Where to find sources of UNIX commands???
Dear friends,
I believe that all unix commands are programs which are written in c language, please correct me if I am wrong. Now suppose that I want to see the c source of common commands like echo, ls, mkdir etc, where I can I find the source, linux is open source I believe, so the source for indivisual commands should be available.
Thanks

createlang
CREATELANG(1) PostgreSQL Client Applications CREATELANG(1)
NAME
createlang - define a new PostgreSQL procedural language
SYNOPSIS
createlang [ connection-options... ] langname [ dbname ]
createlang [ connection-options... ] --list | -l dbname
DESCRIPTION
createlang is a utility for adding a new programming language to a PostgreSQL database. createlang can handle all the languages supplied
in the default PostgreSQL distribution, but not languages provided by other parties.
Although backend programming languages can be added directly using several SQL commands, it is recommended to use createlang because it
performs a number of checks and is much easier to use. See CREATE LANGUAGE [create_language(7)] for additional information.
OPTIONS
createlang accepts the following command-line arguments:
langname
Specifies the name of the procedural programming language to be defined.
[-d] dbname
[--dbname] dbname
Specifies to which database the language should be added. The default is to use the database with the same name as the current sys-
tem user.
-e
--echo Displays SQL commands as they are executed.
-l
--list Shows a list of already installed languages in the target database (which must be specified).
-L directory
Specifies the directory in which the language interpreter is to be found. The directory is normally found automatically; this option
is primarily for debugging purposes.
createlang also accepts the following command-line arguments for connection parameters:
-h host
--host host
Specifies the host name of the machine on which the server is running. If host begins with a slash, it is used as the directory for
the Unix domain socket.
-p port
--port port
Specifies the Internet TCP/IP port or local Unix domain socket file extension on which the server is listening for connections.
-U username
--username username
User name to connect as
-W
--password
Force password prompt.
ENVIRONMENT
PGDATABASE
PGHOST
PGPORT
PGUSER Default connection parameters.
DIAGNOSTICS
Most error messages are self-explanatory. If not, run createlang with the --echo option and see under the respective SQL command for
details. Check also under psql(1) for more possibilities.
NOTES
Use droplang(1) to remove a language.
createlang is a shell script that invokes psql several times. If you have things arranged so that a password prompt is required to connect,
you will be prompted for a password several times.
EXAMPLES
To install pltcl into the database template1:
$ createlang pltcl template1
