How commands are executing ?

Hi Folks,

I have a small doubt, the binary commands under /bin and /sbin as well as other path binary files, if you peek deep into that, you can find the difference in the way of normal perl programming and some commands will be like binary files. how are the commands executing like the difference in perl scripting and binary files.

CLEAN-BINARY-FILES(1)						   User Commands					     CLEAN-BINARY-FILES(1)

NAME
clean-binary-files - remove a third party binaries (JARs) from an upstream archive SYNOPSIS
clean-binary-files {[-f {-, instructions_file}], [-e exclusion_file] [-l]} [-a archive_file] [-d custom_jar_map] [-n] [-p] [-s] OPTIONS
-f The instructions file, specifying which files to keep and which to remove -e The exclusions file, specifying special binary files that are to be preserved, or non-binary files that are to be removed. -l Only list instructions (to put in instructions file), do not delete anything. -a Archive file on which actions will be performed, as opposed to current directory -d A custom jar map file (has priority over the generic one). -n No symlinks (i.e. only clean jars, don't run build-jar-repository afterwards) -p Preserve original file names (-p to build-jar-repository) -s Silent mode. Won't output commands during cleanup -f The instructions file, specifying which files to keep and which to remove -e - The exclusions file, specifying special binary files that are to be preserved, or non-binary files that are to be removed. -l - Only list instructions (to put in instructions file), do not delete anything. -a - Archive file on which actions will be performed, as opposed to current directory -d - A custom jar map file (has priority over the generic one). -n - No symlinks (i.e. only clean jars, don't run build-jar-repository afterwards) -p - Preserve original file names (-p to build-jar-repository) -s - Silent mode. Won't output commands during cleanup EXAMPLES
Suppose there is a vanilla tarball abc-1.tar.gz with some binary files (jars) in it. In the source repo, we would want a clean copy without any jars. We can use the scripts to achieve this: To generate an instructions file: clean-binary-files -e <exclusion file> -l -a abc-1.tar.gz > instructions This creates an 'instructions' file, which contains info on what stays and what goes. Then, one can run: clean-binary-files -f instructions -n -a abc-1.tar.gz This would create abc-1-clean.tar.gz for uploading into jpp/fedora/etc. repositories with no binary (jar) files. Alternatively, if you have a vanilla tarball, you can clean and create symlinks in it's place all at once by: clean-binary-files -e <exclusion file> -d <custom_jar_map> -a abc-1.tar.gz Note: If the -a <file> is not given to clean-binary-files(1), all actions are performed on current directory.
