Quick Save Alias - Version 1.0.2

Used to quickly add, remove, change aliases in Linux shell which will be persisted for future use automatically.

Note: This feature will be applied only for the particular user where it is installed.

Installing:

To install the script for the session, copy the following code to ~/.bashrc or ~/.bash-profile :

# Install QuickSaveAlias for the session
[ -e ~/quicksavealias.sh ] && source quicksavealias.sh -install

Hint: You can copy the file to home directory and make the file hidden by prefixing by period and then install as below

# Install QuickSaveAlias for the session
[ -e ~/.quicksavealias.sh ] && source .quicksavealias.sh -install

Un-installing:

Just remove the entry added for installing the feature in ~/.bashrc or ~/.bash-profile .

Note:

To reuse the aliases created, across multiple installations, multiple users and multiple linux machines, have a backup of the file ~/.bash-aliases and copy it to the home directory before installing the script as above.
To remove all the new aliases created just delete ~/.bash-aliases file.
