Expr Quoting

Hi,

Can anyone help?

Heres what i'm trying to achieve.
a=degz.log

return the part of the string "degz"

here's where i'm at.
a=degz.log
b=`expr index $a "." - 1`
c=`expr substr $a 1 $b`

What I would like to do is substitute $b in the last command for the expr index command, however i'm sure i'm getting something incorrect with my quoting ( or lack of it! )

The command I would like would look something like:
a=degz.log
b=`expr substr $a 1 `expr index $a "." - 1``

Can anyone point me in the right direction please.

Regards
Degz.

I think it's too late to answer now,
but anyway.

Try this:

<?php
$a = 'a=degz.log';

preg_match('/=(.*)./Ui', $a, $m);
echo $m[1];

echo '<br />', substr($a, strpos($a, '=') + 1, strpos($a, '.') - 2);
?>
