mkfifo - make FIFO special file
SYNOPSIS
/usr/bin/mkfifo
[
-m mode
]
path...
AVAILABILITY
SUNWesu
DESCRIPTION
The
mkfifo
command creates the
FIFO
special files named by its argument list.
The arguments are taken sequentially, in the order specified; and each
FIFO
special file is either created completely or,
in the case of an error or signal, not created at all.
If errors are encountered in creating one of the special files,
mkfifo writes a diagnostic message to the standard error
and continues with the remaining arguments, if any.
The mkfifo command calls the library routine
mkfifo.3c
with the
path
argument is passed as the
path
argument from the command line, and
mode
is set to the equivalent of
a=rw,
modified by the current value of the file mode creation mask
umask.1
OPTIONS
The following option is supported:
- -m mode
-
Set the file permission bits of
the newly-created
FIFO
to the specified
mode
value. The
mode
option-argument will be the same as the
mode
operand defined for the
chmod.1
command. In
<symbolicmode>
strings, the
op
characters
+
and
-
will be interpreted relative to
an assumed initial mode of
a=rw.
OPERANDS

- file
-
A path name of the
FIFO
special file to be created.
