31 [-Ha] [-C COLUMN,...] [-u USER] [PATTERN ...]
32 List stored keys. If PATTERNs are given, only list keys whose labels match
36 -H Don't show the column headings (useful for scripts).
37 -C COLUMN,... Select the columns to show.
38 -a Show keys owned by all users.
39 -u USER Show keys owned by USER.
41 A COLUMN spec consists of a column name and an optional column width; the
42 separator character determines the behaviour as shown below. The default is
44 NAME=WIDTH Exact width: truncate the contents to fit if necessary.
45 NAME:WIDTH Minimum width: spill into the next column (breaking the
46 alignment) if necessary.
47 NAME+WIDTH Minimum width: if a value won't fit then make the entire
51 flags Various flags for the key. (Unset flags are shown as \`.')
52 R key has recovery information
53 ! key nub needs recovery
54 label The key's label (relative to its owner).
55 profile The key's profile name.
56 recov Recovery key labels, comma-separated.
