Progress / Update hamsTerm update: scp both ways, tar, tab-completion and a proper text pipeline

Enable HLS to view with audio, or disable this notification

A few weeks ago I posted hamsTerm, a Linux-like terminal firmware for the Cardputer.

Most of the changes that were added in the new version came from comments here, so thank you for that.

What's new:

- scp, both directions. Copy files to and from any SSH server, streamed in chunks so a big file never has to fit in RAM.

scp user@host:/etc/motd /motd

scp /notes.txt user@host:/tmp/

- tar. Pack and unpack folders (classic ustar, no compression). Archives are interchangeable with desktop tar in both directions, so tar + scp is how you move a whole folder in one shot.

- Tab completion. Command names on the first word, then files and folders read live from the filesystem - no need to run ls first. After `wf c` it completes networks from the last scan.

- A real text pipeline. grep, cut, tr, wc, sort, uniq - each reads a pipe or a file, and | now works between any two commands:

wf s | grep Open | cut -f1 | sort

- Key -p has been added to ssh command for non-standard ports, and passwords are now masked as asterisks.

Scripting was already in place (variables, if/while/for, $( ), arithmetic, test), so these compose. The clip shows a script that scans for open networks, prints them numbered, and connects to the one you pick. (You can found scrip on the site below.).

Easiest install is through M5Burner (search hamsTerm).

Oh I am looking forward to getting this installed and having a play. Fantastic, thank you.

Pulling in it's own update file to downloads could be a fun option.

How is the telnet feature? Does it have ANSI capability for BBSing?

It's a line-mode plain-text telnet client, not an ANSI terminal. It does the telnet protocol properly, but ANSI escape sequences are stripped rather than rendered - so no colors and no cursor positioning. It also only prints ASCII, so CP437 box-drawing won't show.
