How to concatenate 2 files using awk?

I have to select a field ($8) from file1, then add an entry to the file2 in the correct format:

/tmp> cat file1
3001-233 Invalid admin value in /etc/security/group for "imnadm"
3001-233 Invalid admin value in /etc/security/group for "perfmon"
3001-233 Invalid admin value in /etc/security/group for "extract"
3001-233 Invalid admin value in /etc/security/group for "vality"
3001-233 Invalid admin value in /etc/security/group for "profadm"
3001-233 Invalid admin value in /etc/security/group for "db2asgrp"
3001-233 Invalid admin value in /etc/security/group for "db2adm"

/tmp> cat file2
system:
admin = true
staff:
admin = false
bin:
admin = true

Any ideas?

Thanks.

This should work:

{ cat file1.txt  | cut -d " " -f 8; cat file2.txt; }

Note: The semi-colon and space before the closing curly-brace are both required.

Thanks Shawn! I'll try that.
