The command "compgen -ac ${ls}" is a combination of two separate commands - "compgen" and "ls". Let's break it down:
-
"ls" is a command used to list files and directories in the current directory. It is not necessary in this context and can be removed to make the command "compgen -ac".
-
"compgen" is a command used to generate possible completions for a given word or command. It is often used in conjunction with shell tab completion to suggest available options or commands.
In the given command "compgen -ac", it has the following options:
- "-a" option stands for "aliases" and lists all defined shell aliases.
- "-c" option stands for "commands" and lists all available commands.
When this command is executed, it will list all the defined aliases and available commands in the current shell environment.
