|
- Start tracing a specific [p]rocess by its PID:
|
2015-03-21 01:01:05 +01:00
|
|
|
|
|
|
|
|
`strace -p {{pid}}`
|
|
|
|
|
|
2024-02-20 01:28:47 +11:00
|
|
|
- Trace a [p]rocess and filt[e]r output by system call:
|
2015-03-21 01:01:05 +01:00
|
|
|
|
2024-02-20 01:28:47 +11:00
|
|
|
`strace -p {{pid}} -e {{system_call,system_call2,...}}`
|
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
|
|
|
|
2024-10-16 17:53:30 +11:00
|
|
|
- Show the [T]ime spent in every system call and specify the maximum string [s]ize to print:
|
2016-01-04 03:17:07 +09:00
|
|
|
|
2024-10-16 17:53:30 +11:00
|
|
|
`strace -p {{pid}} -T -s {{32}}`
|
2016-08-22 07:59:39 -04:00
|
|

|
|
- 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}}`
|
2024-02-20 01:28:47 +11:00
|
|
|
|
|
|
|
|
- Start tracing network operations of a program as well as all its [f]orked and child processes, saving the [o]utput to a file:
|
|
|
|
|
|
|
|
|
|
`strace -f -e trace=network -o {{trace.txt}} {{program}}`
|
