Pulling the first and last character/number from a string.

Let's say I have a word "foobar23" in a file, and I want to pull the first "f" and last "3" character out of the world, how would I accomplish that?

# cat file
foobar23

I want the output to be:

f3

(use the button right of the post (attention sign) to report the spam)

bash:
Code:
> cat file
foobar23
> var=`cat file`
> echo $var
foobar23
> echo ${var:0:1}${var: -1}
f3

Note that the space in ${var: -1} is important.
