I would agree with using perl, but you can split the input out using awk
by defining the filed separator, for example the following code:

echo name=value | awk '{FS='='; print $2}'

yields:

value

Using bash or ksh, you can get at it as follows:

name=value

# comes in as $1, so..

echo ${1#*=}

# yields

value
