Vxworks Command Cheat Sheet |verified| -

ti – Shows detailed, verbose information about a specific task (stack usage, options, TCB).

This cheat sheet covers commonly used VxWorks commands, but it's not exhaustive. VxWorks provides a wide range of commands and options, and you may need to consult the official documentation or seek guidance from experienced developers for more specific tasks.

| Command | Description | |---------|-------------| | semShow | List all semaphores | | semGive <semId> | Give a binary/counting semaphore | | semTake <semId> [,<timeout>] | Take a semaphore | | msgQShow | Show message queues | | msgQSend <qId>, <msg>, <size>, <timeout>, <prio> | Send to message queue | | msgQReceive <qId>, <buffer>, <size>, <timeout> | Receive from queue | | eventReceive <events> [,<timeout>] | Wait for events |

sp , [arg1], ..., [arg9] – Spawns a new kernel task executing the specified function. vxworks command cheat sheet

The VxWorks kernel shell allows users to monitor and debug real-time processes through a command-line interface. In this environment, strings must be quoted, and multiple arguments are separated by commas.

: Available in newer versions (VxWorks 7) for symbols and files.

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

Uses standard C function call syntax, requiring parentheses and trailing semicolons for multiple arguments. Prompt: Typically ends with -> . Example: taskShow(0, 1); Modern Command Shell (Cmd) ti – Shows detailed, verbose information about a
