I tried to set up an alias for update, upgrade and clean by putting this line into my .bach.rc file
Code:
#alias ud= 'aptitude update && sudo aptitude upgrade && sudo aptitude dist-upgrade && sudo aptitude autoclean' but when I type ud I get this error message, by the way I tried the bash.rc entry both commented and uncommented with the same result.

I have two txt files containing x and y coordinates: xcoord.txt & ycoord.txt. I need to open them; read them line by line to get each coordinate; then each time I need to update Xs and Ys parameters inside another file called "dc.in" with the grabbed values.
Finally each time I need to run two exe files ( dc_2002 and st_vac) and produce corresponding output for each Xs and Ys ( dc.in is an input file for this exe files)
I have written the following code but it does not work:
I have a few alias' in my .bashrc to save some typing, mostly ls type variants.
I wanted to add the following:

But it doesn't work anything like the way it does on the command line
When I use the alias I get the following:

how do you download an update or an upgrade (or whatever it's called) on a command line. for chromium internet browser. opened the computer and couldn't watch videos. i tried all the downloads available on adobe's website and all of them are on my "downloads" folder and when i click on any i just get stuff i don't understand and i simply find it easier to download through terminal.

The config file got updated though. I am just worried that this may be something bad.I update the files using the command sudo gedit <config_file>. I haven't encountered this before in Karmic. Has anyone encountered the same error messages? This might be a problem with gedit. I tried doing the following and the error messages also came up:

3. Terminal will show the following:

Running artha from the terminal also causes the error.I've managed to get the top-most line of the error:
error: line 15: bad flag alias index: 0
error: line 15: bad flag vector alias
The hardest thing about this is I have no idea what's causing it. I thought it was gedit but running artha (from the terminal) also causes the error.Sigh. This is a clean install of Lucid, which again makes it even harder to know what causes it.
On two Centos5 servers, yum gives a segmentation fault error when trying 'yum update' or 'yum check-update' after running 'yum clean' :

The error is the same for the other computer except while attempting to update the rpmforge repository. Nothing has really changed on the servers in some time and 'yum update' worked fine on each yesterday and I have no idea why they would both suddenly fail!

I have a Tomato router and it has the capability to have its logs go to a external server. syslog is the obvious choice for this. So I enabled remote logging on my linux server's syslogd (syslogd -r) and I can see all of the logs in /var/log/syslog. What I want to do is take everything that comes from the IP of my router (10.0.0.1) and divert it to its own file like /var/log/tomato to avoid polluting my syslog with external logs.
I can't find any examples of someone doing this. My only solution is to get a script together that strips out any line in /var/log/syslog with 10.0.0.1 in it and puts the line into /var/log/tomato and have the script run as a cron job, but that seems unnecessarily messy.
Unless someone knows that there is a solution, I'm 95% sure that syslog doesn't support this after reading more in-depth of the man page. So I need to migrate to syslog-ng or make a crazy script that runs with cron.
Years ago on AIX I used to create a file of key strokes, including function keys (mainly F3 and F12) into a file, and used that file as input to an INFORMIX program, to automated tasks, something like this:
fglgo myprogram.fgo <keystrokefile.txt
Now, I'm using Aubit language on GNU/Linux, and I'd like to do the same kind of thing, but I can't recall how I worked out the chars for the function keys, I'm using a different emulation (xterm), and I can't work out what characters to put in the key stroke file. My $TERM variable contains "xterm". If I type "infocmp", I get this:
Code:
# Reconstructed via infocmp from file: /usr/share/terminfo/x/xterm
xterm|xterm terminal emulator (X Window System),
am, bce, km, mc5i, mir, msgr, npc, xenl,
colors#8, cols#80, it#8, lines#24, pairs#64,
acsc=``aaffggiijjkkllmmnnooppqqrrssttuuvvwwxxyyzz{{||}}~~,
[Code]....
1. Is the above infocmp output the place I should get the information I need?
2. What chars do I need to put into my file to simulate me pressing F3 and F12?
3. Is there a way for me to put such chars in a file by just pressing those function keys (I tried a here document, but that doesn't work (it's as if the function keys are not even pressed)).
I have a problem with my script. The problem is the system keeps rebooting after I put the directory file in .bashrc. The intentional for putting the file in .bashrc is to run the script automatically after login as root, I don know why is this happen. It was working fine for the first time without putting the file in bashrc. I could break the loop after hitting the "ESC" key. would it be the script problems?
Here is my script

View 2 Replies View RelatedRunning Red Hat (not sure of the build atm) and I need to be able to put all of the IP blocking in a separate file. It will eventually be uploaded to a large number of hosting accounts, and modified from time to time...so it isn't feasible to modify that many httpd.conf files each time we need to add an IP to be blocked. In httpd.conf I can add the "Deny from" line to the following directive and blocks it just fine:
Code:
<Directory "/var/www/html">
#
# Possible values for the Options directive are "None", "All",
# or any combination of:
# Indexes Includes FollowSymLinks SymLinksifOwnerMatch ExecCGI MultiViews

