Home -> Community -> Mailing Lists -> Oracle-L -> RE: Unix scripting need help
The few, the proud, the brave.
>From what I've seen of newer admins, developers and dba's in the last few
years, most barely know any scripting, unix or nt.....sad state of affairs
isn't it.
So when ya do run into someone that knows a shell or perl well, give them a hug and always say nice things to them.

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";
}
