Fedora :: Add Path In .bashrc By Commenting Out Old Path And Adding New One - Command Source ~/bashrc
Jun 14, 2011
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.

I have what I hope is a fairly simple question to answer. In my ~/.bashrc file I can create this alias:
Code:
alias uChmodDP='chmod -R $1 $2' #specify permissions. and the variables work fine. But I cannot seem to get any love from this alias:
Code:
alias umnt='umount /dev/$1' I realize the likely problem is the variable following hot on the heels of a specific directory, but is there anyway to specify a variable in an alias like this? For some reason I cannot umount usb pen drives by right clicking, and have to always resort to the terminal to do so, which for me is no real biggie, but if I could create this alias it would be an even better no biggie to umount using the terminal.
Actually, the inability to right click to umount usb devices seems to be a Thunar issue since I run xubuntu. Using Nautilus I am able to right click and eject/safely remove devices. Using Thunar however, right click unmount always pukes back an error that the device must have been mounted on the command line or some such BS. But like I said it is no real biggie to use terminal, but an alias would be even nicer. I prefer using Thunar and Xubu most of the time b/c my laptop is quite underpowered.

I,m having a rough time getting the terminal environment to recognize my android debug bridge path (which is set in a separate hdd) I used to paste this in my bashrc, but then found that it would make the env system bonkers whenever i attempted sudoing with an option:
# Android Debug Bridge (ADB) sdk path
alias sudo='sudo env PATH=$PATH'
export PATH=${PATH}:/media/Disk/Linux/Android/sdk/platform-tools/
The "alias" line was the one making me have a rough time with env.
Now that i got rid of it everything is well but adb's path isn't exported anymore.

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 was installing a software in my Ubuntu 9.10 and after installation completed it prompted the following warning:
Warning: Your PATH does not point to your newly installed /home/pc/Reflex/software/bin/esorex.
To ensure execution of the newly installed software you should modify your PATH.
Note that "esorex" is the executable file and by typing its name in the Terminal the program starts.
What should I write in my "bashrc" as PATH to that program?

I have a script that I run using ./dom example.com.
I want to add an alias to .bashrc so that I can run it using "d example.com".
I have tried adding each of the lines below in turn but I still receive the error:
-bash: d: command not found
alias d="/bin/bash /home/user/dom"
alias d="./home/user/dom"
alias d="sh /home/user/dom"

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.

Is there a command to know " From where a specific RPM package was downloaded & installed ( The full HTTP/FTP path ) " ? For example, if I had previously installed Firefox from here [URL] is there a specific rpm query, or any other place, from where I can get the full ftp path back.

I found this script [URL].. Basically this is a shortcut for cd-ing my file system..
I can type "save nm" where "nm" is any short name for the directory, like "blog" or "blg" Then whenever I want to go to nm I'll just use 'cd nm'
But it is not working out for me, I get this error every time I enter save:
bash: save: command not found
bash: parse_git_branch: command not found
So How can I make this command work?

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.

I use this command:
Code:
find ./ -atime +360
to figure out the files that haven't been accessed since 360 days. The command above will return results like this:
Code:
/uploads/2010/02/some-file-name.ext
/uploads/2009/08/another-file-name.ext
... etc
I'm taking here about tins of directories, thousands of files. I'm looking to find a command that makes me able to move the results above to another path, and to create that path once it doesn't exist like below:
Code:
mv /uploads/2010/02/some-file-name.ext /old-files/uploads/2010/02/some-file-name.ext
But I want the executed command to create this path
Code:
/old-files/uploads/2010/02/
If it doesn't exist.

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.

I have a program that takes a relative path as input appends it to a some path string to get the actual path.
Now all I can input is the relative path. So if I want to go one level above my input will be ../mypath.
If I know the depth of the path used internally, I can use .. as many times to go to the root directory and then give the absolute path. But suppose I do not know the depth of the directory, can I construct a relative path string such that it considers it as a relative path. One way could be to have enough .. in the path string so that I can force an absolute path for some maximum depth of path.
Is there some path string syntax that I am not aware of but can achieve this?

running Windows 7 64bit with VMware Workstation 7.01-build 227600. I have some knowledge of Linux, I have installed f12 and have updated the system as of 03/22/2010. All updates completed successfully.
1) How do I install VMTools on the f12 (after mounting the CD/DVD tool package)
2) How do I update the gcc files it says are dependencies?
Here's what I get on installation:Before you can compile modules, you need to have the following installed...
make
gcc
kernel headers of the running kernel
and then I am prompted for this input from the install script:
Searching for GCC...
The path "" is not valid path to the gcc binary.
Would you like to change it? [yes]
and this is where I get stuck. How do I get around this or satisfy the requirements for the install?
