    -c -- count time, calls, and errors for each syscall and report summary
    -f -- follow forks, -ff -- with output into separate files
    -F -- attempt to follow vforks, -h -- print help message
    -i -- print instruction pointer at time of syscall
    -q -- suppress messages about attaching, detaching, etc.
    -r -- print relative timestamp, -t -- absolute timestamp, -tt -- with usecs
    -T -- print time spent in each syscall, -V -- print version
    -v -- verbose mode: print unabbreviated argv, stat, termio[s], etc. args
    -x -- print non-ascii strings in hex, -xx -- print all strings in hex
    -a column -- alignment COLUMN for printing syscall results (default 40)
    -e expr -- a qualifying expression: option=[!]all or option=[!]val1[,val2]...
       options: trace, abbrev, verbose, raw, signal, read, or write
    -o file -- send trace output to FILE instead of stderr
    -O overhead -- set overhead for tracing syscalls to OVERHEAD usecs
    -p pid -- trace process with process id PID, may be repeated
    -D -- run tracer process as a detached grandchild, not as parent
    -s strsize -- limit length of print strings to STRSIZE chars (default 32)
    -S sortby -- sort syscall counts by: time, calls, name, nothing (default time)
    -u username -- run command as username handling setuid and/or setgid
    -E var=val -- put var=val in the environment for command
