XARGS - help passing results - 3inchpython - Aug-03-2019 System = RHEL 7 Python v = 2.7 Using the code below, I am using file_list and random_choice to randomly select one filename from a given DIR of many files #!/usr/bin/env python # -*- coding: utf-8 -*- import random import subprocess file_list = ['/MyDir/bin/messages/messageone.txt', '/MyDir/bin/messages/messagetwo.txt', '/MyDir/bin/messages/messagethree.txt', '/MyDir/bin/messages/messagefour.txt', '/MyDir/bin/messages/messagefive.txt', '/MyDir/bin/messages/messagesix.txt', '/MyDir/bin/messages/messageseven.txt', '/MyDir/bin/messages/messageeight.txt', '/MyDir/bin/messages/messagenine.txt', '/MyDir/bin/messages/messageten.txt' ] strOut = random.choice(file_list) print strOutThe random file selected output currently looks like this: /MyDir/bin/messages/messagesix.txt Using XARGS (or some other means) I would like to take that output and construct and execute a simple CP command, which effectively copies the randomly selected file to another directory with filename message.txt, something like the below. cp strOut /MyDir/bin/message.txt Normally, I would post my attempted code, but my attempts have been feeble and miserable failures at best. Any help would be greatly appreciated. RE: XARGS - help passing results - buran - Aug-03-2019 if you want to invoke system command like cp take a look at subprocess module in the simplest form import subprocess subprocess.run(['cp', source, destination]) # replace source and destination with your own or assign values beforehandalso you can use pure python to copy files |
