In NetLab 7d it covered copying, moving, and removing files and directories. To display the
contents of a text file use the cat command. Use the wc command to display information about a
file. To translate a set of characters to another set of characters use the tr command (tr a-z A-Z
< “file name”) (Translate lower case text to upper case). If you want to remove duplicate lines
from a file use >>. I would use this lab in the real world if I wanted to make a file backup in a
directory, you can use the cp command and mv to a different directory.
