Installation of scripts and binaries, the scripts

A way to release code in an organized fashion

As always, your own your own if the script mess your files up, I just provide the info you are responsible for what you do with it

Read this description to see how the scripts are used.
Described in this document are the mapping file, installation script and example makefile.

You have two files, the script and a file that maps the script to their destination.
The format of the mapping file is:

 destinationserver TAB path to file from ~/ TAB destinationpath TAB flag if the file is a binary or not TAB additional text
 

The mapping file

 stats   theFiles/project1/calculateRevenue   /opt/calc/   binary   ERROR: This is a binary file, you need to install it with 'make'
 stats   theFiles/project1/stat_scripts/gen_stats.sh      /opt/statscripts/
 calc    theFiles/project23/something.sh                  /some/dir/
 

The source code

 #
 # This script is used to ftp a file from the local directory to
 # the proper directory on the production machine
 # It will also write date,userid,hostname,targetfile,sourcefile
 # into a logfile, as well as sent with email
 #
 # At the moment it works like this:
 #
 # 1. Go to the directory with the file you have changed
 # 2. Run this script with the the full path as command argument
 # 3. Done, unless you get error messages
 #
 # Sample session:
 # $ whoami
 # user12
 # $ cd ~/theFiles/project1/stat_scripts
 # $ install.ksh -m "fixed bugs" $PWD/gen_stats.sh
 # Installing:
 # calvin:/home/user12/theFiles/project1/stat_scripts/gen_stats.sh
 # at:
 # hobbes:/opt/statscripts/
