export variable

[Bauder, Alexander]

Hi2all,

I have some bad problem with a script who should check all my users whose password is the same as the login - name. I tried it with an ftp - server.

Here it is:
for USER in `/usr/bin/ypcat passwd | awk
-F: '{print $1}' `
do

{
ftp -n << !
open SERVER
user $USER $USER

!
}
done

The problem is, variable $USER isn´t seen in
the ftp - call.

thank

Use export USER and see if that works or
after
for USER in `/usr/bin/ypcat passwd | awk
-F: '{print $1}' `
do
export user=$USER
and then use $user in ftp script

It is also possible to create a .netrc file with the script and then call the "ftp " in your script. Check the return codes for the result if the username=password.

This came up before.

Inside a here document (ie the bit between the "<<" and the "!", some characters, including $, need escaping.

Try changing "$USER" to "\$USER" both times.

My previous post was wrong.

Here's the earlier thread, doesn't look like it was resolved though....

Hello folks,

thank you very much for your reply!

I´d tried the export - dialog before I called the forum, but there it doesn´t work, and now it does?!?

How can I get the Returncode ( $? )??

Thanks

Hi,
if you run your script like this:
# sh -x
what error messages do you get?
Btw: does the first line: from "for USER" until and including the second backqoute appear on a single line?

Hi,
first: dont use the variable name USER - it is used internally on some systems.

second: Send the ftp-command via a pipe

(KSH-like):
for usr in $(ypcat passwd | awk -F: '{print $1}')
do
ftpout=$(print "open SERVER\nuser $usr $usr" | ftp -n 2>&1)
[ -z "$ftpout" ] && print $usr
done
