Versioon 1.1.0 lisab MS Windowsi toetuse ilma emuleerimiseta.
Võimalus jagada käsurida Pythoni abil reaalajas veebipõhiselt ja võimaldada õppuritel paremini jälgida tunnis antud käske ja nende väljundit ja vältida ümberkirjutamisest tekkivaid vigu. Võimalus ka virtuaalmasinast otse käsurida edastada. Edastamine toimub vaid vaatamisrežiimis. Kui soovitakse muutmisrežiimis (aka collaborative hacking) siis näiteks vabavaraline upterm võib huvi pakkuda.
Paigaldamine
Uusima shellshare'i versiooni kiire paigaldus Linuxis kestprogrammi Bash korral
mkdir -p ~/.local/bin/ && wget -q --show-progress https://raw.githubusercontent.com/vitorbaptista/shellshare/master/public/bin/shellshare -O ~/.local/bin/shellshare && chmod u+x ~/.local/bin/shellshare
echo "alias lühikäsunimi='shellshare --server http://linux.itcollege.ee:3000 --room ruuminimi --password ruumisalasõna'" >> ~/.bash_aliases && source ~/.bash_aliases
Palun asendada lühikäsunimi, ruuminimi, ruumisalasõna soovitud väärtustega.
Kasutatud otsiteekonna (path) toimimiseks Bash'i korral tuleb jälgida, et ~/.bashrc sisaldaks ridu:
# set PATH so it includes user's private bin if it exists if [ -d "$HOME/.local/bin" ] ; then PATH="$HOME/.local/bin:$PATH" fi
~/.bashrc muudatuste jõustamiseks:
source ~/.bashrc
... või siis sulgeda kõik senised terminalide sessioonid ja avada uuesti terminal. Kui on mõni teine kestprogramm kasutusel, siis tuleb jälgida selle seadistuse nõudeid.

Seda aadressi saab aegsasti ka õppuritele jagada, mida tunni ajal siis avada saab.

Võimalus teha ka lühikäsk ehk alias (vt Alias bash shellis, .bash_aliases), skript vms käsurea jagamise kiireks käivitamiseks soovitud ruuminimega
Edastamise lõpetamine
Käsurea edastamise lõpetamine: exit+Enter, sageli toimib ka CTRL+D
Erilised tänud
Erilised tänud TalTechi IT Kolledži Linuxi administraatorile Veiko Tuul serveripoole käivitamise ja selle suurepärase võimaluse loomise eest!

Version 1.1.0 adds MS Windows support without emulation.
There is an option to share command-line over Internet in real time using Python. This allows for students to follow lecturer commands and its output and avoid mistakes of rewriting commands. Streaming is going only in read-only mode. If there is edit mode needed (aka collaborative hacking) then probably free and open-source upterm is one of the choices you may be interested in.
Setup
Quick install for newest version of shellshare in Linux in case of Bash shell
mkdir -p ~/.local/bin/ && wget -q --show-progress https://raw.githubusercontent.com/vitorbaptista/shellshare/master/public/bin/shellshare -O ~/.local/bin/shellshare && chmod u+x ~/.local/bin/shellshare
echo "alias shortname='shellshare --server http://linux.itcollege.ee:3000 --room roomname --password roompassword'" >> ~/.bash_aliases && source ~/.bash_aliases
Please replace shortname, roomname, roompassword with appropriate values, you wish to use.
For ensuring the used path works in case of Bash there must be in ~/.bashrc the following lines:
# set PATH so it includes user's private bin if it exists if [ -d "$HOME/.local/bin" ] ; then PATH="$HOME/.local/bin:$PATH" fi
for applying changes in ~/.bashrc:
source ~/.bashrc
... or close all existing Bash terminal sessions and reopen the terminal. If there is any other shell in use, then its configuration requirements must be followed.
From now on, it is enough to open the terminal and you can quickly use it by entering the specified short command name. When started, the terminal also says the address from which others can then see the commands entered in the terminal, in near real time. This address can also be shared with students in a timely manner, which students can then open during class.
- download the appropriate script at https://github.com/vitorbaptista/shellshare/releases - choose Latest Release
- there is also program homepage where download command is described but it might happen that the site is offline
- from unpacked folder there can be found the script in public/bin/shellshare - this can be renamed to shellshare.py and copy whenever needed. There is also possible to copy unpacked shellshare script to somewhere in the web so you can quickly download e.g. into virtual machine.
Streaming
If Ubuntu does not have a python link pointing to a newest version of python installed, you need to create one. Let's see what's there: type python and press the TAB key at least twice quickly. If python is not included in the list, you need to create it:
sudo ln -s /usr/bin/python3 /usr/bin/python
To start (almost) real-time command line streaming:
- fast connection
shellshare
This will launch a randomly generated hashed address, visible at https://shellshare.net/r/<hash>
- you can also specify a room and password
shellshare --room roomname --password password
Then it will be visible at https://shellshare.net/r/roomname
Streaming via IT College server:
shellshare --server http://linux.itcollege.ee:3000 --room roomname --password password
Then it will be visible at http://linux.itcollege.ee:3000/r/roomname
- replace
- roomname with the name
- password with the password
- commands sent to the web are copyable, history can be viewed by scrolling back (it is not recommended to clean the command line while using shellshare)
- files opened on the command line, man pages, etc. are also displayed; movement, text marking using the keyboard are also displayed in the web stream
Transmitting a command line from multiple terminals to the same address at the same time is also supported - this way it is possible to simultaneously transmit a command line from a class computer, from a virtual machine, etc. to the same session at the same time - this way the information is in one place for the student. The information must be copied, because the history is not preserved when the transmission ends and the window is closed.
Fast usage
There can be an alias created (see also .bash_aliases), script etc to start quickly streaming command-line with appropriate settings.
Stop streaming
To stop command-line streaming: exit+Enter, usually also CTRL+D works.
Special thanks
Special thanks goes to TalTech IT College Linux administrator Veiko Tuul to set up server side and offering such a great opportunity!
