I have a problem:
On the MUD i play there are information.. Like when people die and such..
it looks like this: [INFO] Player was killed by mob. and so on..
Now I write it in to a file called info.txt and so far everything's cake.. But here comes the problem..
I want to be able to read the last 20 shows in that file..
But the %read or the #read commands doesnt support reading from the bottom of a document.. That means I have to fix it with the #write command instead.. So is there some way of writing at the start of a document instead of the bottom?

I would be really glad if someone could help me with this problem..

You're right, you can't directly tell the %read function to read the last 20 lines, but by using other functions, it can be done. Example:
#LOOP (%filesize(1)-20),(%filesize(1)) {#SH %read(1, %i)}

Can you explain what the command does Kjata?

I realize it's looping, but how is it counting record numbers? or is it? I was just trying to figure a way for an alias to count the number of lines, then subtract then send the #READ command with the previous numbers.

Killing a fly on a friends forhead may not be overkill, use a hatchet to make sure the job is done.

Ok, This is what I see, first off, #LOOP takes range as its first argument, SO! %filesize(1), gets the number of lines in the file, which lets say its 100, So, the -20 sets the first range, to 80 (it subtracted 20), then the second range, is... 100, because its getting the TOTAL number of lines. The action that it does is show each line in turn that you started at, until you reached the last line. hrm, Hope that explains it.

Thanx for that.. It works perfectly.. /PathetiC

Yup, what Agroamar said. It has the effect of reading the last 20 lines of a file, no matter how big the file is.

Thanks Agroamar and Kjata.

It must have been too early. I never recongnized the filesize function. The explantion helps alot though. 'Precciate it.
