Hi all,
I'm having trouble with environment variables when running commands through ssh.
I have applied this fix to my /etc/profile:
# When initiating a Cygwin bash session via SSH, Cygwin only registers
the environment variables
# for the SYSTEM account, not for the individual user's account.
if [ "$SSH_TTY" ]; then
pushd . >/dev/null
for __dir in \
/proc/registry/HKEY_LOCAL_MACHINE/SYSTEM/CurrentControlSet/Control/Session\
Manager/Environment \
/proc/registry/HKEY_CURRENT_USER/Environment
do
cd "$__dir"
for __var in *
do
__var=`echo $__var | tr '[a-z]' '[A-Z]'`
test -z "${!__var}" && export $__var="`cat $__var`" >/dev/null 2>&1
done
done
unset __dir
unset __var
popd >/dev/null
fi
This works for standard ssh sessions, but not for commands run through ssh.
The commands I'm running need access to the full environment variable
list, which differs from machine to machine. Here's a summary of
success and failure:
1. 'ssh [EMAIL PROTECTED]' - environment variables okay with a normal ssh
session.
2. 'ssh [EMAIL PROTECTED] bash --login -i' - only some environment variables.
3. 'ssh [EMAIL PROTECTED] mycmd - doesn't work due to missing environment
variables.
To illustrate, consider the difference between 1 and 3, here's the
environment variables section of the output to cygcheck -sv:

This is a new problem since upgrading Cygwin. Is there a bug that
needs to be fixed, or is this the correct way for Cygwin to function
and I need to do something new to make it work?
I tried the fix above as a separate script (with out the SSH_TTY
requirement of course), but that didn't help either.
Any help would be greatly appreciated.
Regards,
Paul
