Does anyone actually use touch for its intended purpose? Must be up there with cat.

what is cat's use if not seeing whats inside a file?

It is to use along with split. e.g.

You take a single large file, say 16GB
Use split to break it into multiple files of 4GB
Now you can transfer it to a FAT32 Removable Flash Drive and transfer it to whatever other computer that doesn't have Ethernet.
Here, you can use cat to combine all files into the original file. (preferably accompanied by a checksum)

Doesnt computers do this automatically if you try to copy over a file larger than its per file size limit?

No. It just gives an error that it's too big.
