[SOLVED] How to extract last part of string in bash?

Issue

I have this variable:

A="Some variable has value abc.123"

I need to extract this value i.e abc.123. Is this possible in bash?

Solution

How do you know where the value begins? If it’s always the 5th and 6th words, you could use e.g.:

B=$(echo $A | cut -d ' ' -f 5-)

This uses the cut command to slice out part of the line, using a simple space as the word delimiter.
