I've set up an alias in .bashrc (let's call it alias1), and am trying to set up a sudo NOPASSWD rule for that particular command. So far, I've attempted: user ALL = NOPASSWD: alias1 user ALL=(ALL) NOPASSWD: alias1 But keep getting told I have a syntax error - presumably this is because visudo doesn't recognise alias1? I've already checked that alias1 works correctly, so I assume I'm just referring to it incorrectly.
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.
I successfully edited the .bashrc file to get ruby version manager (rvm) working. Now I would like to turn that setting into an alias so that if i type the word 'ruby' into the terminal it not only goes to the rvm settup but also defaults to my webdev folder which is in my user home directory and also exicutes a command that will open up gedit ready to be used as the text editor for editing the .rb files. Can this be done i would settle for some added code for the 'if then' statement: so far it looks like this:
[Code]...
I don't want to mess with the default setup on this system too much and think things could get out of hand if i am not careful. So am cautious about doing anything at this stage. I wonder if it is possibel thought to setup that whole 'if then' statement as an 'alias'. I read a few referances to alias and looked in the manual like any good newby should but am needing your help please. getting out of the MSwindows mind set and into the linux logic is not so easy but is a great experience
I was wondering whether anyone knows how to add preformatted text to the bashrc file? I'm ashamed to say I did already read this somewhere but had no use for it and as such forgot it! I'm possibly googling the wrong keywords, so apologies if it's an easy answer to find (with the right keywords!).
Just for completeness, the reason I'm doing my bit introducing my partner to linux, and I've 'embedded' a terminal on her desktop, I want to now add a little ASCII animal with a welcome message (I'm ok with getting the welcome message and colors sorted), much like the one seen in Linux Mint.
I am curious since "Run command as a login shell" is UNTICKED (I think for all new users) under Gnome Terminal -> Menu Bar -> Profiles -> Edit -> Title and Command , BUT .bash_profile is sourced. I thought .bashrc should be sourced instead ?
The following line is in the /etc/bashrc file. I was trying to decipher it but no google results explain it in detail.PROMPT_COMMAND='echo -ne 33]0;${USER}${HOSTNAME%%.*}:${PWD/#$HOME/~}07"'I understand that 33 is the ASCII character for ESC but not sure what ]0 does or anything after the HOSTNAME variable.
recently I did some changes to my bashrc file the changes are as follows export JAVA_HOME=/usr/java/jre<version>/bin/ export PATH=$PATH:/usr/java/jre<version>/bin
I have to move our DNS server to our VMware environment. With that comes a new IP address (10.10.102.x). The current address is in the 192.168.10.x. range. Is there a way to bind an alias to my NIC that has a different IP range? I tried it and it didnt work but if i used two IPs in the same subnet range it works. What are my options?
I don't want to go around and modify all my clients to use the new IP. I have many other things running like Nagios and Puppet. Unfortunately this is going to suck and I probably dont have any other options.
Is there anyway you can configure either OpenVPN client or the system to allow connections using OpenVPN to be made to computers on the OpenVPN network using their alias rather than their IP address. This may sound blasphemous but you can in Windows. That is if the VPN network is say 10.x.0.x I could connect to Comp4 or Comp2 using Comp4 or Comp2 not 10.x.0. 4 or 10.x.0.2 or whatever IP is allocated by the OpenVPN server. If the OpenVPN server has not been restarted then it will usually allocate the same IP every time the same client connects.
Can anybody explain how I can set a hostname alias in RHEL5. We are testing RHEL to replace our Solaris LDAP servers, one of the things we need is to be able to set a hostname alias on the public interface.In solaris we can just update the /etc/hosts file to something like
ipaddress hostname alias1 alias2 Things looks alittle different in RHEL, the host file only contains 127.0.0.1 hostname.fqdn localhost.localdomain localhost
I read about the sysconfig/network files but can only see about changing the hostname there and nothing about setting a different alias.
I have searched the forum high and low for the solution with no success, so I will now post this problem, with all known facts. Linux (and Fedora) is brand new to me so I'm somewhat illiterate with the language and recommendations from reading other threads. Please bare with me. I'm reading the book Beginning PHP and MySQL from Novice to Professional by Cristian Darie.The book has you create an Alias directory for creating the tshirtshop web-based application.
The book uses the directory /home/username/tshirtshop. However, I did not want this in the /home directory, so I created a new directory from the root directory /workspace/tshirtshop. Below are the areas of interest in the file httpd.conf (I restarted the httpd service each time I edited this file):
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.
This should be a simple thing to accomplish, but I can seem to figure it out. Essentially, I want to have a bash alias or function that will let me recursively grep the current directory. A while back I added this to my .bashrc:
Code:
alias rg="grep -r --exclude=*/.svn/* --exclude=*.swp"
This works fine, (and also ignores any svn and vim swp files), and I can call it like:
Code:
rg foo *
However, 99.999% of the time, I am only interested in searching in the current directory, so the "*" is a bit redundant. Also, I would say 5-10% of the time, I am typing faster than thinking and forget the "*", so grep just sits there trying to read from stdin. It's a pretty minor thing, but ideally I'd like to be able to just type:
Code:
rg foo
I've tried creating a function to handle this:
Code:
function rg(){ grep -r --exclude=*/.svn/* --exclude=*.swp $1 * }
but it behaves exactly the same as the alias above. escaping the "*" with 's doesn't work, and neither does trying `pwd` (or even a hard-coded path) in its place.
I am trying to configure virtual alias using regular expression.
For example :
Email send to user.1@example.com and user.2@example.com will deliver to user mailbox.
Email send to user2.1@example.com and user2.2@example.com will deliver to user2 mailbox.
And the numbers or alphabet in between user name and the domain will be vary , I can't just do a normal alias.
I been try to play around with main.cf and the virtual alias table but still not able to get work. So I am not sure is the main.cf didnt configure correctly or the regular expression is not working.
I'm not sure if this is a Debian-specific question or a KDE question.

Question: Upon logging in (typically, for the first time each day) I would like to see a console window/shell or a simple terminal-emulator/shell automatically open up.
The reason is: In order to get my .bashrc to execute I have to log-in, then bring up an xterm or some other terminal-emulator.
Background: My .bashrc has a once-per-day routine/section that will set up my desktop to look the way I want it on my initial log-in (primarily with my Java applications up/running and displayed and waiting for me).
Then, later on that day whenever I bring up new bash shells, my .bashrc is executed but that once-per-day routine/section is no longer executed.
I am using Ubuntu 9.10. I was installing network simulator 2. After installation I get the following message.
Please put /home/administrator/Downloads/ns-allinone-2.34/bin:/home/administrator/Downloads/ns-allinone-2.34/tcl8.4.18/unix:/home/administrator/Downloads/ns-allinone-2.34/tk8.4.18/unix into your PATH environment; so that you'll be able to run itm/tclsh/wish/xgraph.

My friend suggested that it is something to do with .bashrc file. I fund files like .bash.bashrc.
I tried to make a function to put in either my .bash_aliases or .bashrc file to make a local backup of a file, but when I call the function and try to use tab completion I get the following error:
Code: cp: cannot stat `help': No such file or directory The function I added is as follows: Code: function bk
[Code]...
Also interestingly, if I define this function at the prompt rather than in my .bashrc, tab completion works fine.
how to edit or add codes to ~/.bashrc?? and also what is this bashrc if anyone could explain... i have tried editing this bashrc without success... how to save the changes in bashrc...
