Key Takeaways

  • Crosh offers a command-line interface to manage Chrome OS.
  • Ctrl+Alt+T is used to open Crosh on a Chromebook.
  • Some Crosh commands may need Developer Mode enabled.

Using Crosh Commands

Crosh, standing for Chrome Shell, allows users of Chromebooks to access a set of command-line tools for diagnosing and resolving issues or configuring devices.

Basic Crosh Commands

To begin with Crosh, users can press Ctrl+Alt+T. This opens the Crosh terminal. Once there, typing help provides a list of basic commands. Use help_advanced for more complex commands. For understanding a specific command, help <command> proves useful. For instance, to exit Crosh, the command is exit.

Network and Connectivity

Chromebook users deal with network issues by using commands like ping which checks the connection to the internet. network_diag runs diagnostics on network issues. For a deeper look into network paths, tracepath maps the journey packets take to their destination. Changing network settings is possible using commands like set_apn and set_cellular_ppp.

System and Performance

Commands top and task manager allow users to monitor CPU and memory usage, identifying active processes. The storage_status command reviews the state of the device’s storage. Simple system checks are performed with battery_test and memory_test to check on the device’s health.

Advanced Utilities and Troubleshooting

For detailed system insights, systrace records system activity, while syslog retrieves system logs helpful in troubleshooting. Users employ packet_capture to diagnose complex network issues. With diagnostics, they can perform a suite of diagnostic tests on the hardware.

Device Management and Debugging

For device-specific information, commands like serial number retrieve the device’s identification. Users can manage Bluetooth with bt_console and troubleshoot with bluetooth debugging. If necessary, powerwash initiates a factory reset, returning the device to its default state.

Developer Tools

Developers tweak their Chromebooks with shell to access bash, a Unix command processor. For deeper system access, commands like sudo or su give superuser rights. Users enable developer mode to allow for more extensive system changes and manage Linux containers.

In conclusion, Crosh commands offer Chromebook users a powerful suite of tools for monitoring, troubleshooting, and configuring their devices, giving both casual and power users the ability to personalize and maintain their experience.
