|
| 4 | # clean it up using the 'rm' command.
|
| 5 | #
|
| 6 | # $ rm file # removes file
|
| 7 | # $ rm file1 file2 # removes files
|
| 8 | # $ rm -r dir/ # recursively removes files and folders
|
| 9 | # $ rm -rf dir/ # forces the previous command
|
| 10 | # $ rm * # removes all the files within the current folder,
|
| 11 | # saves time on not having to input every file
|
| 12 | # $ rmdir dir/ # removes an empty directory

|
| 15 | # example below
|
| 16 | #
|
| 17 | # $ rm folder/*.txt
|
| 18 | #
|
| 19 | # This command will rm all the files within folder/ that end with .txt
|
| 20 | # meaning anyfile that ends with .c, .sh, or has no dot endings will
|
| 21 | # not be deleted.
|
| 22 | #
|
| 23 | # $ rm a*z
|
| 24 | #
|
| 25 | # The above command will remove any combination of files that start with
|
| 26 | # 'a' and end with 'z'. Including files directly named 'az' with nothing
|
| 27 | # inbetween.

| 29 | # For your next exercise, remove the custom folder you created earlier

|
| 32 | # way possible when typing. Don't change anything in the code snippet
|
| 33 | # below
|
| 34 | rm -rf 06_folder

|
| 41 | # from above without deleting the folder. Test out different ways,
|
| 42 | # maybe combine arguments to accomplish this. Do not add more or
|
