       fiu-run - a script to launch programs using libfiu


       fiu-run [options] program [program arguments]


       fiu-run  is  a  script to make it easier to launch programs using libfiu(3). It can enable
       failure points and start libfiu's remote control capabilities before starting  to  execute
       the program, avoiding the need to write a special launcher to inject failures.

       It  is  specially useful when used to inject failures in the POSIX/libc functions, because
       it does not require any program modifications.

       After launching programs with fiu-run, fiu-ctrl(1) can be used to enable and disable their
       failure points at runtme.

       For     additional     documentation,     go     to     the     project's    website    at


       -c command
              Run the given libfiu remote control command before executing the program (see below
              for reference).

       -x     Use  the  POSIX libfiu preload library, allows simulate failures in the POSIX and C
              standard library functions.

       -f ctrlpath
              Enable remote control over named pipes with  the  given  path  as  base  name,  the
              process  id will be appended (defaults to "$TMPDIR/fiu-ctrl", or "/tmp/fiu-ctrl" if
              "$TMPDIR" is not set). Set to "" to disable remote control over named pipes.

       -l path
              Path where to find the libfiu preload libraries. Defaults to the  path  where  they
              were installed, so it is usually correct.

       Remote  control  commands  are  of  the form "command param1=value1,param2=value2".  Valid
       commands are:

       'enable name=NAME'
              Enables the NAME failure point unconditionally.

       'enable_random name=NAME,probability=P'
              Enables the NAME failure point with a probability of P.

       All of the enable* commands can also optionally  take  failnum  and  failinfo  parameters,
       analogous to the ones taken by the C functions.


       The  following  will  run  the  fortune(1)  program  simulating  faults  in read() with 5%
       probability (note that the -x parameter is required in this case to enable failure  points
       in the POSIX and libc functions):

              fiu-run -x -c "enable_random name=posix/io/rw/read,probability=0.05" fortune

       By  running  it  multiple times you will see that sometimes it works, but most of the time
       you get different errors, resulting from the simulated failures.
