regex - Replace slash in Bash

Question

Let's suppose I have this variable:

DATE="04/Jun/2014:15:54:26".

Therein I need to replace / with / in order to get the string:

"04/Jun/2014:15:54:26".

I tried tr as follows:

echo "04Jun2014:15:54:26" | tr '' '\/'

But this results in: "04Jun2014:15:54:26".

It does not satisfy me. Can anyone help?

Answer 1

No need to use an echo + a pipe + sed.

A simple substitution variable is enough and faster:

echo ${DATE////\/}

#> 04/Jun/2014:15:54:26
