(tye)Re5: Slurp a file

Unfortunately, this isn't completely portable. There are minor (as far as I can tell) problems with some operating systems where the size of a file on disk doesn't always match the size of data read into memory.

The big problems have to do with the great many types of filehandles where -s can't tell the file size.

But, yes, when it works, this is a neat trick. Thanks.

Just a few questions: What types of filehandlers would not return the correct size with -s? And do you know a better way to get the size of a filehandle than using -s?	[reply]

What types of filehandlers would not return the correct size with -s? Mostly pipes and user input devices (terminals/consoles). `-s` pretty much only works on file handles connected to oridinary files. For the other cases, the only way to determine the amount of data before EOF is to read it all. - tye (but my friends call me "Tye")	[reply] [d/l]
