Ruby implementation Batch add prefix code sharing _ruby Topic

Recently I got a lot of pictures from the designer, the results are 1.png,2.png such file name, they also need to make these files into a readable file name, do not want one to be modified, so wrote a simple script to achieve a lot of multiple files to add prefix operation, later modified a bit, share.

Code

Copy Code code as follows:

#!/usr/bin/env Ruby
# Encoding:utf-8

Srcdir= Argv[0]
prefix= Argv[1]
Pattern = ' * '
Pattern = argv[2] if argv.size = = 3

Dir[srcdir + '/' + pattern].each{|child|
ChildName = File.basename (Child)
Destchildname = prefix + childname
Destchild = Child.gsub (ChildName, Destchildname)
System ' MV%s '%s '%[child, Destchild]
}

How to use

The method used

1.ruby add_prefix_files.rb dest_folder prefix pattern
2.dest_folder the underlying directory for the required operation, and not always directly to the parent directory
3.prefix must prefix name suggested end with _ End
4.pattern Optional, if not filled in as Dest_folder Direct sub file (including directories), otherwise the application provided pattern matching

Using the sample

Adds a test_ prefix to all files in the current directory.

Copy Code code as follows:

~/rubydir/tools/add_prefix_files.rb./test_

res/drawable-hdpi/all PNG files to the current directory, adding test_ prefixes

Copy Code code as follows:

~/rubydir/tools/add_prefix_files.rb./test_ "Res/drawable-hdpi/*.png"
