Curious which man-pages on my FreeBSD system were most overloaded:

$ find /usr/local/share/man/ /usr/share/man -type f | sort | awk -F/ '{sub(/\.[^.]*\.gz$/, "", $NF); t=$NF; sec=$(NF-1); k=t SUBSEP sec; if (!(k in seen)){seen[k]; a[t]++ ;s[t] = s[t] " " sec}} END{for (k in a) if (a[k]>1) print a[k], k, s[k]}' | sort -nr | head -5
10 intro man1 man2 man3 man3lua man4 man5 man6 man7 man8 man9
4 random man3 man4 man6 man9
4 jail man2 man3 man3lua man8
4 hash man1 man3 man3lua man9
4 cpuset man1 man2 man3 man9

I should have known intro(n) would have the most, but was interested to see that random(n), jail(n), hash(n) and cpuset(n) all appeared in multiple man-page sections.
