How are you outputting the numbers? Are you writing to a file, using print, using printf, etc.? -- Andrew Gaffney System Administrator Skyline Aeronautics, LLC. 776 North Bell Avenue Chesterfield, MO 63005 636-357-1548

See if this one-liner gets you going:
perl -le 'foreach (@ARGV) { s/^0+([0-9])/$1/; print; }' 000015 000000
15
0

Just use the "numbers" in a numeric context:
$ perl -le'
for ( "000000", "000015" ) {
print "String: ", $_;
print "Number: ", $_ + 0;
}
'
String: 000000
Number: 0
String: 000015
Number: 15
