So I’ve recently gotten into scripting in ruby and with a couple of scripts you really can save yourself a lot of tedious work in the future. Here’s one i wrote that does a batch rename of all files in a given folder and its subfolders. You can do either of the following:
Enter 3 parameters:
- input directory
- search string
- replacement string
Or just enter 2 parameters in which case the search string will be removed from all files:
- input directory
- search string
Remember, to enter the parameters in that order, <input dir> <search string> [<replacement string>].
#!/usr/bin/ruby
# Dmitry Nedospasov
# Batch Rename
# 2 parameters: batchrename.rb <input dir> <search string>
# <search string> will be completely removed from all occurances
# 3 parameters: batrename.rb <input dir> <search string> <replacement string>
# all occurances of <search string> will be replaced with <replacement string>
require 'ftools'
def parseargs(arguments, stdin)
# puts arguments
dir = arguments[0]
oldExt = arguments[1]
newExt = arguments[2]
puts dir
puts oldExt
puts newExt
if oldExt == nil or dir == nil
puts 'Please enter atleast the first 2 parameters: '
puts ' <input directory> <search string> [<replacement string>]'
else
convertFromTo(dir,oldExt,newExt)
end
end
def convertFromTo(dir, oldExt, newExt)
files = Dir.entries(dir)
files.each do |f|
next if f == '.' or f == '..'
fullPath = dir + '/' + f
# fullPath = fullPath.gsub(' ','\ ')
if File.directory?(fullPath)
puts 'Found directory: ' + fullPath
convertFromTo(fullPath, oldExt, newExt)
else
if newExt == nil
newName = fullPath.gsub(oldExt,'')
else
newName = fullPath.gsub(oldExt,newExt)
end
if fullPath != newName
puts fullPath + ' -> ' + newName
File.rename(fullPath,newName)
end
end
end
endparseargs(ARGV, STDIN)
and what you should get is something like this
