[opensuse] BASH - better way to get total number of files matching glob??

by David C. Rankin

Guys, Doing a quick backup of config files (like .bashrc) from within bashrc and I need to find a better way to find the total number of files matching a glob in a directory. Currently I'm using: total=$(ls $budir/bashrc-* | wc -l) to determine how many copies I have in my bashrc.tar.bz2 backup + the new one I just copied to the backup location so I can determine the number to delete to just save the last 3 when I tar it up again. The ls | wc combination works fine, but I don't like the fact that there is a pipe in the middle of it. If there is a cleaner way to do it, let me know. P.S. Yes, I've added an alias too many times by doing "alias xzy='whatever' >~/.bashrc" -- thus the quick backup from within bashrc :p Of course if I would just remember >> I'd be just fine.... -- David C.

[opensuse] Midori on Suse 11.2

by Constant Brouerius van Nidek

Heard somewhere enthusiastic comments about the web browser Midori. Went to Yast and found it there. Installed it and wanted to have a look at this small web browser. Found it back in the menu and started it. And now I need help :) First info I received was: ----------- gcjwebplugin error: Failed to run/etc/alternatives/../../bin/java. For more detail rerun "firefox -g" in a terminal window ----------- Looked in /etc/alternatives/../../bin/java which did not help me much. Running firefox -g gave me Firefox and following message: ----------- nss-shared-helper NSS_USE_SHARED_DB enable ----------- Could not find nss-shared-helper. No idea where that would be hidden. Finally I ran midori in konsole which gave me following output. ---------- ~> midori /usr/src/packages/BUILD/icedtea6-1.7.3/plugin/icedteanp/IcedTeaNPPlugin.cc:1427: thread 0x80f5738: Error: Failed to spawn applet viewer: Failed to execute child process "/etc/alternatives/../../bin/java" (No such file or directory) *** NSPlugin Viewer *** ERROR: /usr/lib/browser- plugins/skypebuttons.so: cannot open shared object file: No such file or directory *** NSPlugin Viewer *** ERROR: /usr/lib/browser- plugins/skypebuttons.so: cannot open shared object file: No such file or directory *** NSPlugin Wrapper *** ERROR: failed to initialize plugin-side RPC client connection *** NSPlugin Wrapper *** WARNING: (/usr/src/packages/BUILD/nspluginwrapper-1.2.2/src/npw- wrapper.c:3156):invoke_NP_Initialize: assertion failed: (rpc_method_invoke_possible(g_rpc_connection)) *** NSPlugin Wrapper *** WARNING: (/usr/src/packages/BUILD/nspluginwrapper-1.2.2/src/npw- wrapper.c:3156):invoke_NP_Initialize: assertion failed: (rpc_method_invoke_possible(g_rpc_connection)) Illegal instruction -- Linux User 183145 using LXDE on a Pentium III , powered by openSUSE 11.2 (i586) Kernel: 2.6.31.12-0.2-desktop LXDE WM & KDE Development Platform: 4.4.3 (KDE 4.4.3) 12:08pm up 2 days 17:24, 2 users, load average: 1.22, 3.77, 4.11 -- To unsubscribe, e-mail: opensuse+unsubscribe(a)opensuse.org For additional commands, e-mail: opensuse+help(a)opensuse.org

[opensuse] Kindle for PC via WINE ?

by Regis Matejcik

Anyone had any luck getting "Kindle for PC" to run on OpenSuse via WINE ? There are several internet posts that reference a minor "tweak" to wine (essentially changing the winecfg to windows98 ) and "Kindle for PC" supposedly works fine. I've done the the winecfg tweak on both my OpenSuse 11.2 desktop and my Ubuntu laptop with similar results. The "Kindle for PC" program appears to install, an Icon shows up on the desktop, but when the icon is clicked - it tries to launch but crashes. -- Regis Matejcik Crescent Construction Company www.CrescentConstruction.com -- To unsubscribe, e-mail: opensuse+unsubscribe(a)opensuse.org For additional commands, e-mail: opensuse+help(a)opensuse.org

[opensuse] vmware and keyboard layout

by Roger Oberholtzer

i have a strange thing happening these days. when i start vmware, my keyboard layout gets messed up. for example, i am typing this message in evolution. i do not get caps, or various other characters as the shift key seems to have been disabled. this happens when i start vmware. oddly, the apps in vmware windows xp do get proper characters. i see this problem in kde. i cannot check the system console because alt-ctrl-fx also no longer work. stopping vmware does not correct the problem. i need to reboot. ok, i guess there is a command that could probably reset the keyboard. but why is this now happening the last statement was a question, but i can't type a question mark. this happens every time i run vmware. i think it started at some time when kde was updated. i am not certain. except that it was not when vmware was updated. anyone else have this odd behavior i have a swedish keyboard. adding the keyboard layout selector to the kde system tray does not help. some keys change as expected. but the shift key ans alt-ctrl seem gone until i reboot. -- Roger Oberholtzer OPQ Systems / Ramböll RST Ramböll Sverige AB Krukmakargatan 21 P.O.

