[-S SORTBY] [-P PATH]... [-p PID]... [-U COLUMNS] [--seccomp-bpf]
{
-p PID | [-DDD] [-E VAR=VAL]... [-u USERNAME] PROG [ARGS] }
or: strace -c[dfwzZ] [-I N] [-b execve] [-e EXPR]... [-O OVERHEAD]
[-S SORTBY] [-P PATH]... [-p PID]... [-U COLUMNS] [--seccomp-bpf]
{
-p PID | [-DDD] [-E VAR=VAL]... [-u USERNAME] PROG [ARGS] }
General:
-e EXPR a qualifying expression: OPTION=[!]all or OPTION=[!]VAL1[,VAL2]...
options: trace, abbrev, verbose, raw, signal, read, write, fault,
inject, status, quiet, kvm, decode-fds
Startup:
-E VAR=VAL, --env=VAR=VAL
put VAR=VAL in the environment for command
-E VAR, --env=VAR
remove VAR from the environment for command
-p PID, --attach=PID
trace process with process id PID, may be repeated
-u USERNAME, --user=USERNAME

Tracing:
-b execve, --detach-on=execve

-ff, --follow-forks --output-separately

-I INTERRUPTIBLE, --interruptible=INTERRUPTIBLE
1, anywhere: no signals are blocked
2, waiting: fatal signals are blocked while decoding syscall (default)
3, never: fatal signals are always blocked (default if '-o FILE PROG')
4, never_tstp: fatal signals and SIGTSTP (^Z) are always blocked
(useful to make 'strace -o FILE PROG' not stop on ^Z)
Filtering:
-e trace=[!]{

--trace=[!]{
[?]SYSCALL[@64|@32|@x32]|[?]/REGEX|GROUP|all|none}
trace only specified syscalls.

%memory, %net, %process, %pure, %signal, %stat, %%stat,
%statfs, %%statfs
-e signal=SET, --signal=SET
trace only the specified set of signals
print only the signals from SET
-e status=SET, --status=SET
print only system calls with the return statuses in SET
statuses: successful, failed, unfinished, unavailable, detached
-P PATH, --trace-path=PATH
trace accesses to PATH
-z, --successful-only
print only syscalls that returned without an error code
-Z, --failed-only
print only syscalls that returned with an error code
Output format:
-a COLUMN, --columns=COLUMN
alignment COLUMN for printing syscall results (default 40)
-e abbrev=SET, --abbrev=SET
abbreviate output for the syscalls in SET
-e verbose=SET, --verbose=SET

-e quiet=SET, --quiet=SET
suppress various informational messages
messages: attach, exit, path-resolution, personality, thread-execve
-e kvm=vcpu, --kvm=vcpu
print exit reason of kvm vcpu
-e decode-fds=SET, --decode-fds=SET
what kinds of file descritor information details to decode
details: dev (device major/minor for block/char device files)
path (file path),
pidfd (associated PID for pidfds),
socket (protocol-specific information for socket descriptors)
-i, --instruction-pointer

descriptors in addition to paths
Statistics:

Miscellaneous:
-d, --debug enable debug output to stderr
-h, --help print help message
