[kde] Opening Konsole with Multiple Pre-loaded Tabs
While pursuing how to rename KDE's Konsole terminal emulator tabs programmatically I came across many people wanting to open and preload multiple Konsole tabs, the most-popular example being multiple SSH sessions. There is a way to do this with D-Bus, described in this Linux Journal article [1]. I have wanted to open Konsole with multiple tabs after logging in, as part of an alternative to KWin's all-or-nothing approach to resuming sessions after login. But for some years Konsole has had a built-in method to open with multiple preloaded tabs, without using DBUS at all. Problem is, there are only hints at how to do this on the web and I only had a cobbled-together idea of how to use it and it only partly worked for me. I finally got it to work correctly after reading the Konsole source [2] for the function and would like to share how I use it to help fill in a little empty spot in the KDE documentation space. I have a K Menu item configured to execute this command: konsole --tabs-from-file /home/jerome/bin/konsole_Work where /home/jerome/bin/konsole_Work is a text file that looks like this: title: Work;; workdir: ~/work;; command: vi _desk title: root;; command: sudo -i sysfiles title: bss-gate;; command: sshto gateway When Konsole starts it will open 3 tabs doing 3 different things: in Work I edit a file after cd-ing to a directory, in root I run a script which edits a file, and in bss-gate I run a script to ssh to my gateway server. Each line of konsole_Work specifies a tab to open using up to 4 fields specifying how it is to open. Fields are delimited with ';;' and a field name must have a ':' appended. title: a name for this tab, tab default if blank workdir:working directory, ~ if blank profile:a Konsole profile to use, the default if blank command:a command to run You must have one of profile or command. I only use one Konsole profile so I don't have experience with that option. This article is at http://blogs.bss.ab.ca/clippings.htm and any updates I make will be there.

[kde] term config prolem
Greetings; Now, I took my sig off, is it still spam. Even with the sig, its not spam. Running Ubuntu 12.04.2 LTS, with enough kde pulled in to get kmail (which won't even start & no one has ever seen that error) the next biggest item stopping me from swapping drives and rebooting to it, is the fact that as the #1000 user, I cannot configure the Konsole. I can, no errors are generated when I close the edit window, but my changes are not there when I re-open the edit current profile 3 seconds later. Does anyone have a magic twanger to allow me to configure the Konsole to work as I need it? For instance, I do software for a legacy machine, and need at least 100k lines of history I can scroll back through looking for build errors. With a 1000 line default limit, 99% of a nitros9 build scrolls out of the buffer forever. I have 8Gb of ram, so there's little excuse for such a style cramping limit. Thanks all.

IIRC, konsole uses memory upto a certain point for scrollback, but
uses /tmp file-on-disk after that. (definitely if you select "unlimited scroll".
(e.g. lsof shows:
konsole 3877 dowdy 86u REG 254,6 896364 80
/tmp/kde-dowdy/konsolecr3877.tmp
(about 20 or so such lines, probably one per TAB)
if i switch from 1,000 fixed lines to unlimited (no tmpfiles open before)
For every character, i think (IIRC) konsole used about 3 bytes of disk space
(to hold
display attributes and the like)
For 1,000 lines at 80char/line that'd be about 1/4MB
for 100K lines that'd be about 25MB. that's still not tremendous,
but if you have lots of terms and especially unlimited scrollback
and a small /tmp, you could run into trouble.
I've seen some users with unlimited scrolling taking minutes to
scroll back to the beginning if they failed to regularly logout.
(these are folks that stay logged in for months at a time :-( )
So, not sure if Konsole honors ${TMPDIR} or not, but i'm guessing that these
are opened referential to kde path "tmp"
$ kde4-config --path tmp
/tmp/kde-dowdy/
so, you might need to change kde4-config to point to SharedMem by setting
KDETMP and/or TMPDIR via something like:
tmpfs_dir=${tmpfs_dir:-/dev/shm}
TMPDIR=$(mktemp -d ${tmpfs_dir}/${USER}.$(date +%Y-%m-%d).) \
|| { echo "failed to make temp directory, aborting" ; exit 1 ;}
readonly TMPDIR
export TMPDIR
export KDETMP="${TMPDIR}"
in a KDE Autostart directory script (or dotfile, or...)
prior to starting any konsole (multithreaded, so the first you start will
take precedent)
I'm just *this* far from replacing 'konsole' with a symlink to xfce Terminal,
(xfce4-terminal on Debian Wheezy)
which has many of the same features, but none of the misfeatures/bugs of
konsole.
(at least that i've found yet) (well, VTE, the engine xfce4-terminal uses does
use /tmp/vte* for scrollback buffering, even at 1,000 lines, or even 80, but
at least when you cut/paste, you get what you see, not a bunch of blanks at
the end of the line most of the time)

I was unaware of that. Good to know. Thanks. (Not that it particularly matters for me, since TMP is on tmpfs here anyway, meaning it's all memory, but I've 16 gigs to play with and don't stay logged in / that/ long, neither do I use the unlimited scrollback option, I had to look but it's 50 Kline, and I seldom have more than a half dozen terms open.) -- Duncan - List replies preferred.

I'd guess it's file perms somewhere along the line, probably on $KDEHOME/ share/config/konsolerc [1]. Ensure its UID/GID are set correctly and that it's writable by your user. Of course I know some of your kmail history from earlier posts, but a bit after kmail akonadified, when I was jumping thru hoops to retrieve yet another lost mail due to akonadi, I asked myself why I had to deal with that, and decided I didn't, so now I don't. I'm very happy on claws-mail now. (And BTW, claws-mail has user-side script extensibility as a deliberate feature, so I expect you'd get along with it quite well too. The only downside is that switching can be a pain, but I'm /so/ glad I did, here.) [1] If the var is unset, $KDEHOME defaults to ~/.kde as shipped by kde, but some distros change that to ~/.kde4 or something similar. -- Duncan - List replies preferred. No HTML msgs.
