grep and put the SL no - AWK Newbie
The purpose is very simple, I had to find all people names(1st field) from location(3rd field) "Ind", with a SL No in beginning. i.e. if the input files are like this:
$ cat file1.txt
Hanr:3232:Ind:/tmp/da02.out
Ajith:2211:Ind:/opt/ds.out
Rein:2221:Jpn:/tmp/ls.out
Leela:1198:Ind:/
$ cat file2.txt
Olea:5454:Swd:/opt/ert.tmp
Lola:2129:Chn:/home/Lola
Nina:8784:Ind:/opt/ls.out
Rahim:6551:Ind:/tmp/as.out
The output required is :
1 Hanr
2 Ajith
3 Leela
4 Nina
5 Rahim
Here is the solution:
$ awk -F ":" '$3=="Ind" {c++;print c,$1}' file1.txt file2.txt
