strace: Tracks and displays system calls associated with a running process.
- Summary
- The strace program intercepts and records the system calls called and
received by a running process. Strace can print a record of each
system call, its arguments and its return value. Strace is useful for
diagnosing problems and debugging, as well as for instructional
purposes.
Install strace if you need a tool to track the system calls made and
received by a process.
