I have a variable and I need to test if it contain a formated value like this ……..-….-….-….-…………
the variable can contem any value in any format, and I need to test if the value is like 1572C097-4452-4495-8369-C7606F2C867E
I tried using sed
to retrieve the value from another variable
tguid=$(echo $i |sed 's/.*(........-....-....-....-............).*/1/')
But now, I dont have a clue how can I use if [] statement to guarantee if the variable tguid have the correct value?

You don’t need to use sed
. A conditional expression can test whether a string matches a regexp directly.
if [[ $i =~ .{8}-.{4}-.{4}-.{4}-.{12} ]] then echo It matches else echo It does not match fi
