Extract Uniq prefix from a start and end prefix

Shell Programming and Scripting

Dear All,

assume i have a file with content:

<Start>6000</Start>
<Stop>7599</Stop>

the output is:

6000
7000
7100
7200
7300
7400
7599

how should we use any awk , sed , perl can do this task, means to extract the uniq prefixes from the start and stop prefix.

Thanks
Jimmy

Hi Aia,

Thanks, after run your cmd, the output will be

6000
7599

but the output should be

6000
7000
7100
7200
7300
7400
7599

:confused:

Please explain the logic by which that output is supposed to be produced. I don't see any pattern in taking a starting number and sometimes adding 1000 to it, sometimes adding 100 to it, and sometimes adding 199 to it to reach a stopping number???
