Problems with net use statement via sshd on cygwin

[Jason B. Alonso]

Hello,

I frequently rely on the per-user nature of the net use command through ssh.
So much so, in fact, that I wrote shell scripts that allow me to encrypt
other shell scripts (namely, those that contain multiple net use commands
with passwords) using gpg into self-extracting+executing (with help of
passphrase) secured shell scripts.  If there is interest, I can post my
script-making scripts.

I should add that I never map the drives, but rather run "net use
\\server\some-share /USER:domain\user password" (backslashes are more
prevalent than they appear) and use symbolic links into //server (yes, I
leave off the share, so I can "cd /net-link/another-share" into whatever
share I want).

Regards,
Jason Alonso

Exactly.  Any time you have another shell parse the input, you have to
escape all the backslashes again (both the escapes and the real things).
This will also require it:

sh -c "net use j: \\\\\\\\server\\\\host /u:${user} ${password}"

Of course, single quotes are the preferred way to deal with backslashes,
but they don't get you variable expansion, e.g., as above.
Hope this helps,
	Igor
