Need Help on Download Script

[despdan]

Is this poss? i want to download a file & replace part of a line with a line from the file downloaded?

eg: replace 1234567890abcdef in the file with the line 1234567890abcdef & load of writing.

with abcdef0987654321 so the line reads:

abcdef0987654321 & a load of writing.

what i have is:

Sed is great program for doing things like that. Something like this might work :

You don't have permission to view the code content. Log in or register now.

what i can't figure out is getting the abcdef0987654321 out of the downloaded file into the file, if you know what i mean

I think I understand more now...here's another code snippet

You don't have permission to view the code content. Log in or register now.

The "*$" is important. It selects everything from abcdef0987654321 to the end of the line

Ok that takes abcdef0987654321 from the downloaded file & sets it as "line" variable.
What if you don't know the contents of the downloaded file but you know you need the contents & where to put them?

You don't have permission to view the code content. Log in or register now.

Ok my understanding of this line is s=substitute abcdef0987654321 in the oldfile with variable "line" in file called oldfile, am i correct?

You're being waaay too vague

It would substitute the line containing abcdef0987654321 with the variable "line"

OK this is what i'm attempting to do:

Plugin for dreambox thru yellow button that will download a file with the latest ip address.

So say in dreambox the cline is

You don't have permission to view the code content. Log in or register now.

That now has to be changed to

You don't have permission to view the code content. Log in or register now.

So all that would be in the downloaded file would be

You don't have permission to view the code content. Log in or register now.

but the other dreambox would never know the contents of that file & the download file wouldn't know the full contents of the target file.

I know there is dyndns but i want to do it myself & learn a bit as I gounce::thankz:
