Hello, i have quite a problem to manage and i cant really manage to do so myself so im seeking for help here. What i need to do is to get % of file copied somehow displayed (or captured to variable even better). So on windows im using cmd's "copy" command. copy s.txt b.txt /z Displays nice percentages of progress. Now.. i could add >output.txt at the end to get that percentages to file.. but thats quite a spam of them and thats not what i want to achieve. Generally i tried with backticks and with open command and i cant really get it to work. In best case i received 100% at the end of copy but i dont know how to execute copy and read how much % there is. Any help with making it happening would be greatly appreciated.
