IRIX help -- pipe buffersize

[bigalt]

I'm trying to do,

tail -c-524288 file1 | cat > file2

but file2 comes out to approximately half the size I want.
I _think_ it's because of the buffer size for pipe. Is there a better way to do this, or do I have to go into the kernel and change the buffersize somewhere?

nevermind, used the 'split' command instead

Buffer size shouldn't affect the output, it would just effect speed, theoretically.

oh oops, i just took a look at the man file for tail:

NOTES
Tails relative to the end of the file are stored in a buffer, and thus
are limited in length. Various kinds of anomalous behavior may happen
with character special files. The tail command will only tail the last
256 Kbytes of a file regardless of its line count.
