'Can I use wget to check , but not download

Can I use wget to check for a 404 and not actually download the resource? If so how? Thanks

wget

Solution 1:^[1]

There is the command line parameter --spider exactly for this. In this mode, wget does not download the files and its return value is zero if the resource was found and non-zero if it was not found. Try this (in your favorite shell):

wget -q --spider address
echo $?

Or if you want full output, leave the -q off, so just wget --spider address. -nv shows some output, but not as much as the default.

Solution 2:^[2]

If you want to check quietly via $? without the hassle of grep'ing wget's output you can use:

wget -q "http://blah.meh.com/my/path" -O /dev/null

Works even on URLs with just a path but has the disadvantage that something's really downloaded so this is not recommended when checking big files for existence.

Solution 3:^[3]

You can use the following option to check for the files:

wget --delete-after URL

Solution 4:^[4]

Yes easy.

wget --spider www.bluespark.co.nz

That will give you

Yes, to use the wget to check , but not download the target URL/file, just run:

wget --spider -S www.example.com
