mkfifo — Make a FIFO special file
Format
Description
Options
mkfifo [–m mode] file [–p]
mkfifo creates one or more FIFO special files with the given names.
mkdir
–m mode
Lets you specify file permissions for the files. The mode argument can have
the same value as the mode argument for chmod; see chmod for more
details.
–p Creates intermediate directory components that do not already exist. For
example, if one of the file arguments is dir/subdir/file and if subdir does
not exist already, this option creates it. Such intermediate directories are
created with mode bits determined in the following way: Take a default
mode setting 777 (a=rwx), apply the umask setting of the process to it, and
then turn on user read, write, and user execute permissions (u+rwx).
