> Troubleshooting tool for tracing system calls.

|
|
|
|
- Start tracing a specific process by its PID:
|
|
|
|
`strace {{[-p|--attach]}} {{pid}}`
|
|
|
|
- Trace a process and filter output by system call [e]xpression:
|
|
|
|
`strace {{[-p|--attach]}} {{pid}} -e {{system_call,system_call2,...}}`
|
|
|
|
- Count time, calls, and errors for each system call and report a summary on program exit:
|
|
|
|
`strace {{[-p|--attach]}} {{pid}} {{[-c|--summary-only]}}`
|
|
|
|
- Show the time spent in every system call and specify the maximum string size to print:
|
|
|
|
`strace {{[-p|--attach]}} {{pid}} {{[-T|--syscall-times]}} {{[-s|--string-limit]}} {{32}}`
|
|
|
|
- Start tracing a program by executing it:
|
|
|
|
`strace {{program}}`
|
|
|
|
- Start tracing file operations of a program:
|
|
|
|
`strace -e trace=file {{program}}`
|
|
|
|
- Start tracing network operations of a program as well as all its forked and child processes, saving the output to a file:
|
|
|
|
`strace {{[-f|--follow-forks]}} -e trace=network {{[-o|--output]}} {{trace.txt}} {{program}}`
