so a few days ago i logged on a sunOS/solaris 2.5[1] at work and
found only sh and ksh. after sending ksh thru' strings i see that its a
88 version not 93...which got me curious to test "delete-last-word" key(s)
... and i found that a particular combination (of meta[2], "alt", with w or
h) works okay after some T&E (trial and error). (i will post it later
today after i return from work.) ...that got me thinking about
the above problem.
anyway ... the "problem" seem to be confusion/ignorance about just
which key(s) generate the "meta" key. in TERM=cons25, "esc, h" does
the "delete-last-word" properly... which also happen to work in
${TERM:0:5}=xterm properly. it's just that "alt+h" also works in
a xterm (clone). and, let the truth be told, i was expecting "alt"
to be treated as "meta" key in ksh in console and didn't even
thought of using "esc"... guess i didn't read the man page carefully
at the time of the "problem", was too concentrated on description
of "M-h" -- which ... ummm ... clearly >gulp< states/implies that
"esc" generates the "meta" key...
sorry for the long confession style problem resolution ... i think
perlmonks.com's recent postings are getting to me.
[1] the sun os has various pieces of software containing references to both
solaris and sunOS.
[2] i use teraterm to telnet to it on ultraSparc ii and teraterm has the
option to use meta key, unlike tvnt iirc
