General :: Script After Putting The File In Bashrc?
Oct 23, 2010
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
count=20
while [ $count -gt 0 ];do
sleep 1
echo Press ESC to break the operation
((count=count-1))
[Code]...

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 want to assign the path of a sourced sub.bashrc file to an environment variable. E.g. if I type (or execute) from a known relative location
$ source ../../someDir/sub.bashrc
the sub.bashrc should set a variable like
export MyOwnLocation=/home/user1/unknownlocation/someDir
The problem is I can't use $0 as reference because the script is only sourced not executed. I also don't want to hardcode the path because the location might change and there will be more copies. Is there an easy way to create this information from within the the sourced bashrc file? I use Gnu bash 2.05b on Suse Linux 9.

I got myself a .bashrc file off the net. I checked it beforehand, didn't detect anything bad about it. One thing that's odd about it, is that several spaces are added to the terminal command line.Screenshot:Those spaces are not put there by me. The file can be found here: [URL]..

My friend suggested that it is something to do with .bashrc file. I fund files like .bash.bashrc.

When I add some path in .bashrc by commenting out old path and adding new one like this:
#EXPORT HOME_PLAY=/home/gem/old_play
EXPORT HOME_PLAY=/home/gem/play
EXPORT PATH=$PATH:HOME_PLAY
After saving above changes, I enter the command: source ~/.bashrc Now if I do echo $PATH, the path shows both the old PLAY_HOME and new PLAY_HOME. This is really bad and messes up a lot of things in my project. This problem only goes away if I logout or reboot, a rather very long process. What is happening is that the old path is added to new path element and the old path includes the old path element you want to remove.

Here is a way to prepare a USB flash drive to save your kickstart file to it, and then read the kickstart file from the USB drive during a new Fedora installation.A USB flash drive is recognised by the Linux kernel as just another hard drive.This is how I set up my USB flash drive to use it to store my kickstart file on.You will need a working Linux system to set up the USB drive.

Running 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
[code]....
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'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.

how come I can create a shell script file with two functions, I can execute the file, but when running declare -f, the functions are not on memory, and when invoking the function bash returns invalid. In the other hand, I can copy & paste the two functions at the end of my /etc/bashrc file.... then I can called the function by name.... and the commands within that function run on my session. here is a print of all my bash packets:
[Code]....
Does Fedora has restrictions on shell scripting? I haven't touch bash in seven years, so if things have change on it I'm behind on it, and sorry for my ignorance.

I am currently trying to install Sabayon linux, and it expects to use Grub1 for booting from usb (what am I trying to do). So I copied grub files into boot section, but now I need to "root and setup" it - and that's what I can't do, because I don't use Grub1 normally, since I am on Ubuntu which uses Grub2.
(I decided to use Grub1 instead of Grub2 because Sabayon could have some special params, and I am not that much experienced to copy them in new format to grub2 configuration file). So my question is - is there a way to copy grub1 to MBR without having it installed? (using some utility or something like that).

I'd like a function in my .bashrc file that would allow me to pass text to it and echo the text to a specified file. I know it's simple as "echo 'text' >> file," but ideally, I would want to alias the function so I execute something like:
Code:
user~ $ write 'this is a test' with "write" being the function, and 'this is a test' being echoed to the file. I hope I explained that well enough.

A cluster with a head node and compute nodes. An application with a couple of env variables (App_HOME, PATH) set in .profile (default shell sh). If I login to the head node/compute nodes on a terminal everything works fine. The correct env variables are set and the application works. However, when my application tries to do it, say ssh <compute node1> <application>, it appears the environment variables are not available. It only looks in the minimal /bin, /usr/bin type PATH. This tells that the .profile is not being read
