split file with according to size

[Babu]

Hi,

I have a input file called temp.hex (163840 bytes) . Is there any
function in perl that does the file splitting with size of the file
information

tempA.hex(81920 bytes) and tempB.hex(81920 bytes)
or

tempA.hex(3840 bytes) and tempB.hex(16000bytes)

Thanks in advance

There's a Unix utility which does this. The name of the utility is,
oddly enough, split.

split -b 81920 <file>

No, Perl does not have a function with this functionality. It is a rather
special request and it would be odd, if Perl as a general purpose language
would provide a separate function for each and every uncommon file handling
request.
But is trivial to write your own. Just open() the source and target files,
read() as many bytes as you want to go into the first target file, print()
those bytes to the first target file, and then repeat read()ing and
print()ing for the second target file.

However I would just use the external split program instead. Why reinvent
the wheel after all?