There is an include to pick up all *conf files in ../conf.d, and everything else in there is working just fine. I created a file called robots.conf; it currently has a set of mod_rewrite rules which work. So I added this to that file:
Code:
<Directory "/var/www/html">
Order allow,deny
Allow from all
Deny from 123.456.789.098
</Directory>
It is not blocking access from the IP with it in there.I've done all of the usual things; restarted Apache, cleared browser cache etc. I can also block it using that same directive in a local .htaccess.
I know this is a relatively simple problem but no matter what combination I try for my alias, I don't seem to be able to get it right! All I want to do is scp a file from my current folder to a location on the network:
Code:
scp filename username@computername:/folder1/folder2
This is the usual layout of the command that I use, so I thought that to save time, I would create an alias or even a function which did this for me, so all I had to type was
Code:
scp101 filename
and it would copy it to the set folder on the remote computer...
My attempt at an alias looks like:
Code:
alias scp101='scp !* username@computername:/folder1/folder2'
and I have also attempted a function:
Code:
scp101()
{
scp "$1" username@computername:/folder1/folder2
}
The alias tells me that filename is not a directory, which I assume means that I have some of the syntax wrong in the alias but I did a google search and I can't seem to find a decent example of what I'm trying to do. When I load up a terminal, I get an error message about the "(" of the scp101 function - so I've obviously can't get the syntax of that right either...
I want to access a file, and check the length of every line.After, i want to check and replace all lines with length over 10 characters, with a message.Does anyone have a clue on that?
View 1 Replies View RelatedI have 10.10 Desktop right now.. and was considering the 11.04 beta 2 upgrade. However, when 11.04 comes out.. first.. will I be able to update to 11.04 final from 11.04 beta (if so is that automatic.. or do I need to do clean install)? Second, will the 11.04 beta 2 upgrade.. as well as the 11.04 final release.. remove/replace old 10.10 stuff.. or is an upgrade going to leave a lot of stuff around and thus a clean install is the best way to go?
I have a lot of stuff.. bookmarks, tools, data, etc on my linux box.. and while I do have a 2nd drive that I can move stuff to, if the upgrade path is as clean (or almost as clean) as a clean install, I am fine with that. I recall from Windows upgrades, there is generally a lot of remnants left behind that can slow things down or just sit around taking up space for no good reason. So I want to avoid anything like that if possible.
I'm working on a custom Ubuntu 10.04 live cd, and I've found updating the Plymouth splash uses up a lot more disk space. The culprit seems to be the command update-initramfs -u, which is needed to apply the new splash image. I'm guessing it's making a new intrd image or something.
View 3 Replies View RelatedI'm looking for a way to make a bootable floppy that has drdflash.img, my flash utility and my bios file on it for a bios recovery disk. This is on a board that has a failed bios, so everything is pretty much dead (except for the humble floppy drive). I don't have a screen to work with so this floppy needs to be able to run the utility and automatically flash the chip for me. I've heard this is possible, but am unable to find clear instructions on how to do any of this. I know the basics of it is to copy the bios file and flash utility to a floppy along with a bootdisk that will run these things (sometimes the .bat file needs to be modified in order to do this automatically). So I've downloaded drdflash but it came as a .img and I don't think it can be 'just' copied to disk. I came across the 'dd' command but have also heard its nicknamed 'data destroyer' or words to that effect.

View 9 Replies View RelatedI have a compaq nx7010. It started out with 8.04 or perhaps 8.10. I upgraded it through to 9.04 when that became available. I have not upgraded to 9.10 year, because I recall it took me a fair amount of time to get my system working correctly after the 9.04 upgrade. At a guess, audio went down, wifi broke, and that sort of thing. I am now finding that apps I use are not releasing new versions compatible with 9.04. And I see 10.04 is on its way, and I understand it is best to go from one upgrade to the next rather than jump a release.
Here's my question:
I get the impression it is cleaner and more stable to do a clean install as opposed to an upgrade. I've also seen many people expressing that view. I've always just gone with upgrading because I didn't like the thought of having to set my whole computer up the way I like it, again. Is there a way to do a clean install that will keep my system the way I like it? For instance, to not have to reconfigure every application?
I have my partitions set up like this:
ext3 /home
ext3 /
linuxswap
Just how much config related stuff is stored in the /home folder? Or is this purely user files? What is the consensus? Is it better to upgrade or to do a clean install? My intention is to have a stable system that does not require hours of my time to get sound and wifi working, with the latest release on it (so that I can run the latest apps).
I have tried to do a clean install of 10.10 on a system that previously had 9.4 on it. Did not do an upgrade just requested a clean install of UBUNTU. Install proceeds to create user name/password page then just stops. Install line below says ready when you are but I do not get a forward to come up on the screen, it just sits there. I have used different hard drives and a different cdrom drive and 2 different installation disks and it does the same thing.

View 11 Replies View Related1. I want to revert back to Ubuntu (I currently am running Dual Slackware/Vista). However, given that at the end of this month 10.4 will be out, is there much advantage to installing 9.10 now and upgrading later?
2. Another way to ask this might be: Suppose you already had 9.10 (which many of you do), and suppose you also have a safe /home (so that in a fresh install you wont loose /home), what is the advantage of a fresh install as compared to Upgrade.
I currently run 9.10 and have / and /home mounted on different partitions. From what I understand, I can do a fresh install of 10.04 on / while preserving my settings on /home. What about the development tools? I currently have Apache web server, Tomcat, MySQL, PostgreSQL installed. I presume I will have to reinstall them if I do a fresh install right? So if I want to preserve these dev tools as they are I should only do an upgrade from the update manager? Are there any major advantages to a clean install over an upgrade?
View 1 Replies View RelatedI used to use Ubuntu 9.10 for a year. I had my home path on different partition (19Gb) than the system partition (12Gb). Before I upgraded, the free space on Home partition (19Gb) was 6.3Gb. I knew that the direct upgrade is not good, so, I format the system partition (12Gb). Then, I install clean version of Ubuntu 10.04 on it. every thing is great. except that, I can not find my files in the old home path. In same time, Ubuntu is telling me that the Home partition (19Gb) (which I have not touch at all) has free space of 6.3Gb and used space of 11.3Gb. It means it can recognize that there is something but it can not open it at all.
