Bug 28798

Summary:	mail(1) with a pager (more) requires fg/Ctrl-Z/fg to restore after suspension with Ctrl-Z

Description str 2001-07-08 00:40:03 UTC

This happens on a vanila 4.3-RELEASE system.
/usr/bin/mail is used to view
a message that is longer then one screen and the pager (more) is used
If you suspend mail (via Ctrl-Z) in the middle of the paged message,
when you bring it to the foreground (fg) - the screen does not
get  restored, and  the program does not accept any commands.
The only way to bring mail back, is to repeat Ctrl-Z and fg.
I haven't seen this behavior before (4.0 and prior).
Is this somehow related to the new "more"  ?

Fix: 

None available.
Workaround:
Ctrl-Z again and fg again restores the program.
How-To-Repeat: Use mail(1) to read a message that is longer than the screen length,
so the pager is used. Suspend the programs with Ctrl-Z.
Try "fg" to restore it.

To submitter: is this still a problem with modern versions of FreeBSD?

Apparently still a problem.

Comment 5 Mikolaj Golub 2008-12-07 09:02:48 UTC

The problem is reproducible under fbsd6.2 and fbsd6.3 in xterm, but I can't
reproduce it in console.

Under fbsd7.0 fg/Ctrl-Z/fg works ok for me in xterm too.
