 |
|
Trying to display java-config man page:
| Code: | $ qlist java-config | grep man
/usr/share/man/man1/java-config-2.1.bz |
| Code: | $ man java-config
No manual entry for java-config |
Any idea?

Just do:
| Code: | | $ man -u java-config |
To rebuild the database for java-config.

You are right, that's it.
But how to find out if you don't know? Is there kind of command listing the available man pages? |

You can use the "apropos" to find, like:
By the way: my "$ man java-config" still works fine.

As ff11 say you can use apropos . or man -k .
In my case I use bash-completion (or zsh-completion) so when I write man and double <tab> the list is showed

And then finally: | Code: | $ apropos java
java-config-2 (1) - The Java configuration tool for Gentoo
node (1) - server-side JavaScript runtime
npm (1) - javascript package manager
npm-README (1) - a JavaScript package manager
registry (7) - The JavaScript Package Registry |
And also man java-config without trailing number works here (again).
Thanks for your help |

Good to know. But I have to inform you about something:
The normal user get the man database updates from cron daily tasks (https://wiki.gentoo.org/wiki/Cron) in "/etc/cron.daily/man-db".
Then, if you aren't running it, you will need to do manual updates from time to time (if you need updates, of couse).

No cron here. I was expecting the man stuff to be updated by @world updates. What's wrong with it? |

Because it take forever for each package that need it. The pacman on ArchLinux do this, but a lot of users don't like it. The Gentoo (and ubuntu...) do using "nice" background cron daily tasks (the normal users feel less pain that way).
I myself, just update it when I need it, I don't use man pages everyday, and I only need updates like one per year.

Because the normal working linux installation use cron, and "sys-apps/man-db" install the task "/etc/cron.daily/man-db", then the users don't need to do nothing for it to work.
The users that don't want that task, will just remove it (but taking note of why).
But if you don't use cron, then you have to know everything that need to be running, not only mandb, but others things like logrotate (or someday you will have problems with "/var/log/" size)
Again, I myself have "sys-process/cronie" installed, but not running. And I just take a look on the tasks (/etc/cron*), that I make one manual run when I need it.
