 # profile
+This project aims to create an advanced bash profile. It includes some aliases,
+a customized prompt and several functions for different purposes. It's mostly
+targeted to system administrator but might satisfy some regular users.
 
-bash profile repository
+## 1. Getting started
+Download and extract (or use git clone) the profile archive into your home
+directory. You will have to modify your ~/.bashrc and/or ~/.profile file to add
+at the end (preferably):
+```
+source <installpath>/profile/profile.sh
+```
+
+It's not recommended to load that profile in /etc/profile as the users' .bashrc
+files might interfere with some aliases and functions defined in profile.
+
+## 2. What's the purpose?
+profile is giving access to numerous functions, aliases and to an advanced
+prompt. Here is a non-exhaustive list of what we have:
+- A bar style prompt with hour, execution time and exit code of the last
+command;
+- clean: erase after confirmation any backup file, possibly recursively;
+- dpkgs: search for the given pattern in the installed packages name;
+- expandlist: usefull in scripts, it expand any expression using wildcards into
+the corresponding list of file and directories;
+- genpwd: generate one or more random secure password;
+- gpid: give the list of PID matching the given process name;
+- help: display the list of available function and basic use;
+- isipv4: tell if the given parameter is a valid IPv4 address;
+- isipv6: tell if the given parameter is a valid IPv6 address;
+- ku: kill all the processes owned by the given user name or ID;
+- mcd: create a directory and immediately move into it;
+- meteo: display weather forecast information;
+- ppg: look for the given patern in the running processes;
+- rain: console screensaver with rain effect;
+- rmhost: remove the given host (name or IP) to the list of SSH known host;
+- rmspc: in the current directory it replace all the spaces in filenames with a
+underscore caracter (or any other given in option);
+- setc: set locale on standard C;
+- setfr: set locale on French;
+- settrace: allow the debugging of any script by showing a backtrace in case of
+error;
+- setus: set locale on US English;
+- showinfo: display basic informations about the host;
+- ssr: root ssh login to the given host;
+- taz: a universal command to compress files and directories, possibly several
+at once;
+- utaz: a utility that smartly uncompress many archives at once, creating a
+directory only if needed;
+- ver: show profile version.
+
+## 3. Configuration
+Some functions might have configurable default behaviour. You can create a
+.profile.conf file to configure those default behaviour. You should have a look
+at the doc/.profile.conf.example to see the list of available options.
+
+## 4. Contact and more information
+### 4.1. New users
+This project is very new in terms of publication, and I have no idea of who will
+use it, if any does. If you use (or plan to use) ```profile```, I'll be very
+happy if you simply mail me to let me know, especially if you don't plan to
+contribute. If you plan to contribute, I'll be twice happier for sure!
+
+### 4.2. Bugs
+**profile** bug tracker is hosted on its Gitea instance. Check the
+https://git.geoffray-levasseur.org/fatalerrors/profile page. If you find a bug,
+you can also submit a bug report to the maintainer mail address mentioned at
+the end of that document. A bug report may contain the command line parameters
+where the bug happens, OS details, the module that trigger it, if any, and the
+log file containing the error. Cygwin users: please note that bash
+implementation in Cygwin triggers regularly bugs on advanced code that triggers
+nothing with Linux or BSD. Please do not send synthax error bug repports if you
+didn't test the same code in the same conditions using a real Unix.
+
+Please check the to-do list before sending any feature request, as it might
+have already be requested.
+
+### 4.3. How to contribute?
+You are free to improve and contribute as you wish. If you have no idea what to
+do or want some direction, you can check the [to-do list](./doc/todo.md),
+containing desired future improvements. Make sure you always have the latest
+development version before starting your work.
+
+It's heavily recommended to use git to obtain the latest copy of profile tree.
+Make sure your git configuration is correct in order to contribute. Please
+contact me to obtain push authorizations, or, if you want to submit a patch, you
+can send it by mail to the maintainer of init.sh.
+
+Code written in Python or Perl might be accepted as long as it's not mobilizing
+a lot of dependencies (forget big framework). Anything that need the
+installation of packages not provided in minimal Debian or CentOS installation
+will be probably rejected.
+
+If you want to make a financial contribution, please contact me by mail.
+
+### 4.4. License, website, and maintainer
+Everything except configuration files is licensed under BSD-3 license. Please
+check license file allong this one.
+
+Please check [https://www.geoffray-levasseur.org/profile](https://www.geoffray-levasseur.org/profile).
+Note that this website is still under construction and needs some more care.
+
+You can mail author to fatalerrors \<at\> geoffray-levasseur \<dot\> org.
