Hi
In the tr man page and the --help command, a description of the '--'
command is missing.
In the info page it can be found where it says:
However, when ‘-’ is one of those characters, it can be tricky
because ‘-’ has special meanings. Performing the same task as
above but also removing all ‘-’ characters, we might try ‘tr -d
-axM’, but that would fail because ‘tr’ would try to interpret ‘-a’
as a command-line option. Alternatively, we could try putting the
hyphen inside the string, ‘tr -d a-xM’, but that wouldn’t work
either because it would make ‘tr’ interpret ‘a-x’ as the range of
characters ‘a’...‘x’ rather than the three. One way to solve the
problem is to put the hyphen at the end of the list of characters:
tr -d axM-
Or you can use ‘--’ to terminate option processing:
tr -d -- -axM
Thanks for great software!
