Listed programs:
scp- "potentially deprecated"e/fgrep- replaced withgrepflagsnet-tools, which includesnetstatarprouteiptunnel*nameififconfigiwconfigiptablesReplacement:
scp→rsyncorsftpegrep-->grep -Efgrep-->grep -Fnetstat-->ssarp-->ip nroute-->ip routeiptunnel-->ip tunnelnameif-->ip linkifconfig-->ipiwconfig-->iwiptables-->nftablesrsync is cool but is nowhere a replacement for scp's main use case. scp actually uses your SSH client settings file, whereas rsync doesn't (it does have the opportunity to use a SSH command, which you then have to setup separately).
I'm not sure I get what you mean. In every distro I used so far rsync did use ssh by default so it would honor everything I set in the ssh config.
Not everything however. For it to catch some options , for example SOCKS bridges, you have to use the SSH passthrough notation aka
rsync -e 'ssh bridgename...' --rsync-options.... And ofc if you have to load a different SSH conffile, you have to use the while passthrough for that as well, there's no rsync native option to load a SSH conffile:rsync -e 'ssh -F conffile ssh_options...' --rsync-options....
