the same with perl one liner.
I will add these to "Debian Reference", Chapter 8, tips.
Any one?
