AFAIK all the terminal emulators shipped with Solaris (e.g. "dtterm", "xterm", "gnome-terminal" and "konsole"), the native Solaris console on SPARC and the Solaris/x86 console support that sequence (AFAIK it is from vt100 or earlier (vt52 ?!)). This specific bug is only a sporadic one and AFAIK a bug in ksh93 (note that this is a different issue than the SPARC-specific problem reported in https://mailman.research.att.com/pipermail/ast-users/2006q3/001303.html ; on SPARC the "multiline" option seems to be totally screwed in ksh93r+_alpha_20060724... ;-( ) ... > I don't think that it would be compatbile to make this the > default at compile time, but you could put this into /etc/profile > for terminals that support \E[A. I didn't made this a default at compile time.

Mhhh... I never used "globstar" and ksh93 on SuSE Linux 10.0 seem to have it "off": -- snip -- $ set -o | fgrep glob globstar off noglob off -- snip -- April/Mike - any opinions ? ---- Bye, Roland -- __ . . __ (o.\ \/ /.o) roland.mainz at nrubsig.org \__\/\/__/ MPEG specialist, C&&JAVA&&Sun&&Unix programmer /O /==\ O\ TEL +49 641 7950090 (;O/ \/ \O;)
