This script is used to wrap executables in order to analyse how they are called by other scripts, daemons etc. It will log all parameters and the environment of the originally called executable to a log file for inspection. How to use: =========== Let's suppose you want to wrap the executable 'foo': First approach -------------- 1. rename the original executable # cd /where/the/original/lives # mv foo foo.orig 2. copy executable_wrapper where 'foo' was before # cp executable_wrapper /where/the/original/lives/foo Second approach --------------- 1. make sure that the 'executable_wrapper' script will be executed instead of the executable 'foo': # cd /usr/local/bin # ln -s ~/path_to/executable_wrapper foo Note that by convention /usr/local/bin comes first in $PATH on Unix systems 2. make the original executable 'foo' available as 'foo.orig' # cd /usr/local/bin # ln -s /bin/foo foo.orig You can also set the name of the original executable in the variable original_exec_name inside the 'executable_wrapper' script if you need to do so. 3. output will be logged to /tmp/foo.log.XXXXXX, where 'XXXXX' will be some random string. You can also set the log name in the variable 'log_name' inside the 'executable_wrapper' script
