Quick Save Alias - Version 1.1.0

Used to quickly add, remove, change aliases and alias functions which will be persisted for future use automatically.

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

Alias Functions

Alias functions are functions with single line statements that can accept function arguments, stored as alias. For example,

dex='docker exec -it $1 /bin/bash'

This can be invoked as below:

dex my-docker-container:latest

Installatioin:

To install the script for the session,

• Download the file quicksavealias.sh file to your home folder.
• 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 Note: This can be placed elsewhere also if required. Please alter the above installation command appropriately.

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

• And then source that file (~/.bashrc or ~/.bash-profile) or re-login to use QuickSaveAlias.

Quick-Installation:

• To quickly install QuickSaveAlias:

curl -s https://raw.githubusercontent.com/loganathan001/QuickSaveAlias/master/install.sh | bash && source ~/.bashrc

• To quickly install QuickSaveAlias with basic aliases backup (my_aliases_backup/.bash-aliases):

curl -s https://raw.githubusercontent.com/loganathan001/QuickSaveAlias/master/install.sh | bash -s basic && source ~/.bashrc

• To quickly install QuickSaveAlias with some other aliases backup (my_aliases_backup/.bash-aliases-<some-other-backup>):

curl -s https://raw.githubusercontent.com/loganathan001/QuickSaveAlias/master/install.sh | bash -s <some-other-backup> && source ~/.bashrc

For Example:

curl -s https://raw.githubusercontent.com/loganathan001/QuickSaveAlias/master/install.sh | bash -s devops && source ~/.bashrc

Un-installation:

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.

Aliases:

  al                                      : Shortcut for 'alias'
  unal                                    : Shortcut for 'unalias'
  lsal                                    : Shorcut for 'alias -p' - used to list the aliases
  sval                                    : Saves all the aliases to '$BASH_ALIAS_FILE_PATH' for future usage.
  algrep [grep_options] GREP_PATTERN      : used to find the alias based on the grep pattern.

  lsfn                                    : list all alias functions
  fngrep [grep_options] GREP_PATTERN      : used to find the alias functions based on the grep pattern.

Examples:

  adal cdsvn 'cd ~/dev/svn/'          --  Safely Adds the alias 'cdsvn' without overwriting 
                                          and existing one and persist the changes.
  chal e3 '~/dev/eclipse3.6/eclipse'  --  Safely change the existing alias 'e3' to some other value 
                                          and persist the changes.
  rmal e3                             --  Removes the alias 'e3' 
                                          and persist the changes.
  cpal algrep ag                      --  Copies the 'algrep' alias to the new alias 'ag' 
                                          and persist the changes.
  mval sdiff sdf                      --  Renames the 'sdiff' alias to the new alias 'sdf' 
                                          and persist the changes.

  rmfn dlf                                        --  Removes the alias function and persists the changes.
