Learn
A file can be manipulated in a variety of ways. In fact, Unix built upon this to create an operating system where everything is treated as a file. Therefore learning some simple command line file operations is crucial:
- New empty files are commonly created using the
touch
command. - The contents of a directory can be listed using the
ls
command. - A string of text can be output to the terminal using the
echo
command. This is useful in coordination with the>
operator that redirects the text output to a file. - A file can be output and read using the
cat
command. - A file can be deleted using the
rm
command.
