Bashhub – Access Your Terminal History From Anywhere

Bashhub - Access Your Terminal History From Anywhere

As you already know, all commands you run on your shell will be saved and you can view them at any time either by using history command or using UP/Down arrows keys or doing a reverse search using CTRL+R key combination from the Terminal. All commands that you run on the Terminal will be saved in .bash_history file. But you can view, access, and re-run them only from the same machine itself. What if you want to access your Terminal history from a different system on the network? No problem! Here is where “Bashhub” utility comes in help. It is a simple online web service where you can save all commands and access them from anywhere. Bashhub saves every commands entered across all sessions and systems, so you can access them from anywhere. To put this simply, your entire BASH history will be available in the cloud and the entire bash history is indexed, and searchable! Bashhub is completely free and open source.

All commands will be stored in Bashhub’s database which is encrypted using storage level encryption via LUKS. Bashhub will generate a unique identification token to each user. This token is mandatory to perform any actions on behalf of a user for the command api. All commands recorded on behalf of a user are only accessible using that user’s authentication token. There is currently no way to share these commands and they’re not publicly accessible. Also Bashhub allows you to ignore some commands that contains sensitive information like user’s password. You can safely ignore such commands from being recorded by Bashhub to turn off the recording completely at any time.

Installing Bashhub

Make sure you have installed Python 2.7 on your system. Python 2.7 is available in the default repositories of most Linux distributions, so you can install it using your distribution’s package manager. For example, run the following command to install python 2.7 on Debian and variants.

sudo apt-get install python2.7

After installing Python 2.7, run any one of the commands given below depending upon the SHELL you use.

If your shell is BASH, enter the following command:

curl -OL https://bashhub.com/setup && bash setup

For Zsh:

curl -OL https://bashhub.com/setup && zsh setup

After few minutes, you will be asked to create a new account if you don’t have already one. Enter a valid Email id, username and password and your system’s name.

What's your email? sk@senthilkumar.com
What username would you like? sk
What password?

Email: sk@senthilkumar.com Username: sk
Are these correct? [Y/n] y
Registered new user sk

What do you want to call this system? For example Home, File Server, ect. [ubuntuserver]: 
Registered a new system ubuntuserver
Should be good to go! Please close and restart your terminal session.

Done! Your account has been created at Bashhub. You can access your profile at https://bashhub.com/<your-user-name>. Bashub will create a directory named .bashhub that contains a few scripts and a python virtual environment in your $HOME directory.

If you’re an existing user, type “n” when you ‘re asked “Are you a new user?” and enter your registered Email and password.

Close and restart your Terminal to start recording your Terminal history.

Access Your Terminal History From Anywhere

Now, run any random commands to verify if it really works.

I ran the following commands:

clear
pwd
uname -a
ls -l
touch test.txt

Now it is time to check what commands I have entered.

To do so,run:

bh

Sample output:

This command will display the last 100 commands by default. You can override the default limit by using “-n” flag.

To display only the last 10 commands, run:

bh -n 10

Display commands by using specific term

You can also display a specific command by using specific term, for example “ls”.

bh -n 10 “ls”

If you want to search for a specific command with a search term and run it at the same time, use “-i” flag as shown below.

bh -i "ls"

If you’ve run command more than one time, choose the command you want to run from the list and hit enter.

As you see above, I have run “ls” command three times.

Display the list of commands executed in a directory

To display the list of last commands you executed in the current working directory, use “-d” flag.

bh -d

Bashhub will display the most recently used commands.

Interactive search

The other notable feature of Bashhub is interactive search. It is similar to reverse search, you can invoke it by pressing either bh -i or ctrl + b keys.

Let us do interactive search.

$ bh -i
(bashhub-i-search): uname

The above command will search for for a command that has “uname” string. You can perform the interactive search in the current working directory using “-d” flag as shown below.

$ bh -i -d
(bashhub-i-search): ls

Viewing the details of a command

From interactive search, you can also view the detailed information of a command.

First launch the interactive search:

bh -i

Then choose the command from the list and hit “i” or “space bar” keys to display the selected command details.

Delete commands

You can also delete a particular command(s) from the Bashub database. To do so, launch the interactive search:

bh -i "ls"

Choose the command that you want to delete and hit “Backspace” or “Delete” keys from the keyboard.

Ignore particular commands from recording

This is another useful feature of the Bashhub utility. You can prevent a particular command that contains sensitive information like username or password from being recorded by bashhub.

To do so, just add #ignore at the end of the command.

Example:

$ uname -r #ignore

The above command” uname -r” will be recorded. Please note that if you’ve already configured your history to ignore space, Bash will not save the commands if run them with a space at the start of those commands. In that case, you don’t need to use “#ignore”.

Disable recording commands

If you want Bashhub record the commands, you can turn it by running the following command:

bashhub off

The commands won’t be recorded anymore until you turn it on.

Please remember this only affects the current bash session by default. To disable recording of all sessions globally, run:

bashhub off --global

To turn on Bashhub recording again. run:

bashhub on

Update Bashhub

Just rerun the installation command to update Bashhub. Also, run “bashhub update” command to update it.

Access Bashhub from a different system

Please note that you don’t need to run “bh” in the same system itself. Since all commands are stored in Bashhub’s database, you can view all your Terminal history from any system. Make sure you have installed Bashhub client on the system and login with the registered Email id and the password.
