[Locomotive-users] [Req] : project snapshot (zip)

[Adam Salter]

I just finished writing a shell script like this which uses Ruby! :)

Probably a bit complicated, but maybe not...
Requires "session" rubygem


archive.rb
--------------
#!/usr/bin/env ruby

#
# Make an archive of the directory from command line
#

require "FileUtils"
require 'rubygems'
require 'session'

begin

   if ( ARGV[1] )
     raise SystemCallError, "not a directory" if !File.directory? ARGV 
[1]
     dir = File.basename(ARGV[1])
     date = File.new(dir).mtime.strftime("_%d-%m-%Y")
     arch_file = '_archive/'+dir+date+'.zip'

     FileUtils.mkdir '_archive' if !File.directory? '_archive'
     FileUtils.rm arch_file if File.exists? arch_file

     sh = Session.new
     stdout, stderr = sh.execute "tar -czvf #{arch_file} #{dir}"
     raise SystemCallError, "#{stderr}" if sh.exitstatus != 0
     case ARGV[0]
     when 'cp'
     when 'mv'
         FileUtils.rm_r dir
     end
   else
     my_string = <<END_OF_STRING

USAGE: archive [ cp | mv ] dir

   cp - Copies the chosen directory into the '_archive' directory,  
renaming it by the modification date.
   mv - Moves the chosen directory into the '_archive' directory,  
renaming it by the modification date.

END_OF_STRING
     puts my_string
   end

rescue SystemCallError
   $stderr.print "Archive failed: " + $! + "\n"
end
