Awk Null Field

by Gary Hanley

Wow, what's wrong with me? I'm trying to parse a file to eliminate any line from the file to the output where a particular field is is null. The 8th field in this case. I can't get it right! I haven't done an awk script in a long time but this should be simple stuff. Basically I'm trying to do: cat file | awk -F\| '$8 !~ <NULL expression> {print}' Any help would be appreciated. Thanks. -- Gary
