Unable to create a bare git repository

My git version is 1.5.0.6.

I want to create a bare git repository called sample.git.

I tried all sorts, but it failed:

Try 1:

Gives a usage statement but no git created

git init --bare sample.git 
usage: git-init [--template=<template-directory>] [--shared] 

Try 2: (using git-init not git init)

$ git-init --bare sample.git
usage: git-init [--template=<template-directory>] [--shared]

Try 3: Create a directory sample and then run same command, but still same output and git repository not created.

Please help me.

Firstly, upgrade your git. Version 1.5 is positively ancient.

If you can't upgrade, I'd just create a normal git repository, then manually convert it to a bare repo. An ordinary git repo will contain a '.git' directory. This can be your "bare" repo. Rename this directory to whatever you like. (You'll probably want to mv .git ../myrepo.git).

Then you have to tell git that it is a bare repo. Do this by adding bare = true to the config file in the [core] configuration section.
