Unix command?

In Unix, y is a command to join the output of two streams.

Is it, really? I have never heard about that (not that I would be some kind of Unix hacker), that program is not on the List of Unix programs, nor could I find anything using Google (but trying to search "y" is quite difficult). Could you point to anything about the program? --Mormegil 21:16, 29 Sep 2004 (UTC)

I may be wrong. I realized that I know it from the JP Software command shells (4DOS, 4OS2, Take Command and the like). I would be surprised if 4DOS would have better support for piping than Unix shells.

I may have misremembered the function of the program. From help

Purpose: Copy standard input to standard output, and then copy the specified file(s) to standard output.

Format: Y file ...

The Y command copies input from standard input (usually the keyboard) to standard output (usually the screen). Once the input ends, the named files are appended to standard output.

[c:\] y memo1 memo2 > memos

[c:\] dir | y dirend > dirall

Well, in Unix, you can achieve the same thing with cat /dev/stdin file ..., so I don't think there would be a special tool for it. So I think it probably is not a Unix command; I'm going to change the article to refer to 4DOS instead.

Dutch name

"Diphthongs"

In the section discussing Y's pronunciation in English, it says that it sometimes forms a diphthong with E or A, &c. This is talking about writing and letters, so shouldn't this be replaced with 'digraph'? DdeWylvyn (talk) 04:11, 9 August 2024 (UTC)[reply]

Icelandic

As this article is locked: Y is mostly called ypsílon in icelandic and Ý called ypsílon í - ypsílon i is only used when we differentiate between the two. We also write ypsílon sometimes as yfsílon, and even ufsílon or ufsilon. — Preceding unsigned comment added by ~2025-38256-14 (talk) 00:47, 4 December 2025 (UTC)[reply]
