what does =~ means in if test statement.
 

Hello Guys,

I am trying to modify a shell script according to my requirements & i am seeing an if statement like below:

if [[ "$i" =~ "you are guest " ]] ; then
echo "Welcome Guest"

Now, can someone please tell me what does that =~ test condition means???

It isn't causing any problems to me in modifying the script but just curious to know what it is exactly..

Thx in advance.

This should help.

thx man!!

Mark the thread as solved.
