Remove / at the end of a string if it exists

Hey guys, Can sed or another command be used to examine a path such as

/home/test/blah/blah

and check to see if the last character is a "/" and if so remove it

So this is what should happen:

/home/test/blah/blah

nothing happens, this is ok

/home/test/blah/blah/

the "/" at the end is removed and the string becomes

/home/test/blah/blah

Thanks all

Yes:

$ p=/home/test/blah/blah/
$ printf "%s\n" "${p%/}"
/home/test/blah/blah
$ p=/home/test/blah/blah
$ printf "%s\n" "${p%/}"
/home/test/blah/blah
3 
echo "/home/test/blah/blah/" | sed 's/\/$//'
/home/test/blah/blah
4 
var=/home/test/blah/blah/
echo $var| sed 's%/$%%'
echo ${var%%/}

This one works well, thanks everyone for your help!

Actually radoulov's solution (also posted in a variant by danmero) is superior.

Since the pattern can only match a single character, you only need one %:

newvar=${var%/}
