[Nottingham] "unescaping" the wildcard character for xargs

[Rory Holland]

Let's say I have a command which outputs line-delimited filenames with
wildcards in them.

For example:

/home/alice/*
/home/bob/*
/home/eve/*

I'm trying to cat these files, but using the following doesn't work

<command> | xargs cat

This is because the * character is being interpreted literally, so I
get the following error on each line:

cat: /home/alice/* : no such file or directory.

Nothing in man xargs seems to help. What can I do?
