[gentoo-user] lftp -u user,pass(word

[hw]

Hi,

how do you use lftp (to mirror a remote site)
when the password you have contains a bracket?

I'm trying 'lftp -u user,pass(word ftp.example.com', and
there appears to be no way to escape characters in the
password.  Using single quotes also doesn't work, same
as 'lftp 'ftp://user:pass(word@example.com'.

It works with an entry in ~/.netrc, though I don't
exactly want to have to use that.

Try lftp 'ftp://user:pass\(word@example.com'
or  lftp ftp://user:pass\\\(word@example.com

The \ escapes the ( and the single quotes protect it fro the shell. In
the second way, you escape the \ as well.

That's what I thought :)  I already tried and it didn't
work.

Did you try putting single/double quotes around passwd only?

Have you tried:
lftp -u "user,pass(word" ftp.example.com
?

Maybe that works.

Yes, that didn't work, either.

I had a quick look at the man page and it says that parentheses can be
used to group commands, so maybe lftp is misinterpreting the ( in this
way.

However, the man page also advises against giving the password on the
command line (because it is then available to anyone with normal user
shell access while the command is running) and suggests using either
~/.netrc, which you have already said works, or $LFTP_PASSWORD along
with --env-password. Have you tried this?

LFTP_PASSWORD='pass(word' lftp --env-password -u user ftp://example.com

I need to use it with a script for automatic downloads, so the password
wouldn't appear in the history.  Using a ~/.netrc would create a
dependency on the user who runs the script, which is something I would
prefer to avoid.

Thanks, that looks like a good solution.  I'll see if that works ...

It's not just the history, the password appears in the putput from ps
while the transfer is running.

If that doesn't work, you could always sidestep the issue by changing the
password to "password1" ;-)

I remember banging my head against a brick wall trying similar methods to get 
ssmtp to use a passwd with special characters.  It would only accept 
alphanumeric characters.  I wasn't sure if this was a bash or an ssmtp 
problem.  I ended up changing the passwd.  :-(
