I have two terminals open and I want to save the current path in a variable and read it from the second terminal that I have open.
Then in the first terminal I type:
Code:
A=$(pwd)
And in the second I type:
Code:
echo $A
that doesn't work though.
I have tried also with
Code:
export A=$(pwd)
and
Code:
alias A=$(pwd)
but nothing seems to work. Is there a way to do this?
I'm trying to read content of file to variable and use this variable in for loop. The problem is, when I have c++ comment style in file - /*. Spaces in line are also interpreted as separated lines.
For example:
Code:
Changing $files to "$files" eliminate these problems but causes that whole content of variable is treated as one string (one execution of loop).
my script has a variable which comes in the form +00.00 +0.00 -00.00 or -0.00 (the numbers can be any in that form) for any that have a + symbol I need to remove the +, but if it has a - symbol it needs to stay.
i need to make a new variable with the string from the old variable btut without any plus sign. I have tried a lot of different ways with no success, each thing I tried either left the + or removed the entire string. I think this should work but doesn't
foo=+12.40
bar=${foo#+}

I am trying to write a script which can read the names of all folders within a given folder into separate variables. In effect, if a folder contains a folder "Folder1", "Folder2", "Folder3", the script would read those names into variables such as:
Variable1 = "Folder1"
Variable2 = "Folder2"
Variable3 = "Folder3"

At my wit's end I can't find anything that I understand well enough to use. This is for a Unix class, we are working with shell scripting. File1 has 5 in it and File2 has 100 in it.The teacher wants us to read the values then do the math. This is what I have so far:#!/bin/bashvar1='cat File1'var2='cat File2'var3=`echo "scale=4; $var1 / $var2" | bc`echo The final result is: $var3
View 9 Replies View Relatedhe clicks on everything on his GNOME desktop, and manages to delete everything, including menus, icons, etc. The people he lives with aren't skilled enough to fix it, and I live a good eight hours away. I have remote capabilities with NX, but that requires them to initiate a connection to my workstation here, which is more painful than I thought it would be. I need a way of locking down the desktop, so it's read-only, so he can't make the changes he seems to keep making. I figure I could make the .gnome directory read-only, but I don't know if that would affect the normal operation.
View 3 Replies View RelatedI want to add a path (/usr/sys) to the global $PATH. I will use this to test commands and scripts, which I don't want to be mixed up with regular commands. I've added the path to /etc/environment. When I start a terminal session under my user account, the path is included in the $PATH variable. However, when I start a root terminal, it is not. Is there a way to to change $PATH on one place where it will also affect the root terminal, or do I have to change it on 2 locations?

View 6 Replies View RelatedI am using CentOS5.5 & everytime it is showing command not found. If I export the path as below it will be working fine until a reboot. Again same error i.e command not found if I open new terminal. Every time I am exporting as below:
#export PATH=/sbin/:$PATH
#export PATH=/usr/sbin/:$PATH
#export PATH=/usr/bin/:$PATH
#export PATH=/bin/:$PATH
How can I set these permanently as that the paths should automatically be exported for everyone user whenever the system boots. And command completion also should happen for eg. #fdi (press tab), then it should show available options such as fdisk, etc.

View 7 Replies View RelatedI'm trying to make an environmental variable RPMS that will resolve to a website. I know I have to make the changes in .bash_profile, but all the things I try don't seem to want to work.
I've tried:
PATH=$RPMS:ftp://rha-server/pub/os/rhel5/Server/
or simply just making the variable itself
$RPMS=ftp://rha-server/pub/os/rhel5/Server/
The second one made a variable just fine, but when I attempted to run this command:

I am trying to strip the .wav file extension from a file name so that I can pass the result to lame encoder. I started to write a BASH script that looks like this:

It doesn't work very well though. For the life of me I can't seem to discover how to use basename in a suitable way for a script like this.

Basically i have a 1TB USB HDD that is formatted HFS+ (i used to use it attached to a hacked AppleTV, it has loads of media on it).
Appletv wasn't great, so now i have a lovely acer revo running XBMC Live, and it's blooming great. my problem is my USB drive mounts, but i think it's read-only, as i am struggling to sftp new files to it. so my question is:
How do i make the drive writeable?
I've read things about disabling journling, an fstab file, chown in terminal, but im really struggling.
In temrinal if i navigate to the /media folder and run ls -al, i get this: (note the usb drive is called AppleTV)

When I try to go to a virtual terminal from X the writing is too dim to read. When I boot to run level 3 all is fine, then I "startx" and use the gui. If I "ctrl-alt-F3" the printing on the screen is so dim that I can't see it. Is there a setting for this somewhere that I haven't found. Before installing Slackware 13-64 I ran Zenwalk for over a year and never had this problem.
