Comments on the stty info page:
`stty' prints or changes terminal characteristics, such as baud rate.
Synopses:
stty [OPTION] [SETTING]...
(Might as well say [LINE SETTING]...
to match how you talk below, or change the below.)
stty [OPTION]
If given no line settings, `stty' prints the baud rate, line
discipline number (on systems that support it), and line settings that
have been changed from the values set by `stty sane'. By default, mode
No, stty sane changed columns from 86 to 88 and plain stty didn't report it.
reading and setting are performed on the tty line connected to standard
input, although this can be modified by the `--file' option.
P.S., one has to do
stty -a|perl -pwle 'if(/;/){s/; /\n/g;s/;//}else{s/ /\n/g}'
to get output suitable for diff(1)... perhaps add an option to print
one setting per line.
