compgen: List all aliases.
$ compgen -a
try on your machine
The command "compgen -a" is used in Unix-like operating systems to generate a list of all available aliases in the current environment. Here is a breakdown of each component of the command:
- "compgen": It is a built-in command in Unix-like shells (e.g., Bash) that generates possible completions for a given string. It is commonly used to auto-complete commands, options, filenames, etc.
- "-a": It is an option/flag provided to the "compgen" command in this case. "-a" stands for "aliases", instructing "compgen" to generate a list of aliases.
So, when you run "compgen -a", the command will produce a list of all aliases that have been defined in the current shell session. Aliases in Unix-like systems are shortcuts or alternate names for commands or command sequences, allowing users to create custom abbreviations for frequently used commands.
