# A list of 'Escape Sequences' that I will find useful.

# When using escape sequences with echo you have to use echo -e so that the backslash can be interpreted.

# \f - Formfeed - This has the benifit of clearing the screen, which could be used at the start of a script
# in order to give the user a clean slate, the downside is that the output of the scrip appears to show
# above the command prompt and not below it as normal.
echo -e '\f'


# \c surpresses the new line character that would happen naturally, so in this example below although it
# is split across numbers lines and commands the resulting output would be: " hello world " on one line.
echo "The line beneath this is actually two commands on two seperate lines, but the use of \c stops the newline character and makes it display on one line:"
echo -e 'hello \c'
echo 'world'

echo && echo # Just creates a empty space (couple of empty lines)

echo -e "hello \r\r\r\r"
echo "world"
