Replace after nth occurence
 

Hi,

I need some help with following:

I have a file wich contains the following:

123;345;456;335;234;244;245;2345;234;234;345;

There are 11 semicolons in this, I would like to have an output where after the 8th semicolon all semicolons are replaced by space (" ") so the output will be:

123;345;456;335;234;244;245;2345;234 234 345

I tried some sed functions, but could not execute the proper command.

Hope you can help me out.

Thanks.

would be nice to know what did you really try.
Probably you need to check the gnu sed (instead of the non-gnu version) it has some interesting extension.

It's a little complicated in sed but easier in perl. Either way, can you show what you have tried so far so we can see where you need help?

Most easy with a loop
Substitute the 9th semicolon, repeat if successful.
