View 1 Replies View RelatedHow would I clear my commandline history at logon/logoff/startup time? I tried this : editing my /etc/rc.d/rc.local file like this I know this is for system startup
Code:
#!/bin/sh
# /etc/rc.d/rc.local: Local system initialization script.
# Put any local startup commands in here.
Also, if you have anything that needs to be run at shutdown time you can make an /etc/rc.d/rc.local_shutdown script and put those commands in there.
#clear user history ~/.bash_history
echo "" > ~/.bash_history
#clear root history /root/.bash_history
echo "" > /root/.bash_history
But when I reboot, the history still remains.

I found one post on the subject with no reply and have read the bug reports and the problem was not mentioned. I tried to find the file containing the history without success.

I've done a bit of googling, but can't find a clear answer on this. If I format a USB drive using NTFS, so I can store copies of files from my Win 7 machine and my Lucid machine, will it work.

It always comes up with a Requested of "no change". If I do a Request Upgrade it changes to "BREAK (upgrade)", but when I hit Apply Updates, I get the following error:
Could not commit changes - Adept Notifier
There was an error committing changes. Possibly there was a problem downloading some packages or the commit would break packages.
I can live without a new language-pack-en, but I would like to clear it from my Adept Notifier, so I can see when I really do need updates.
Ok, completely fresh install of lucid (64bit) on my asus deluxe msi with dual audio cards, dual hds, dual cpu(3.0 amd2) and a whopping 3.5 ddr2...
Everything works wonderfully, Except:
The old method of making sure windows booted first... Gone with Sarah on that plane.
Is that Lst, 1st, Ist or what on /boot/grub/menu.xxx?
Since this is a clean and good install, should I be worried that it's completely blank when I edit it?
knowing about 32x compatibility software would of been nice.
I've been using empathy to chat on MSN. The problem is I can't erase my password when I want to log off. Theres just one user on this machine, I know it would be easier to create diffrent profiles. But I just want to be able to tell empathy that it should ask my pw to log on to my account.
Is this possible?

I am not clear as why by default ScriptAlias is present in the default vhost is it necessary to keep in other Virtual Hosts. Similarly /doc/ what is this referring to in following section

My mom just switched from Comcast to Clear 4G Mobile Internet service and I don't know how to get this working on a Ubuntu 10.04 system. The Clear installation USB only gives me two options: Windows Users and Mac OS X Users. I was wondering if the Linux WiMax driver would be instrumental in having Clear work on my Ubuntu 10.04 system. From this website: [URL]..
However, if there are no other options, we do have 10 days to back out of the contract.I'm a dim light bulb when it comes to these things. If I didn't provide enough info, just let me know!
Ubuntu 10.4 64-bit.I am almost certainly using the wrong term here, but if I knew for sure what I was looking for I probably would have managed to google it.In a fit of minor insanity, I used ffmpeg to convert all my video files I've impulse downloaded over the last decade or so to mp4, mostly because Easytag will happily tag them an assist in reorganizing them, but of course some videos didn't convert, either properly or at all due to issues with the original file.
But - every 108 -123 (Going by the filecount in my trash when it happens; I've wondered if the actual number is 127 or 128 but haven't gotten that definitive yet.) videos or so, totem dies, and so does every other video player I can use, VLC, mplayer, et al. For awhile I rebooted, then I figured out just logging out/in cleared the error, but I've yet to narrow down what exactly is causing it.Since it crosses all players I can only assume that there is some kind of cache that is getting filled up that is cleared when you logout, but after doing some digging it's nothing cleared by anything I've found like bitbleach.
My system is giving me a low space on filesystem warning. When I run disk analyser, it seems that /var/lib/apt-xapian-index is using 97% of it!! That's 8.9GB. I found another post which explained that each time this package runs it builds a new index set, and how to make it only update new packages. I made that change, but this doesn't release the 8.9GB that I guess can just be cleared down somehow...
I hope it can be cleared down anyway. How to clear all this down? I do want the package to remain running on the system, I just want to clean it up and release all that space. I'm on Lucid, I also saw the warning on Jaunty but it went away after upgrade to Lucid... now it's happening again, I can't ignore and hope it goes away for ever!
could't find anywhere on how to clear all IPs in Darkstat,anyone knows?
View 1 Replies View RelatedI'm an Ubuntu user and I always chat on Yahoo, MSN, Gtalk and Facebook accounts using Empathy (with the fact that there is no better alternative; pidgin is heavy for me). I have noticed long earlier that all the chat histories are saved. However, just today I discovered that I couldn't delete those histories. Hitting the clear option from the right click fly out menu doesn't permanently remove the history. I can see them again when I try to look for previous conversations.
I believe there is a way to permanently remove chat histories from Empathy.
