SYNOPSIS

port echo
     [[portname | pseudo-portname | port-expressions | port-url]]

DESCRIPTION

port echo expands its argument list according to MacPorts' rules and prints a list of ports that match the expression given as argument. It can be useful to see what a pseudo-portname or a pseudo-portname selector (see port(1)) expands to.

If port echo doesn’t recognize an argument as port, it will still print it as-is. You cannot use port echo to check whether a port exists:

$ port echo nonexistentport
nonexistentport

EXAMPLES

Common use cases are:

port echo depends:zlib
port echo inactive
port echo obsolete
port echo requested
port echo leaves
port echo category:^mail$

Note that echo is usually not used to list outdated ports, since a separate action port-outdated(1) exists for that. port outdated has the advantage compared to port echo outdated that it gives the reason why MacPorts considers the port outdated.
