Minimal File Transfer
The goal of this article is to find an easy and minimal way to
transfer recursive directory changes to a host which does not
have git nor any other high-level tool like rsync.
Transfer should be done by netcat and on the other end the received data should be run by shell (straight from stdin after decompression).
$ diff -arq jasan-val1 jasan-val2
Only in jasan-val2: ahoj.txt
Only in jasan-val2: aoeui
Files jasan-val1/httpd.conf and jasan-val2/httpd.conf differ
Only in jasan-val1/nginx: nginx.sh
Only in jasan-val1: processmail.sh
Only in jasan-val1: processmail.sh-old
Only in jasan-val2/public_html: dir
Only in jasan-val1: var.tar.gz
Half-way through thinking about a solution I found something very similar, just too complicated for what I need:
The result is a script which requires only base64,
tar, diff, patch, rm, and sh, all basic commands on
POSIX systems.
