Hello. #?0|kent:roff.git$ AWK=nawk dash mdocmx.sh mdocmx.1|wc -l 137 #?0|kent:roff.git$ AWK=gawk dash mdocmx.sh mdocmx.1|wc -l 137 #?0|kent:roff.git$ AWK="/home/steffen/usr-kent-linux-x86_64/bin/busybox awk" dash mdocmx.sh mdocmx.1|wc -l 27 I do not know anything else. All i can say is that END{} normally executes, but then new busybox awk stops. Maybe a descriptor is closed?
