grep 'dependency-name' /usr/ports/INDEX.8 | grep -v '^dependency-name'
If you don't want the whole INDEX line, add something like this to the
above to extract specific columns:
| cut -d '|' -f 1
Note that you want the dependency package name, not the directory name
in the ports tree -- although most of the time they are the same, there
are some important packages where that isn't the case, eg.
databases/mysql51-server vs mysql-server-5.1.48
Actually, all you want is sufficient leading prefix from the package
name to identify it uniquely, which usually, but not always, means you
don't need to include the version number part
This will include build dependencies as well as run- or lib-
dependencies: if that's not what you want, then use cut(1) to get rid of
the last two columns before passing the INDEX through grep(1)
Cheers,
Matthew
