Forums: 

<p>All -&nbsp;</p>

<p>Im good at linux but not at expect/send :</p>

<p>below is the function i have written for trying to connect to respective iam role.</p>

<p>&nbsp;</p>

<p><br />
function passingvalues {</p>

<p>expect &lt;&lt; EOF<br />
spawn $AWS_USERNAME -c "exit"<br />
expect "password:"<br />
send "$AWS_PASSWORD\r"<br />
expect "role:"<br />
puts "$expect_out(buffer)"<br />
foreach line [split $expect_out(buffer) "\n"] {&nbsp;&nbsp;<br />
&nbsp; &nbsp; &nbsp;if {[regexp -nocase "arn:aws:iam::54250:role/OM-NonProd_RedshiftServices-DevUsers-Team-Support" $line]} {<br />
&nbsp; &nbsp; &nbsp; &nbsp; &nbsp; puts $line<br />
&nbsp; &nbsp; &nbsp; &nbsp; &nbsp; &nbsp; &nbsp; &nbsp;}<br />
&nbsp; &nbsp; &nbsp; &nbsp; }<br />
expect eof<br />
EOF<br />
&nbsp; &nbsp; &nbsp; &nbsp; &nbsp; &nbsp; &nbsp; &nbsp; &nbsp; &nbsp; &nbsp; &nbsp;}&nbsp;</p>

<p>error : it is unable to iterate through the list of roles displayed and unable to connect.</p>