[opensuse] openSUSE on SSD?

by C

Has anyone started seriously testing and tinkering with openSUSE on SSD drives? The prices are dropping and I'm thinking it's time to move over to SSD for my main drive - I'm thinking I'll do this around the release of 11.3. I've been doing some reading, and see a lot of conflicting info... in one place I see notes that you must set noatime and you cannot(should not) put the swap on the SSD drive.... among many others... like running a cron job to clear or write memory on a regular basis (something to that effect was discussed here, but without any clear reason why you'd need to so this or what was actually being doen.... at least not that I saw. Most of the rest of the information is at least 2 years old and mostly focuses on panic over the limited read/write cycles on SSDs... one camp says no problems, just install as usual... the other says no way.. disable this and that, and put home on a reg drive, and and and. So.. what's the concensus here? Just install as normal now? Treat the drives as a reg drive? Or handle with care and assume I'm venturing into fail country?

Hi all, I'm thinking about buying a HP computer (Pavilion P6310de). It comes with Windows 7 and I want to add SuSE to it. Can anyone tell me good or bad things about HP computers? Do they play nice with Linux?

[opensuse] sftp-server problem on OpenSUSE 11?

by Boris Epstein

Hi all, I have a few systems here that are OpenSUSE 11.1 and 11.2 machines. For some reason, while SSH into them works just fine SFTP does not work at all. Looks like the SFTP subsystem in the SSH server (/usr/lib64/ssh/sftp-server) never gets activated properly. Has anybody run into this? How do I fix it? Thanks.

[opensuse] BASH prompt - change prompt on the fly -> shorter -> longer -> shorter

by David C. Rankin

Guys, I keep my prompt set so I always have the time and can simply copy/paste the prompt as an rsync or scp or sftp source/destination. example: 21:43 nirvana:~/dt/e17/themes> So if I need to transfer something to/from any host it is just a simple copy & middle-mouse paste for: rsync -uav nirvana:~/dt/e17/themes . One issue that arises is that prompt length grows quickly as you drill down a directory tree, especially if you are su'ed root: eg: [21:55 alchemy:/usr/share/enlightenment/data/themes] # So a solution was to create a small function in .bashrc and short alias to accomplish what I needed. Since in the path statement, '\w' displays the full path while '\W' will display only the current directory, toggling the path required nothing more than re-exporting the path with the 'w' or 'W' set as needed. The function that worked - (note all case statements are on a single line): SetPrompt() { case $1 in w) export PS1="\[\e[0;37m\]\A\[\e[1;34m\] \[\e[1;34m\]\h:\w> \[\e[0m\]";; W) export PS1="\[\e[0;37m\]\A\[\e[1;34m\] \[\e[1;34m\]\h:\W> \[\e[0m\]";; *) echo -e "\n ${0##*/} [w,W] for 'full' or 'current' directory shown in prompt -- try again.\n" >&2 return 1;; esac return 0 } Then the efficient aliases used for 'SetPrompt w' or 'SetPrompt W': alias spw='SetPrompt w' alias spW='SetPrompt W' If you use different prompts for root and regular users, then just adding a test for the $UID allows you to set the appropriate prompt. (I like my user prompt in blue/gray and my root prompt in red/yellow: SetPrompt() { case $1 in w) [[ $UID -eq 0 ]] && \ export PS1="\[\e[0;37m\]\A \[\e[1;33m\]\h\[\e[0;31m\]:\w\[\e[1;33m\] # \[\e[0m\]" || \ export PS1="\[\e[0;37m\]\A\[\e[1;34m\] \[\e[1;34m\]\h:\w> \[\e[0m\]";; W) [[ $UID -eq 0 ]] && \ export PS1="\[\e[0;37m\]\A \[\e[1;33m\]\h\[\e[0;31m\]:\W\[\e[1;33m\] # \[\e[0m\]" || \ export PS1="\[\e[0;37m\]\A\[\e[1;34m\] \[\e[1;34m\]\h:\W> \[\e[0m\]";; *) echo -e "\n ${0##*/} [w,W] for 'full' or 'current' directory shown in prompt -- try again.\n" >&2 return 1;; esac return 0 } Here is an alternate root prompt that I really like as well: PS1="\[\e[1;34m\][\[\e[1;31m\]\A \[\e[1;34m\]\h\[\e[0;31m\]:\w\[\e[1;34m\]] # \[\e[0m\]" (to try out the prompts, just copy and paste the ( PS1="stuff" ) line to your command line and hit return -- in any terminal) Somewhere in the past I recall suse having some 'beautify path' options that did something similar to this, but I couldn't find it with a limited search. Does anybody else recall something like a 'beautify path' option that would shorten the path to no more than 3 directory depth displayed starting at the current dir and working back up the tree? As long as we are on prompts, here is another super time-saver that takes you back to the prior directory with a short alias that your fingers are already over: alias cdl='cd $OLDPWD' Next time you change directories and need to change back, just 'cdl' Enjoy :p -- David C.
