Terminal based assisted management of your SSH config files.
Built out of boredom with managing messy and huge ssh_config files.
Backup your SSH config files before using!
SSHClick can be used with "show" and "list" commands for hosts, without modifying your SSH Config in any way!
Only commands that modify configuration will edit and rewrite/restructure your SSH Config file. In that case, any added comment or infos that are not in form that SSHClick understand will be discarded, and configuration will be re-formatted to match SSHClick style. See below details to understand how SSH Click would keep your config organized!
NEW! Now comes with additional TUI that can be accessed via ssht
command.
- I need something that works fast and great in terminal, and does not require complex setup.
- SSH config is the only config I need to backup.
- SSH config is very feature-full with all options SSH client support, why inventing extra layer?
- I need quick way to search, group and visualize all hosts inside SSH configuration (especially since it can grow huge)
SSHClick (sshc) is just a tool designed to work with existing SSH configuration files on your Linux/Windows/WSL terminal environment.
It parses your SSH config, and can provide easy commands to list, filter, modify or view specific Host entries.
Trough additional "metadata" comments it can add abstractions such as "groups" and various information that is both readable in the configuration file, and can be parsed and printed while using the tool.
-
Check preconditions:
- Currently only tested on Linux (Debian 10,11, Ubuntu 20.04,22.04), but should work on other systems as well
- Minimum python3.7 (tested up to 3.11 beta) & pip installed
- it is preferable to not use system python version, to install "custom" user python on linux, you can try using pyenv (https://github.com/pyenv/pyenv
- git installed (for installing from source)
-
Install package:
-
from PyPI using pip
pip install sshclick
-
(OR) from source using pip
git clone https://github.com/karlot/sshclick cd sshclick pip install .
-
-
Use it as you like,
sshc
command should be available to access SSHClick application, see below chapter for basic usage -
Install shell autocompletion (TAB-TAB auto-completes on commands, options, groups and hosts)
-
Bash - Add this line to end of your
~/.profile
file:eval "$(_SSHC_COMPLETE=bash_source sshc)"
-
Zsh - Add this line to end of your
~/.zshrc
file:eval "$(_SSHC_COMPLETE=zsh_source sshc)"
-
-
Upgrade from new PyPI release:
pip install --upgrade sshclick
-
Upgrade from source: Assuming installation is already done, and previous version is cloned in some local folder
cd sshclick git pull pip install --upgrade .
Simply run:
pip uninstall sshclick
In case you have installed from cloned source code, you can delete locally cloned repo.
rm -r sshclick
SSHClick when editing and writing to SSH config file must use specific style, and is internally using comments to "organize" configuration itself. This means comments outside of what sshclick is handling are unsupported and will be lost when SSHClick modifies a file.)
SSHClick uses comments to add extra information which it can use to add concept of grouping and extra information to hosts. Special metadata lines start with #@<tag>:
or # <tag>:
followed by some of meta-tags like group
, desc
, info
. This are all considered group meta-tags, as they apply on the group level. Note that line separations above and below group header are added only for visual aid, they are ignored at parsing, but are included when modifying/generating SSH config file.
This metadata headers can be added manually also in SSH config, or sshclick can add them and move hosts under specific group, using sshc
cli tool
Normally start of the "GROUP HEADER" inside SSH Config would look like below.
#@group:
or# group:
is KEY metadata tag, that during "parsing" defines that all hosts configured below this "tag" belong to this group#@desc:
or# desc:
is optional tag that adds "description" to defined group, and will display in usual group display commands#@info:
or# info:
is optional tag that can appear multiple times, adding extra information lines tied to the group.
Additionally each "host" definition can have optional meta info:
#@host:
or# host:
is optional tag that can appear multiple times, that can hold some information about the host, this meta info when defined applies to next "host" definition that will appear. If this key is added after "host" config keyword, it will be applied to next host, for that reason, keep this host meta info above the actual host definition.
Following is sample how group header is rendered by SSHClick:
#-------------------------------------------------------------------------------
#@group: <GROUP-NAME> [MANDATORY] <-- This line starts new group
#@desc: <GROUP-DESCRIPTION> [OPTIONAL, SINGLE]
#@info: <GROUP-INFO-LINES> [OPTIONAL,MULTIPLE]
#-------------------------------------------------------------------------------
Host ... <-- this hosts definitions are part of the defined group
param1 value1
param2 value2
#@host: <HOST-INFO-LINES> [OPTIONAL,MULTIPLE] <-- Adds info to following host
Host ...
