/usr/bin/staprun [-v] [-w] [-V] [-h] [-u] [-c cmd ] [-x pid] [-u user] [-A|-L|-d] [-C WHEN]
[-b bufsize] [-R] [-r N:URI] [-o FILE [-D] [-S size[,N]]] MODULE [module-options]
-v Increase verbosity.
-V Print version number and exit.
-h Print this help text and exit.
-w Suppress warnings.
-u Load uprobes.ko
-c cmd Command 'cmd' will be run and staprun will
exit when it does. The '_stp_target' variable
will contain the pid for the command.
-x pid Sets the '_stp_target' variable to pid.
-N pid Sets the '_stp_namespaces_pid' variable to pid.
-o FILE Send output to FILE. This supports strftime(3)
formats for FILE.
-b buffer size The systemtap module specifies a buffer size.
Setting one here will override that value. The
value should be an integer between 1 and 4095
which be assumed to be the buffer size in MB.
That value will be per-cpu in bulk mode.
-L Load module and start probes, then detach.
-A Attach to loaded systemtap module.
-C WHEN Enable colored errors. WHEN must be either 'auto',
'never', or 'always'. Set to 'auto' by default.
-M INTERVAL Enable monitor mode.
-d Delete a module. Only detached or unused modules
the user has permission to access will be deleted. Use "*"
(quoted) to delete all unused modules.
-R Have staprun create a new name for the module before
inserting it. This allows the same module to be inserted
more than once.
-r N:URI Pass N:URI data to tapset functions remote_id()/remote_uri().
-D Run in background. This requires '-o' option.
-S size[,N] Switches output file to next file when the size
of file reaches the specified size. The value
should be an integer greater than 1 which is
assumed to be the maximum file size in MB.
When the number of output files reaches N, it
switches to the first output file. You can omit
the second argument.
-T timeout Specifies upper limit on amount of time reader thread
will wait for new full trace buffer. Value should be an
integer >= 1, which is timeout value in ms. Default 200ms.
-F fd Specifies file descriptor for module relay directory
MODULE can be either a module name or a module path. If a
module name is used, it is searched in the following directory:
/lib/modules/6.18.60-r0-gcp-6.18/systemtap

stap -p4 -e 'probe begin { printf("Hello World!n"); exit() }'
/home/user/.systemtap/cache/85/stap_8553d83f78c_265.ko
Here is a very basic example of how to use staprun.staprun /home/user/.systemtap/cache/85/stap_8553d83f78c_265.ko
Hello World!
Run staprun with the pathname to the module as an argument.
