• In /etc/ssh/sshd_conf, set UsePrivilegeSeparation to no
• In /etc/ssh/sshd_conf, temporarily enable plaintext passwords
• In /etc/ssh/sshd_conf, change port (e.g. to 23) to avoid confusion with Windows SSH server
• sudo service ssh restart
• Add alternative port as a new rule to Windows firewall
• On the client: ssh-copy-id user@server
• In /etc/ssh/sshd_conf, re-disable plaintext passwords

To fix Could not load host key ... error:

• sudo ssh-keygen -t rsa -f /etc/ssh/ssh_host_rsa_key

How to automatically start ssh server on boot on Windows Subsystem for Linux

Microsoft partnered with Canonical to create Bash on Ubuntu on Windows, running through a technology called the Windows Subsystem for Linux. Below are instructions on how to set up the ssh server to run automatically at boot.

1. Edit the /etc/ssh/sshd_config file by running the command sudo vi /etc/ssh/sshd_config and do the following
   1. Change Port to 2222 (or any other port above 1000)
   2. Change PasswordAuthentication to yes. This can be changed back to no if ssh keys are setup.
2. Restart the ssh server:
   • sudo service ssh --full-restart
3. With this setup, the ssh server must be turned on every time you run Bash on Ubuntu on Windows, as by default it is off. Use this command to turn it on:

Remove old commits from local repo

Shallow fetch from self:

Keep only last n commits--

git fetch --depth=<n-1> . <branch>

The readline prompt [read -p] is sent to stderr

The prompt for interactive bash is also sent to stderr. See POSIX mandate below

Source : https://pubs.opengroup.org/onlinepubs/9699919799/utilities/V3_chap02.html

PS1 :: Each time an interactive shell is ready to read a command, the value of this 
variable shall be subjected to parameter expansion and written to standard error.

NOTE (source- Bash reference manual):

# This function dumps the input stream to the path given as parameter.
# If PATH gets unlinked by another (cooperative) process, it creates a new file at PATH and continues dump
# Provide a lockfile as the 2nd positional parameter. This is needed so that another process doesn't remove PATH
# when it is being written to.

stream_dump(){
  declare -x path="${1}"
  local lock="${2}"
  local timeout="1" # Interval for polling $path
  declare -x line

# First run the following 2 lines in your interactive bash attached to a controlling terminal
export bashpidfile="/tmp/bashpid" # File that stores the bash pid
export PROMPT_COMMAND='echo $$ > $bashpidfile' # Or, replace $$ with $BASHPID

# From another terminal do the following
### TPGID gives fg proc group on the tty the process is connected to, or -1 if the process is not connected to a tty
fgpg=$(ps --pid $(awk NR==1 $bashpidfile) -o tpgid=)

# Send signal SIG to all foreground processes to emulate user Ctrl- inputs
# Ctrl-C: INT, Ctrl-Z: TSTP, Ctrl-\: QUIT
