Generate Junk Files
The other day I was testing benchmarks for a delete script. I needed to create files with various file sizes. More specific, 1,000,000 files with 5K per file. A while ago I found this great snippet on StackOverflow to generate a junk random string:
junk = (("%%0%dX" % (junk_len * 2)) % random.getrandbits(junk_len * 8)).decode("hex")
I’ve wrapped that around to make a utility function and snippet:
import os, random, sys # This tool takes 3 parameters # # testing # # Example: # # testing dan 100 500 def createLocalDirectory( directoryName ): if not os.path.exists( directoryName ): os.makedirs( directoryName ) folderName = sys.argv[1] how_many_files = int(sys.argv[2]) junk_len = int(sys.argv[3]) createLocalDirectory( folderName ) for i in range( 0, how_many_files ): junk = (("%%0%dX" % (junk_len * 2)) % random.getrandbits(junk_len * 8)).decode("hex") path = folderName + "/" + str(i) + ".txt" f = open( path, 'w' ) f.write( junk ) print f f.close()
