Decide the directory for command execution
- Determine which directory on your machine should be accessible for CLI operations. You will set this as the value for
ALLOWED_DIR.
Choose which commands and flags are permitted
- List the commands you wish to allow (for example:
ls,cat,pwd,echo). This will be your value for ALLOWED_COMMANDS.
- List the command-line flags you wish to allow (for example:
-l,-a,--help,--version). This will be your value for ALLOWED_FLAGS.
(Optional) Set advanced restrictions
- If needed, set a maximum command length with
MAX_COMMAND_LENGTH.
- Set the number of seconds before a command times out with
COMMAND_TIMEOUT.
- If you want to allow shell operators like
&&, set ALLOW_SHELL_OPERATORS to true. By default, it should be false for security.
