Hm, it returns success in either case. Have to check its error output instead.

Code:
TMP=`mktemp`
if wget -N http://server/file 2> "$TMP"
then
        if grep -q "Not retrieving" "$TMP"
        then
                echo "Already up to date"
        else
                echo "New file retrieved"
        fi
else
        echo "Couldn't download file"
fi
rm -f "$TMP"

[edit] A smarter way might be by what wget itself does, check timestamps.

Code:
TMP=`mktemp`
# Set temp file to the same timestamp as current file
touch --reference=outputfile "$TMP"

if wget -N http://path/to/file
then
        # Compare timestamps.  If outputfile is newer, it got updated
        if [ outputfile -nt "$TMP" ]
        then
                echo "New file downloaded"
        else
                echo "No new version"
        fi
else
        echo "Error retrieving file"
fi
# Don't clutter up /tmp
rm -f "$TMP"

shtool path [-s|--suppress] [-r|--reverse] [-d|--dirname] [-b|--basename] [-m|--magic] [-p|--path path] str [str ...] DESCRIPTION
This command deals with shell $PATH variables. It can find a program through one or more filenames given by one or more str arguments. It prints the absolute filesystem path to the program displayed on "stdout" plus an exit code of 0 if it was really found. OPTIONS
The following command line options are available. -s, --suppress Supress output. Useful to only test whether a program exists with the help of the return code. -r, --reverse Transform a forward path to a subdirectory into a reverse path. -d, --dirname Output the directory name of str. -b, --basename Output the base name of str. -m, --magic Enable advanced magic search for ""perl"" and ""cpp"". -p, --path path Search in path. Default is to search in $PATH. EXAMPLE
# shell script awk=`shtool path -p "${PATH}:." gawk nawk awk` perl=`shtool path -m perl` cpp=`shtool path -m cpp` revpath=`shtool path -r path/to/subdir` HISTORY
The GNU shtool path command was originally written by Ralf S. Engelschall <rse@engelschall.com> in 1998 for Apache. It was later taken over into GNU shtool. SEE ALSO
