Quick file rename with Groovy
Recently I have been learning the syntax of regular expression. Now regular expression + (Groovy of course) become part of my 'toolset' for my daily computer usage. A very quick and easy demonstration of what I meant here..
Lets say you downloaded you favourite TV shows and you wish to rename all your .avi files into a standardize format.
E.g. You have the following files
D:\Heroes\Heroes.S01E12.HDTV-LOL.avi
D:\Heroes\heroes.S01E13.HDTV.XviD-FPN.avi
D:\Heroes\Heroes.S01E14.HDTV-LOL.avi
instead of renaming the file one-by-one, use the following code
Your files should be rename to
D:\Heroes\Heroes.S01E12.avi
D:\Heroes\Heroes.S01E13.avi
D:\Heroes\Heroes.S01E14.avi

def sourceFolder = 'D:\\Heroes'
new File(sourceFolder).eachFile {
def p = /[hH](eroes)\.S?0?(\d)E?(\d\d?).*/
if ( it.getName() ==~ p ) {
def s = (it.getName() =~ p).replaceFirst('H$1.S0$2E$3.avi')
println "${it.getName()}\n${it.getParent().toString()}\\${s}\n"
assert it.renameTo(new File("${it.getParent().toString()}\\${s}"))
}
}
Your files should be rename to
D:\Heroes\Heroes.S01E12.avi
D:\Heroes\Heroes.S01E13.avi
D:\Heroes\Heroes.S01E14.avi
