"${1}" is the long form of "$1". It is the first positional parameter the script got. If you call a script like this:

Code:
$ ./somescript.sh first second third

then inside ./somescript.sh the variable "$1" would be set to "first", the variable "$2" would be set to "second" and "$3" would be set to "third". So this line is asking if the first parameter to the script equals "pre".

I hope this helps.

seeded-in-ubuntu - Determine whether a package is safe to upload during a freeze SYNOPSIS
seeded-in-ubuntu [options] package... DESCRIPTION
Lists all the current daily images containing the specified packages. Or whether the package is part of the supported seed. If it isn't on an image, it should be safe to upload. During the final freeze, one should avoid packages in the supported seed too. An index of the current manifests is downloaded from UbuntuWire. OPTIONS

This is faster than source packages, as otherwise we must query LP to determine the binary packages that every specified source package builds. -u URL, --data-url=URL URL for index of seeded packages. Default: UbuntuWire's service at http://qa.ubuntuwire.org/ubuntu-seeded-packages/seeded.json.gz. -h, --help Display a help message and exit EXAMPLES
