MKFIFO(1) BSD General Commands Manual MKFIFO(1)
NAME
mkfifo -- make fifos
SYNOPSIS
mkfifo [-m mode] fifo_name ...
DESCRIPTION
The mkfifo 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 mkfifo utility
requires write permission in the parent directory.
DIAGNOSTICS
The mkfifo utility exits 0 on success, and >0 if an error occurs.
STANDARDS
The mkfifo utility is expected to be IEEE Std 1003.2 (``POSIX.2'') compliant.
SEE ALSO
mkdir(1), rm(1), mkfifo(2), mknod(2), mknod(8)
HISTORY
The mkfifo command appeared in 4.4BSD.
BSD
January 5, 1994 BSD
