Writing content to file

We learnt about creating files with the touch command but these are just empty files. Let's go on to add some content to this file.

The echo command we discussed earlier can be used to write stuff to a file.

Typically, the text passed to the echo commands, other wise known as the argument gets printed to the stdout, however we can "pipe" this value to a file

echo "unless you are permitted to share!!" > info.txt

If the file does not exist when you pipe the content of stdout or stderr to a file, the file will be created with the intended content.

You can also append additional content to an already existing file. To do this, 'pipe' the new content to the file with a double arrow.

echo "unless you are permitted to share!!" >> info.txt
