The xlsatoms(1) utility lists the interned atoms. By
default, all atoms starting from 1 (the lowest atom value defined
by the protocol) are listed until unknown atom is found. If an
explicit range is given, xlsatoms(1) will try all atoms in
the range, regardless of whether or not any are undefined.
This option specifies the X server to which to connect.
-formatstring
This option specifies a printf(3)-style string used
to list each atom <value,name> pair, printed in that
order (value is an unsigned long and name is a
char *). The xlsatoms(1) utility will supply a
newline at the end of each line. The default is
%ld\t%s.
-namestring
This option specifies the name of an atom to list. If the atom
does not exist, a message will be printed on the standard
error.
-range [low]-[high]
This option specifies the range of atom values to check. If
low is not given, a value of 1 is assumed. If high is
not given, xlsatoms(1) will stop at the first undefined atom
at or above low.
