Create, update and delete files and directories

Creates a new directory test and then checks this with ls:

!mkdir tests

!ls

create-delete.ipynb           grep-find.ipynb.license
create-delete.ipynb.license   index.rst
dvc.list                      pipes-filters.ipynb
dvc.list.1                    pipes-filters.ipynb.license
file-system.ipynb             shell-variables.ipynb
file-system.ipynb.license     shell-variables.ipynb.license
grep-find.ipynb               tests

Then we create the file test_file.txt in this directory.

!touch tests/test_file.txt

!ls tests

test_file.txt

Now we change the suffix of the file:

!mv tests/test_file.txt tests/test_file.py

!ls tests

test_file.py

Now we make a copy of this file:

!cp tests/test_file.py tests/test_file2.py

!ls tests

test_file.py  test_file2.py

A directory with all the files it contains is also possible recursively with the -r option:

!cp -r tests tests.bak

!ls tests.bak

test_file.py  test_file2.py

Finally, we delete the directories tests and tests.bak again:

!rm -r tests tests.bak

!ls

create-delete.ipynb           grep-find.ipynb.license
create-delete.ipynb.license   index.rst
dvc.list                      pipes-filters.ipynb
dvc.list.1                    pipes-filters.ipynb.license
file-system.ipynb             shell-variables.ipynb
file-system.ipynb.license     shell-variables.ipynb.license
grep-find.ipynb

• -r recursively crawls other files and directories

• -np avoids crawling to parent directories

• -D targets only the following domain name

• -nH avoids creating a subdirectory for the websites content

• -m mirrors with time stamping, time stamping, infinite recursion depth, and preservation of FTP directory settings

• -q suppresses the output to the screen

cURL

Alternatively, you can use cURL, which supports a much larger range of protocols.

!curl -o dvc.list https://dvc.org/deb/dvc.list
