    <p>I'm trying to write my first expect script which will push new language to a remote file.</p> <p>This is what I have so far that isn't really working:</p> <pre><code>#!/usr/bin/expect set fid1 [open ./hosts.list r] set hosts [read -nonewline $fid1] close $fid1 set banner_cmd "cat &gt; /tmp/new_sshd_banner &lt;&lt; EOF &lt;New Language Goes Here&gt; EOF" send "\n" stty -echo send_user "Enter password for remote sudo: " expect_user -re "(.*)\n" stty echo set pass $expect_out(1,string) send "\n" foreach host [split $hosts "\n"] { eval spawn "/usr/bin/ssh $host" expect { -re "RSA key fingerprint" {send "yes\r"} timeout {puts "Host is known"} } expect "$host" send "sudo mv /etc/file /etc/file.orig" expect "assword" send $pass expect "$host" send "sudo $file_cmd" expect "$host" send "sudo mv /tmp/file /etc/file } </code></pre> <p>When it runs, this is what I see:</p> <pre><code>opensuse @ 15:10 ~/bin&gt; ./fix_file.exp Enter password for remote sudo: spawn /usr/bin/ssh server &lt;New Language Goes Here&gt; Last login: Fri Aug 31 19:52:45 2012 from 10.152.81.105 [user@server ~]$ Host is known sudo cat &gt; /tmp/new_file &lt;&lt; EOF &gt; &gt; &gt; &lt;New Language Goes Here&gt; &gt; &gt; EOFsudo mv /etc/file /etc/filePASSWORD*missing " while executing "send "sudo mv /tmp/file /etc/file " ("foreach" body line 17) invoked from within "foreach host [split $hosts "\n"] { eval spawn "/usr/bin/ssh $host" expect { -re "RSA key fingerprint" {send "yes\r"} timeout {puts "Host i..."

A row detail

Detail views are divided into sections. All the information in the data section comes from columns in the selected row. The other sections display data from other, related rows.

Related data can be related in a to-one or a to-many fashion. Captions of data related in a to-many fashion link to a list view showing a filtered view of the table.

Try moving around until you find a non-empty to-many entry and click on the label to get to one. You can move back to the root by clicking on the database name in the header.
