Can anyone suggest a regular expression to extract the 8 digit numbers that can be submitted in a file that can have the following formats:
file format 1:
1,10000021
2,10000023
2,10000035
3,10000043
file format 2:
10000023
10000035
10000043
10000045
10000060
file format 3:
10000043,,zrous
10000045,,sjandw
10000060,,jnbro2
10000063,,eedwa
10000067,,empav
file format 4:
10000021/1
10000023/1
10000035/1
10000043/1
10000045/1
10000060/1
file format 5:
10000021/1,10000021
10000023/1,10000023
10000035/1,10000035
file format 6:
10000112,10002524,10000998,10000071,10000043,10000612,10000018,10000110,10000011,10000013
I'm currently using this code to iterate over each line in the file:
open(SDATA,">$file")||die "Could not open data file";
@filedata=<SDATA>;
close(SDATA);

foreach $line (@filedata){
        chomp($line);
        #@sid=split m!/\d{8}/!,$line;
        #@sid=split m!,!,$line;
        foreach $nline (@sid){
                  do something ....
                  }
}

TIA.
