Blimey! Doesn't anyone know korn shell out there any more. Perl perl perl -- that's all I ever hear anymore. It gets old... (I'm gonna have to buy Jared's book one of these days).
x=${file1%.log}
file_tag1=${x#mylogfile}

If you take RAC out of Oracle you get OLE! What can this mean?

Is your purpose to simply display the numbers or to generate the maximum in order to start naming new files?
If the latter seriously consider using a timestamp:
i=$(date +%Y%m%d%H%M%S);
this solves all of the math for you automaticlly. A onesecond sleep at the start of your program guarantees that you will not re-use the names.
To get the digit strings out you could use sed or perl:
i=$( echo $file | sed -e 's/[^0-9]*//g' )
or use perl for the code instead of shell:
for( @ARGV )
{
my ($i ) = /(\d+)/;
Print "File and number: $_, $i\n";
}
