in exercise 8 of lmpthw i.e the cut command section, author has asked to try this command:
ls −l | cut −d ’ ’ −f 5−7
i hit that in my terminal to see what it does. now i am wondering if it changes the original files, like it said, ‘it cuts the part of lines from the files’. so i am afraid if i have done any damage to my original files. do those parts get permently deleted from them? if so what shall i do to restore back in their own place?
the ss of the output on my terminal is attached here for the reference.
please explain what did i just do with that command. thank you.
