Hi,
I’ve noticed that the following is broken in Cygwin 2.2.0-1. It works in Cygwin 2.1.0-1.
yes | head -10
This fails to exit on Cygwin 2.2.0-1. It correctly exists on Cygwin 2.1.0-1.
Cheers,
Mark.

Does *not* work for me in an 'xterm' launched from the X toolbar icon.
I see the same error.
I don't see this with other commands, though. 'ls -l | head -10'
works just fine.
Okay, now this is really weird.... I have a hotkey set up in
AutoHotKey (Alt-Shift-T) to launch a new xterm. It calls HSTART
(http://www.ntwind.com/software/hstart.html) with /NOCONSOLE /SHELL
which then runs a '.bat' file that runs:
c:\cygwin64\bin\bash.exe -i -c "exec /usr/bin/xterm -ls -u8 -display
:0.0 >/dev/null 2>&1 &"
Any 'xterms' I open with this *work just fine*. Any I open from the
X11 taskbar *do not*. From my system.XWinrc:
menu apps {
xterm exec "xterm -ls -u8"
...
}
Usually, I use my hotkey to open windows, so I haven't noticed if/when
I get this IO error for similar commands.
I opened multiple xterms via both methods and confirmed that my hotkey
version always works and the menubar version never does.

it seems a race issue, on xterm I have
$ yes |head -n 20
y
...
y
yes: standard output: Broken pipe
yes: write error
