Other Manual Entry Collections
These manual pages are from the machine albeniz
which runs Linux 4.9.0-0.bpo.12-amd64
Some information contained in man pages is specific to the
architecture and OS version. The appropriate man page is displayed
depending on the architecture and OS of the machine on which the man
cammand is run. For example, some system calls vary in such a
fashion. Therefore, if you are looking up this kind of information
you will need to run the man command on a machine of the appropriate
architecture and OS version. If this happens to be the same as that
listed above then you need look no further.
