|
- Start tracing a specific process by its PID:
|
2015-03-21 01:01:05 +01:00
|
|
|
|
|
|
|
`strace -p {{pid}}`
|
|
|
|
|
2016-01-07 18:31:27 +01:00
|
|
|
- Trace a process and filter output by system call:
|
2015-03-21 01:01:05 +01:00
|
|
|
|
2018-10-29 12:14:25 +01:00
|
|
|
`strace -p {{pid}} -e {{system_call_name}}`
|
2015-03-21 01:01:05 +01:00
|
|
|
|
2016-01-07 18:31:27 +01:00
|
|
|
- Count time, calls, and errors for each system call and report a summary on program exit:
|
2015-03-21 01:01:05 +01:00
|
|
|
|
2015-03-21 02:02:35 +01:00
|
|
|
`strace -p {{pid}} -c`
|
2016-01-04 03:17:07 +09:00
|
|
|
|
2016-01-07 18:31:27 +01:00
|
|
|
- Show the time spent in every system call:
|
2016-01-04 03:17:07 +09:00
|
|
|
|
|
|
|
`strace -p {{pid}} -T`

|
|
|
- Start tracing a program by executing it:
|
2016-08-22 07:59:39 -04:00
|
|
|
|
|
|
|
`strace {{program}}`
|
2017-12-07 20:16:57 +01:00
|
|
|
|
|
|
|
- Start tracing file operations of a program:
|
|
|
|
|
|
|
|
`strace -e trace=file {{program}}`
|
