 1 | # history-db
 2 | 
 3 | ## About
 4 | 
 5 | History DB is very similar to the shell-sink project (https://github.com/joshuacronemeyer/shellsink), but with the goal of being as easy to install, and as portable, as possible.
 6 | 
 7 | It consists of 2 parts
 8 | 
 9 |  - A server component built on a very simple mysql database and php installation
10 |  - A pair of bash functions that can be included in a bashrc file to automatically post commands run to the web server, and to download and sync the local bash history file with the server.
11 | 
12 | ## Configuration
13 | 
14 |  - Create the MySQL database on your central server using `db/schema.sql` and grant your web server appropriate access to that database.
15 | 
16 |  - make the `web` directory accessible on a web server with php and php-mysql. 
17 | 
18 |  - Modify the php files to include a new download password (for download.php) and the MySQL connection parameters (for both `download.php` and `index.php`)
19 | 
20 |  - include `bash/bashrc-funcs` in your bashrc somehow, either with a `source` statement, or copy+paste
21 | 
22 |  - add the following to your bash $PROMPT_COMMAND variable:
23 |  `post_history; history -a`
24 | 
25 | 
26 | 
27 | 


--------------------------------------------------------------------------------
/bash/bashrc-funcs:
--------------------------------------------------------------------------------
1 | function post_history { LAST_COMMAND=$(history 1 | sed -e 's/^ *[0-9]* *[0-9]*-[0-9]*-[0-9]* *[0-9]*:[0-9]*:[0-9]* *- *//g'); curl -d hostname="$HOSTNAME" -d command="$LAST_COMMAND" http://yourserver.example.tld/history/; } 
2 | function get_history {  echo -n "enter password: "; read -s HISTPASS; history -c; rm ~/.bash_history; curl -s http://yourserver.example.tld/history/download.php?passwd=$HISTPASS > ~/.bash_history; history -r; }
