Ubuntu sometimes use the man xxx query function can not find the solution __ function

This is because man doc is incomplete.

For example, after installing Ubuntu, I learned about the UNIX network programming volume for a while, when I used the pthread_mutexattr_setpshared to use the man query.

Searched the next online.

Install the following two packages, the basic function can be traced to the

sudo apt-get install Glibc-doc

sudo apt-get install Manpages-posix-dev

If you still have a query, you can search for that function first in the http://manpages.ubuntu.com/.

Then the top of the page says:

Hardy (3) pthread_mutexattr_setpshared.3posix.gz
Provided By:manpages-posix-dev_2.16-1_all

Then use sudo apt-get install Manpages-posix-dev OK. Multi-Tab complement

I found it again,

Install sudo apt-get install Manpages-zh and then

Use the man to query the common commands when the inside is Chinese ... (Not all Chinese)

such as Man LS, mans grep and so on.
