I have a weird situation here... two out of three of my servers refuse to give any output to the command ls -1tr | tail -1

There are definitely files in the directory but it gives no output what so ever (returns nothing and goes back to the prompt)... simply typing ls or ls -c works but not ls -1tr | tail -1

x2 Server 2003

x1 Server 2008

Only one of the Server 2003 gives the correct response to the command.

I have put the /bin directory in the windows environmental path field so I don't think that is the problem.

Any suggestions?

Does the more formal ls -1tr | tail -n 1 work? –  p.vitzliputzli Mar 13 '11 at 18:03

The tail -[number] syntax is no longer valid by POSIX.1-2008. Maybe you are using different versions of the coreutils and that is why you are experiencing different results. The correct syntax is ls -1tr | tail -n 1.

Corrected it! Thank you! –  p.vitzliputzli Mar 13 '11 at 20:05

Besides from trying to upgrade your cygwin installations, you could try to use ls -1tr | tail --lines=1. –  p.vitzliputzli Mar 13 '11 at 20:54

Errno 22 is probably EINVAL, i.e. invalid argument. It sounds like you have encountered a cygwin bug. Nevertheless, could you please post the coreutils/tail-version? tail --version –  p.vitzliputzli Mar 14 '11 at 11:46

Yes, I would try that with the default installation. –  p.vitzliputzli Mar 14 '11 at 14:00

Maybe you have to change the PATH-var in Windows to your new cygwin installation. –  p.vitzliputzli Mar 14 '11 at 15:34
