# kons — Work-around KDE 4 / Konsole asynchronous silliness
|
|||
|
|
#
|
|||
|
|
# Version 2009.01-blf (YYYY.MM-INITIALS). # Created by Brian Foster <bria...@innova-card.com>
|
|||
|
|
# Released under the GPL. # # KDE 4 / Konsole is asynchronous. That is, ‘konsole -e COMMAND’ exits
|
|||
|
|
# immediately instead of when the terminal session completes (as was
|
|||
|
|
# the case in KDE 3, and still is the case with other terminaks, such
|
|||
|
|
# as xterm(1)). Consequently, it's hard to determine when <COMMAND>
|
|||
|
|
# completes, which is something that is often required (e.g., when
|
|||
|
|
# <COMMAND> is an “external editor” for Kmail or similar).
|
|||
|
|
#
|
|||
|
|
# In theory, the ‘--nofork’ option prevents this, but that's unreliable,
|
|||
|
|
# often resulting in the opaque complaint (the ‘4763’ is the PID of some
|
|||
|
|
# process (not sure what process?)):
|
|||
|
|
#
|
|||
|
|
# <unknown program name>(4763)/: KUniqueApplication: Can't setup D-Bus service. Probably already running.
|
|||
|
|
#
|
|||
|
|
# Hence this script, which attempts to run Konsole synchronously.
|
|||
|
|
# The usage is (intended to be) identical to Konsole. The script does
|
|||
|
|
# not exit until the <COMMAND> exits. Furthermore, the exit status is
|
|||
|
|
# nominally that of <COMMAND>. Hence, instead of:
|
|||
|
|
#
|
|||
|
|
# konsole -e COMMAND # # simply using (<SCRIPT> is the name of this script, e.g., ‘kons’):
|
|||
|
|
#
|
|||
|
|
# SCRIPT -e COMMAND # # works-around the KDE 4 asynchronous Konsole problem.
