trim spaces

[pandithiru]

Need help to trim spaces on either side of the string.

example:
var = " UNIX is always FUN! "

I need to trim the spaces before and after the string and my variable should have the following

var="UNIX is always FUN!"

I tried the tr cmd but did not work as expected.

Thanks in advance,
pandithiru

OK, how about

echo "      UNIX is always FUN!          " |  sed -e "s/^ *//g" -e "s/ *$//g"

or save a few bytes:

var=$(echo "  UNIX is always FUN! " | sed 's/^ *//g;s/ *$//g')

let the shell do the job

var=" UNIX is always FUN! "
echo $var
