I never needed this, so I don't know how to do it directly with emerge |
| 30 |
(is it possible?), but you can use equery like this to get a list: |
| 31 |
|
| 32 |
equery -q d dev-lang/go |
| 33 |
|
| 34 |
-q/--quiet (minimal output) |
| 35 |
(d)epends (list all packages directly depending on ATOM) |
| 36 |
|
| 37 |
to get a list of packages installed which depend on dev-lang/go |
| 38 |
you can filter versions out of it and feed that to 'emerge -av1'. |
| 39 |
|
| 40 |
Or if you trust this ugly one-liner without filtering (probably ugliest |
| 41 |
thing, but seems to do the job): |
| 42 |
|
| 43 |
emerge -av1 $(for i in $(equery -q d sys-apps/util-linux); do echo |
| 44 |
"=$i"; done) |
