Description of the issue

I have many connections configured in .ssh/config When I use cmd::Cmder type of terminal autocompletions works, I print ssh, press Tab and see all names of connections. But if I use bash::bash type of terminal, Tab shows folders in current folder:

λ ssh
bin/                config/             LICENSE             vendor/
Cmder.exe           icons/              opt/                Version 1.3.24.236

Cmder comes with a small collection of completion scripts for the cmd shell. Cmder does not come with completion scripts for bash.

The scop/bash-completion repo contains a large collection of completion scripts for bash. Directions for installing it are here.

@anutator I am sorry I thought I responded to this yesterday but I guess I never hit the Comment button.

While the instructions @chrisant996 pointed at may work for Cmder, I would recommend another approach for install in Cmder if you want to:

Not have reconfigure this EVERY time you update Cmder to a new version. (Depending on how you do it.)
Maintain the portability of Cmder.

Add any bash auto completion files to a folder called $cmder_root/config/bash-completion that you create.
Create a file $cmder_root/config/profile.d/bash-completion.sh and source the files you want to use in this file.
```
. $cmder_root/config/bash-completion/ssh
. $cmder_root/config/bash-completion/scp
```

or adapt those instructions using the info here. I just do not recommend putting the files inside the $cmder_root/vendor/git-for-windows folder.

@anutator to specifically answer your question this is what I did:

296951@DESKTOP-V3893H0 ~
λ cd $cmder_root/

296951@DESKTOP-V3893H0 ~/cmderdev (more_speed_2)
λ cat config/profile.d/bash-completion.sh
. $cmder_root/config/bash-completion/scp
. $cmder_root/config/bash-completion/ssh

296951@DESKTOP-V3893H0 ~/cmderdev (more_speed_2)
λ cat config/bash-completion/*
_scp()
{
  local cur prev opts
    COMPREPLY=()
    cur="${COMP_WORDS[COMP_CWORD]}"
    prev="${COMP_WORDS[COMP_CWORD-1]}"
    opts=$(grep '^Host' ~/.ssh/config ~/.ssh/config.d/* 2>/dev/null | grep -v '[?*]' | cut -d ' ' -f 2-)

    COMPREPLY=( $(compgen -W "$opts" -- ${cur}): )
    return 0
}
complete -F _scp -o nospace scp

_ssh()
{
        local cur prev opts
        COMPREPLY=()
        cur="${COMP_WORDS[COMP_CWORD]}"
        prev="${COMP_WORDS[COMP_CWORD-1]}"
        opts=$(grep '^Host' ~/.ssh/config ~/.ssh/config.d/* 2>/dev/null | grep -v '[?*]' | cut -d ' ' -f 2-)

        COMPREPLY=( $(compgen -W "$opts" -- ${cur}) )
        return 0
}
complete -F _ssh ssh
