NAME

       tmperamental - avoid writing to /tmp

SYNOPSIS

       tmperamental cmd arg1 arg2 ...

DESCRIPTION

       tmperamental  uses  a preloaded library that intercepts filesystem writes, and causes loud
       failures when writes are attempted on /tmp/*

       The idea here is by setting TMPDIR and friends, it catches programs  in  the  act  of  not
       respecting such env-vars.

USAGE

       Prefix the command you want to run with tmperamental and it should cause it to abort if it
       ever tries to write anywhere within /tmp.  This is pretty brutal,  so  you  probably  only
       want to use it for testing.

ENVIRONMENT

       If TMPDIR is unset, tmperamental will set it automatically to $HOME/tmp.

       tmperamental  uses  LD_PRELOAD to load a custom library libtmperamental.so that intercepts
       library calls.

LIMITATIONS

       tmperamental only catches writes to /tmp at shared object library calls using the standard
       libc  interface.   A  statically-compiled program that makes system calls directly will be
       able to write to /tmp without being intercepted.
