Upload awk variable to shell

My colleague asked me a question about awk today. It means that the several rows of data obtained through the awk operation are not fixed. You need to store the obtained rows of data in an array and do not want to use loops. After one afternoon's efforts. Finally.

Final line eval $ (ps-ef | grep tomcat | awk '{print $9}' | sed '/home /! D' | sed's/^. * home \ // G' | sed's /\/. * $ // G' | awk '{printf "line [" NR "] = % s \ n", $1 }').

Note: 1. assign values to variables in awk. If eval $ () is not used, variables in awk cannot be used in shell. 2. awk has parameters such as NR and NF, which can be used to generate an array.
