If the `groupadd` command is not executable due to insufficient permissions, you should check its location and permissions. Start by locating the command. Use the `which` command followed by `groupadd` to identify its path, as shown below:

“`
$ which groupadd
“`

This command will output the path of the `groupadd` command, such as `/usr/sbin/groupadd`. Next, ensure that the command has executable permissions by using the `ls` command with the `-l` option:

“`
$ ls -l /usr/sbin/groupadd
“`

If the output does not include the “x” permission, indicating that it is not executable, you can make the command executable by executing the following command:

“`
$ sudo chmod +x /usr/sbin/groupadd
“`

Solution 3: Adjusting shell configuration
If you are encountering the “groupadd command not found” error while using an alternative shell, such as `zsh`, it is likely a matter of shell configuration. To fix this, determine the shell startup file for your specific shell (e.g., `~/.zshrc` for `zsh`) and add the following line:

“`
alias groupadd=’command groupadd’
“`

By defining an alias, your shell will recognize the `groupadd` command even if it is not included in the default configuration.

Solution 4: Insufficient privileges for non-root users
If you are logged in as a non-root user and are unable to execute the `groupadd` command, it is likely a deliberate restriction set by system administrators. Only users with administrative privileges or those assigned specific permissions are typically allowed to create new user groups. Contact your system administrator if you require the ability to utilize this command.
