If your macOS isn't up to date, you may be able to update to a later version.
Which macOS version is installed?
From the Apple menu in the corner of your screen, choose About This Mac. You should see the macOS name, such as macOS Big Sur, followed by its version number. If you need to know the build number as well, click the version number to see it.
Which macOS version is the latest?
These are all Mac operating systems, starting with the most recent. When a major new macOS is released, it gets a new name, such as macOS Big Sur. As updates that change the macOS version number become available, this article is updated to show the latest version of that macOS.

I should note that the last example really needs 3 sessions.2 running
tail -f pipeand another running
cat > pipetry it a couple times starting and stoping each tail session

i am jack's amusing sig file
Named pipes are still pipes and not regular files. For example trying to seek to a particular offset in a named pipe will fail. For that reason, sometimes you can get away with named pipes, and sometimes you can't.
Last time I checked (haven't got time now), named pipes aren't honoured in the GUI. A couple of years back I had a named pipe that had a perl script on the end waiting for someone to read it. No GUI apps could open it. :-(
I went to the trouble of sending Apple feedback about it. Anyone know if this has changed?
UNIX uses named pipes to implement sockets, so sometimes named pipes will show up as FTP servers in the Finder. Other times, I've seen them show up as ordinary files that would completely freeze the Finder if you looked at them funny. For example, by right-clicking on a named pipe, and going to the 'Open With' submenu.
For whatever reason, the shorten command line program doesn't accept '-' as a valid output file (stdout). This prevents you from piping its output into LAME, and getting a direct conversion from SHN to MP3. To get around the problem, I've been using named pipes. Here's my shn2mp3 script: It's worked fine for me, but if anyone out there knows a better, cleaner, safer way to do this, I'd love to hear it.
Nice hint - could be really useful, but I can't seem to get shorten to work. Here's the response in my Terminal: I installed shorten using 'fink install shorten'. Where did you get your from? Any idea what magic number might be about? Despite the error response, 'shorten -h' doesn't give any info about magic numbers.
Oh, not surprisingly, the resulting MP3 file is a wash of static. :-(
My mistake! I used the commands above for SHD->MP3 conversion, when I meant to use the RM->MP3 conversion. Shorten was complaining because I wasn't feeding it an SHD file! Now, if I can just compile mplayer with the realaudio codecs, I'll have this working....
I've spent way too much time in the last 2 days trying to get mplayer to compile for Mac OS X, encouraged by the original example in this thread of being able to convert RealAudio to MP3. (Actually, the version available in Fink compiles fine, but does not support Real codecs. The latest source files fail out of the box with a compilation error since they tries to use a '-rdynamic' option with GCC. Removing that option by hacking the config files gets past compiling, but just causes mplayer to crash later when trying to load Real files.)
I sent a private email to the original hint author (fracai), and he admitted that he based his hint on something he does in Linux.
So, the named pipes is a legitimate concept, but the mplayer conversion of RealAudio files is a bit of a 'tease'. If anyone else can get mplayer to properly read Real files, I'd love to know!
I am trying to convert a non DRM WMA file to mp3 using this method.
i follow theinstructions, substituting where appropriate, and here is what (doesn't) happen.
i make the named pipe
fine no problem
i start lame, so far no problems
i have to go to another terminal window to start mplayer.
as soon as i start mplayer, the mplayer window says broken pipe immediately after outputting 'Starting Playback'
the other terminal window (the one lame was started in)
outputs a bunch of info, and then
Writing LAME tag ... Done.
and quits
Where does the fault lie?
i have never used lame before
and i don't normally use mplayer from the command line
Any ideas?
To make your example work, I had to use `cat pipe` in the second terminal instead of `tail -f pipe`
