I ran this on a Debian i386:

dione$ cd /usr/bin
dione$ for CMD in ? ?? ??? ???? ?????; do OUTPUT="`man $CMD 2> /dev/null | col -b | egrep -- '^[ \t]*-n[ \t,].*'`" && echo -e "$CMD:\t$OUTPUT"; done

The results - filtered for the ones where '-n' meant 'pretend/simulate'
- were as follows:

gpg: -n, --dry-run
lex: -n is another do-nothing, deprecated option included
flex: -n is another do-nothing, deprecated option included
make: -n Print the commands that would be executed, but do not
tcsh: -n The shell parses commands but does not execute them.
eject: -n With this option the selected device is displayed but
rsync: -n, --dry-run show what would have been transferred
skill: -n no action This only displays the process ID.
snice: -n no action This only displays the process ID.
xmake: -n dry run - do not execute commands lists

Sure, there are many more non-pretend '-n's than there are pretend ones,
but '-n' seems to mean 'pretend' more than any other single meaning.
Whether that makes it a convention or not ...
