fetchme is a cli tool for safe aliasing. This package allows aliasing of long commands without using the default bash aliasing.

Why use fetchme?

• Safe aliasing commands, no more accident in overriding a existing command
• Easy to use

Make sure python 3.6 is installed on your machine, if not, click here to follow the instructions on installation.

Then install the latest version of fetchme via pip:

$ pip3 install fetchme

Once you install the package, there will be a configuration file .fetchmerc generated in your home directory, and this is where you put all your aliases.

fetchme comes with 3 default commands: edit, set and remove.

edit command opens up the .fetchmerc file in an editor. If you have configured your preferred editor in the environment variable EDITOR, the preferred editor will be launched. The default editor is vim if the environment variable is not being configured.

Usage:

fetchme edit [OPTIONS]

Example:

$ fetchme edit

This command is for setting an alias to a long command.

Usage:

fetchme set [OPTIONS] CONTENT

Example:

$ fetchme set ssh="ssh -i /path/to/my/key/file root@123.43.678.678"

The CONTENT argument is where you set your alias as key=value pair, it is recommended that you quote the command that is to be aliased, like so in the example.

An additional line will be added to .fetchmerc file after the set command is being executed.

[fetchme]
ssh = ssh -i /path/to/my/key/file root@123.43.678.678

Options:

--override, -o: flag, override an existing alias, this flag must to be past when you

This command is to remove an existing alias.

Usage:

fetchme remove [OPTIONS] NAME
