Hello I have a file like :
20120918000001413 | 1.17.163.89 | iSelfcare | MSISDN | N
20120918000001806 | 1.33.27.100 | iSelfcare | 5564 | N
....
I want to extract all lines that have on 4th field (considering "|" the separator ) something other than just digits. I want to do this using a awk one-liner ( I don;t want shell commands because combination of grep, while, cut.. etc takes way too much time)
I have this command :
awk -F'|' '$4 == " [A-Z]* "' target_file.txt
But it doesn't work.
