How to Use cd alias to navigate up the directory effectively

When you are navigating up a very long directory structure, you may be using
cd ..\..\ with multiple ..\’s depending on how many directories you want to go
up as shown below.
# mkdir -p
/tmp/very/long/directory/structure/that/is/too/deep
# cd /tmp/very/long/directory/structure/that/is/too/deep
# pwd
/tmp/very/long/directory/structure/that/is/too/deep
# cd ../../../../

# pwd
/tmp/very/long/directory/structure
Instead of executing cd ../../../.. to navigate four levels up, use one of the
following three alias methods:
Method 1: Navigate up the directory using “..n”
In the example below, ..4 is used to go up 4 directory level, ..3 to go up 3
directory level, ..2 to go up 2 directory level. Add the following alias to your
~/.bash_profile and re-login.
alias
alias

alias
alias
..="cd .."
..2="cd ../.."
..3="cd ../../.."
..4="cd ../../../.."
..5="cd ../../../../.."
# cd
/tmp/very/long/directory/structure/that/is/too/deep
# ..4
[Note: use ..4 to go up 4 directory level]
# pwd
/tmp/very/long/directory/structure/
Method 2: Navigate up the directory using only dots
In the example below, ..... (five dots) is used to go up 4 directory level.
Typing 5 dots to go up 4 directory structure is really easy to remember, as
when you type the first two dots, you are thinking “going up one directory”,
after that every additional dot, is to go one level up. So, use .... (four dots) to
go up 3 directory level and .. (two dots) to go up 1 directory level. Add the
following alias to your ~/.bash_profile and re-login for the ..... (five dots) to
work properly.
alias ..="cd .."

...="cd ../.."
....="cd ../../.."
.....="cd ../../../.."
......="cd ../../../../.."
# cd /tmp/very/long/directory/structure/that/is/too/deep
# .....
[Note: use ..... (five dots) to go up 4 directory level]
# pwd
/tmp/very/long/directory/structure/
Method 3: Navigate up the directory using cd followed by
consecutive dots
In the example below, cd..... (cd followed by five dots) is used to go up 4
directory level. Making it 5 dots to go up 4 directory structure is really easy to
remember, as when you type the first two dots, you are thinking “going up
one directory”, after that every additional dot, is to go one level up. So, use
cd.... (cd followed by four dots) to go up 3 directory level and cd... (cd
followed by three dots) to go up 2 directory level. Add the following alias to
your ~/.bash_profile and re-login for the above cd..... (five dots) to work
properly.

cd..="cd .."
cd...="cd ../.."
cd....="cd ../../.."
cd.....="cd ../../../.."
cd......="cd ../../../../.."
# cd /tmp/very/long/directory/structure/that/is/too/deep
# cd.....
[Note: use cd..... to go up 4 directory level]
# pwd
/tmp/very/long/directory/structure


Method 5: Navigate up the directory using cd followed by number
In the example below, cd4 (cd followed by number 4) is used to go up 4
directory level.