<ANOTHER GROUP HEADER>
If there are no groups defined, then all hosts are considered to be part of "default" group. SSHClick can be used to move hosts between groups and handle keeping SSH config "tidy" and with consistent format.
SSHClick is deploying sshc
cli tool that allows interacting with your SSH Config file and perform various organization,listing, displaying and modification of SSH Group/Host configuration parameters.
sshc
comes with pre-built lots of help options so each level of commands provide --help
options to provide you info what commands and options are available at which command level.
For example to check version, type: sshc --version
Sample output:
$ sshc --version
SSHClick (sshc) - Version: 0.6.0
If you run sshc
command alone, or adding -h
or --help
option, it will show help what else must be added to the command...
Example:
$ sshc --help
Usage: sshc [OPTIONS] COMMAND [ARGS]...
SSHClick - SSH Config manager. version 0.6.0
NOTE: As this will change your SSH config files, make backups before using
this software, as you might accidentally lose some configuration.
Options:
--sshconfig TEXT Config file (default: ~/.ssh/config)
--stdout Send changed SSH config to STDOUT instead to original
file, can be enabled with setting ENV variable (export
SSHC_STDOUT=1)
--version Show the version and exit.
-h, --help Show this message and exit.
Commands:
config Modify SSHClick configuration trough SSH Config
group Command group for managing groups
groups Lists all groups
host Command group for managing hosts
hosts List configured hosts
tui TUI Interface (experimental)
To manage "groups" type sshc group --help
to see options.
Example:
$ sshc group --help
Usage: sshc group [OPTIONS] COMMAND [ARGS]...
Command group for managing groups
Options:
-h, --help Show this message and exit.
Commands:
create Create new group
delete Delete group
list Lists all groups
rename Rename existing group
set Change group parameters
show Shows group details
To manage "groups" type sshc host --help
to see options.
Example:
$ sshc host --help
Usage: sshc host [OPTIONS] COMMAND [ARGS]...
Command group for managing hosts
Options:
-h, --help Show this message and exit.
Commands:
create Create new host
delete Delete host(s)
install Install SSH key to hosts (experimental)
list List configured hosts
rename Rename existing host
set Set/Change host configuration
show Show current host configuration
test Test SSH host connection (experimental)
SSHClick does not to have its own configuration files, so most of configuration that it tries to understand, come from commands arguments/options, environment variables, and SSH Config file itself.
Sometimes when you want to persist some config options, not to repeat it via command, you can use ENV variables, that can be set trough user shell profile.
Now there is also option to store such config in SSH Config file itself (as metadata comment), so it can be portable and backed up together with SSH Config file.
Command config
takes set
or del
commands that add or remove specific configuration.
$ sshc config --help
Usage: sshc config [OPTIONS] COMMAND [ARGS]...
Modify SSHClick configuration trough SSH Config
Options:
-h, --help Show this message and exit.
Commands:
del Delete config option
set Set config option
$ sshc config set --help
Usage: sshc config set [OPTIONS]
Set config option
Options:
--host-style TEXT Set how to display hosts in 'show' command.
Available:(panels,card,simple,table,table2,json)
(default: panels)
-h, --help Show this message and exit.
$ sshc config set --host-style card
This will now store config in "currently used" SSH config file as following:
#<<<<< SSH Config file managed by sshclick >>>>>
#@config: host-style=card
To delete this config, either remove the line from file manually, or use sshc
command:
sshc config del --host-style
sshc host show
can display host output is several formats, you can specify it with sshc host show <host> --style <style>
Available styles are:
Style | Description |
---|---|
panels (default) |
Display data in several panels |
card |
Add data to single "card" |
simple |
Simple output with minimal decorations |
table |
Flat table with 3 columns |
table2 |
Nested table with separated host SSH params |
json |
JSON output, useful for binding with other tools |
If you want to have some style statically set for your shell, you can export ENV variable with export SSHC_HOST_STYLE=table
, and add it to .profile
or .bashrc
or .zshrc
, so its set when shell session is starting, to set "default" style to that one.
Alternatively, you can use SSHClick internal "config" mechanism to store some config data into your SSH Config file (as commented metadata) so it can be backed up with your SSH config. To do so, you can use following command as example: sshc config set --host-style table
.
In case user do not line "fancy" colors in output, you can set ENV variable to disable all color outputs with export NO_COLOR=1
. If you want it permanently you can add it to startup "rc" files as well.
NOTE! When sending output into non-terminal such as to file, SSHClick will recognize that and will remove all ANSI Escape characters (colors and stuff...) so that output is captured in clear way.
Following demos will use this config sample file as input (located in ~/.ssh/config):
