These scripts help me push files over SSH to another system which has only a simple sh, “cat”, and “ls”. They can continue transferring a partially transferred file (by appending to what was left after an interrupted transfer).

In my case, the other system is a non-rooted Android 2.2 with DroidSSHd installed (with no “scp”, “sftp”, or “rsync”).

The same scripts are useful as a substitute for a local "cp" command if you wish to show the progress of copying or complete a partial (interrupted) copy. (But of course, "cp" ismuch more clever about the features of the FS than "cat" and my "rpush"!)

They are not limited to using necessarily “ssh” (it’s a parameter). For example, for testing them on the same host (or for showing the progress of copying), I use just “eval” instead.

“rpush”

is the basic command to transfer a file by creating a new file on the remote side with the use of only “cat”.

“rpush-continue”

is the command to continue the transfer of a file which is already partially present on the remote (with the use of only “cat” and “ls”).

“rpush-into”

is a wrapper around the two basic scripts which puts the file as a file with the same name in a specified directory on the remote side (like one of the ways to invoke “cp”).
