awk/grep question

Asked by kkatula in Shell Scripting, Bourne Shell (sh), Unix Systems Programming

I have a Unix script that I need to parse a data file and kick out any line where the 4th field has less than 15 characters. I have this which works fine until there are no lines that need to be kicked out.  When every line has a field 4 with at least 15 characters, the grep below yields a zero byte file.  Any ideas?

awk -F"|", 'length($4)<15' /tmp/listfinal >> /tmp/deleteme
/usr/xpg4/bin/grep -v -f /tmp/deleteme /tmp/listfinal > /tmp/listclean
