Recently, I switched from a Powerbook to a Macbook, and to copy my files from one to the other, I used a pen drive. Since my pen drive has a FAT file system, it treats everything as being executable. This, however, is not the case on a UNIX-like file system like OS X. In order to save myself the hassle of manually chmodding thousands of files, I wrote this Ruby script:
Ruby
require 'find'
require 'fileutils'
# Append to/remove from this list as necessary
Plain = ['php', 'txt', 'jpg', 'jpeg', 'gif', 'png', 'html', 'pdf', 'css', 'mp3', 'zip', 'tar.gz', 'tar', 'htm', 'psd', 'ai', 'ptg', 'cgi.pl', 'sphp', 'svn-base', 'default'].collect do |ext|
".#{ext}"
end.freeze
# Append to/remove from this list as necessary
Executable = ['pl', 'rb', 'cgi', 'sh'].collect do |ext|
".#{ext}"
end.freeze
$num_chmodded = 0
def chmod_and_puts( cmd )
puts cmd
system cmd
$num_chmodded += 1
end
def chmodder( start_dir )
num_skipped = 0
num_plain = 0
num_executable = 0
Find.find( start_dir ) do |path|
unless File.symlink?( path )
if FileTest.file? path
if is_plain? path
chmod_and_puts "chmod 644 \"#{path}\""
num_plain += 1
elsif is_executable? path
chmod_and_puts "chmod 755 \"#{path}\""
num_executable += 1
else
num_skipped += 1
end
elsif File.directory? path
chmod_and_puts "chmod 755 \"#{path}\""
num_executable += 1
else
num_skipped += 1
end
else
num_skipped += 1
end
end
puts "----------------------------------------------"
puts "Chmodded #{$num_chmodded} total:"
puts "\tExecutable: #{num_executable}"
puts "\tPlain: #{num_plain}"
puts "Skipped #{num_skipped} files/directories/symlinks"
end
def get_extension( path )
File.extname( path ).downcase
end
def is_executable?( path )
extension = get_extension( path )
if Executable.include? extension
true
else
false
end
end
def is_plain?( path )
extension = get_extension( path )
if Plain.include? extension
true
else
false
end
end
chmodder( '.' )
This goes through all the files and directories within the directory from which you run the script and chmods non-executable files to 644 (read+write on User, read on Group and Other) and executable files to 755 (read+write+execute on User, read+execute on Group and Other). If you're unfamiliar with the chmod command, you might want to read my beginning Linux guide.

You realize that:
if Executable.include? extension
true
else
false
end
is equivalent to simply:
Executable.include(extension)
right?
:)
ugh, somehow the ‘?’ (question-mark) after the include was excluded from my post, no idea why :(
