Hello,
I'm trying to tail a file through SSH. I'm launching ssh through
Python, like this:
ssh -t user@vm-admin.corp.com "tail
/cygdrive/c/ctier/ctl/var/logs/ctlcenter/STAGING/Administration/\[Staging\]\
Sleep/7.txt"
And I get this:
Pseudo-terminal will not be allocated because stdin is not a terminal.
TAIL: lseeki64() failed 22
This works from the command line :(
Also head fails with:
Pseudo-terminal will not be allocated because stdin is not a terminal.
bash: /cygdrive/c/apps/activeperl/bin/head: /usr/bin/perl: bad
interpreter: Permission denied
This also works from the command line :(
The Cygwin version is: CYGWIN_NT-6.0-WOW64 1.7.9(0.237/5/3) 2011-03-29 10:10
Any ideas?
Thanks,
_____________

This is not Cygwin's tail. The error message looks pretty weird.
Try ssh -tt.

You're running the wrong head command. This is some activestate perl
script, not the Cygwin head tool from coreutils. Change your $PATH
to find the Cygwin apps first.
