Cygwin没有为远程ssh连接注册所有的环境变量[转载, 怕自己忘记了]

Cygwin Doesn't Register All Environment Variables When Using SSH

Submitted by ross on Sat, 01/07/2006 - 13:45

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.

So I added the following code to the end of my .bashrc file:

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

To apply this fix for all users, add it to /etc/profile instead.

Please note, this doesn't correctly register environment variable names that are illegal in Cygwin, such as those that contain a period.
