<p class="MsoNormal" style="margin-bottom: 12pt;">Hi All,<br>
<br>
I am trying to access the contents of a file in a remote machine and
store the
contents in string.<br>
<br>
The command,<br>
os.execv(ssh, [ssh, "-l", user, ip] + ['cat /tmp/temp.conf']<br>
works but displays the output on to the screen.<br>
<br>
I tried,<br>
to_be_analysed_txt = os.execv(ssh, [ssh, "-l", user, ip] + ['cat
/tmp/temp.conf']<br>
but that does not work out.<br>
<br>
Regards,<br>
<br>
KartheeK</p>
