The
utility creates the fifos requested, in the order specified.
The options are as follows:
-m
Set the file permission bits of the created fifos to the
specified mode, ignoring the
umask(2)
of the calling process.
The
mode
argument takes any format that can be specified to the
chmod(1)
command.
If a symbolic mode is specified, the op symbols
`+'
(plus) and
`-'
(hyphen) are interpreted relative to an assumed initial mode of
``a=rw
''
(read and write permissions for all).
If the
-m
option is not specified, fifos are created with mode
0666
modified by the
umask(2)
of the calling process.
The
utility requires write permission in the parent directory.
