Hello all,<br>
<br>
I am not able to do file test operations in android<br>
<br>
if I am executing below command<br>
<br>
<font size="1">-b /dev/ttyACM0</font><br>
<br>
it is saying<br>
<br>
<b><font size="1">-b: not found</font></b><br>
<br>
if I am executing in script<br>
<br>
<font size="1">device0=&quot;/dev/ttyACM0&quot;    # /   (root directory)<br>
if [ -b &quot;$device0&quot; ]</font><br>
<br>
it is giving <br>
<br>
<b><font size="1">:] not found<br>
  </font></b><font><br>
I tried test -b /dev/ttyACM0 that is also giving error test not found<br>
  <br>
