Vxworks Command Cheat Sheet |best| Info

: Dynamically loads an object module file into memory and links its symbols.

Spawns a new task. Syntax: taskSpawn("name", priority, options, stackSize, entryPt, arg1...arg10) taskSuspend(taskId) C-Mode / Target Shell Suspends a specified task by its ID or name string. taskResume(taskId) C-Mode / Target Shell Resumes a suspended task. taskDelete(taskId) C-Mode / Target Shell

: Fills a block of memory with a specific byte or word value.

: Most are condensed into 1–2 pages, making them perfect for a second monitor or a taped-up reference next to a target board. Areas for Improvement vxworks command cheat sheet

d [address] : Displays the contents of memory at a specific hex address.

| Command | Description | Example | |---|---|---| | ls or ls "path" | List directory contents | ls "/fd0/" | | cd "path" | Change current working directory | cd "/usr/bin/" | | pwd | Print current working directory | pwd | | mkdir "dirname" | Create a new directory | mkdir "/newdir" | | rmdir "dirname" | Remove an empty directory | rmdir "/olddir" | | rm "filename" | Remove a file or directory | rm "test.txt" | | copy "src", "dest" | Copy a file | copy "a.txt", "b.txt" | | cp "src", "dest" | Alternative copy command with wildcard support | cp "*.c", "/backup/" | | cat "filename" | Display file contents | cat "/etc/config" | | dosFsShow device, level | Display dosFs volume configuration | dosFsShow "/fd0", 1 | : Dynamically loads an object module file into

: Traces the call stack (Task Trace) of a specified task, displaying the sequence of function calls leading to its current state.

: Use the arrow keys or h to see recent commands.

hostGetByName / inet_ntoa — DNS and address utilities.

: Inspects specific properties of kernel objects like semaphores, message queues, or tasks. Advanced Task Tracing taskResume(taskId) C-Mode / Target Shell Resumes a suspended

If you are debugging a driver, testing a board support package (BSP), or tuning a real-time task, you will eventually find yourself staring at the (also known as the C interpreter shell or Host shell ). Unlike a Linux bash shell, the VxWorks shell is a direct window into the kernel. You can execute C functions, inspect memory, change variables, and even spawn tasks on the fly.

Commonly used routines for setting execution breaks and stepping through code. b [address] : Sets a breakpoint at a specific address. bd [address] : Deletes a specific breakpoint. c : Continues execution from a breakpoint.
