Programming :: Where Are BASH Commands Stored
Feb 21, 2011Where are the other BASH commands/exe stored? If the commands are part of the exe of BASH than ls would not be in a path, correct?

Ubuntu :: BASH Quote - Calling Commands Stored In A Variable?
Feb 19, 2010I am having some weird problems with calling commands stored in a variable (I need to do this to assemble a command with a bunch of parameters automatically and then execute it).Example code that will replicate the weirdness:
$ echo "hello world" > "test file.txt"
$ cat "test file.txt"
hello world
[code]....
I would expect the output to be:
hello world
What happens to the quotes? I have tried various combinations of single quotes, escaped quotes, etc, but it seems like quotes in a variable are not evaluated as quotes when that variable is executed.

I am trying to take an input file of ip addresses and corresponding netmasks and put it into a format to be loaded onto a juniper switch. the result should look something like this.. x.x.x.x/netmask using the cidr notation. no matter what subnet is provided though, /32 always gets appended to the end of the ip even when it should be /16, /24, etc... also, the cisco part works fine so that doesnt need any attention.
Programming :: Combining Commands And Var's In Bash Shell Script?
Jan 5, 2011I have a command which on the command line needs to look like this
rlam -if3 '!pvalue -H image1.jpg' > image2.jpg
Nevermind what rlam or pvalue do ... they are part of a program package I am using. The above command works on the command line, and also when written verbatim in a bash shell script.
My problem is: in the script I wish to replace image1.jpg with the content of a variable, e.g.
IM1=image1.jpg
How to I get the script to insert the value of $IM into the command when the pvalue part of it needs to be quoted?

Programming :: Simple Bash Script Is Not Running All Of The Commands?
Jun 14, 2010I am running a simple script that I copied from slug.ceca.utc.edu/docs/2009-3-26-linux-server-health.pdf and edited with the names and paths of my own servers. I don't know much about scripting (re: nothing) but I wanted to try and be efficient in my new role as a Linux Sys Admin. The script was saved to root's home directory and runs as part of root's crontab once a week. The script runs with no problem, but it doesn't actually seem to run all of the commands contained within. It skips some in the middle and the end and I don't know why. The script itself is this:
Code:
#!/in/bash
uname -a > /tmp/server.txt

Ubuntu :: Where Are Bash Profiles And Gnome Panels Stored
Jan 5, 2010I have a bash profile (with custom terminal color settings) and also a gnome panel (with quick-launchers on it and other customizations). Assuming these things are stored in text files, where in my ~home directory can I find them? I ask because I want to duplicate them on a another linux box to have the same bash profile/taskbar, and If I can do it by copying files instead of manually recreating them, it would be better.

General :: SSH Connection From BASH Script Stops Further BASH Script Commands
Dec 3, 2010What happens when the script executes is that the ssh connection works and parks me at the remote hosts's shell login. Therefore, the "firefox" command refuses to execute. I need to know how to make the "ssh" connection occur, stay open, and go into the background so that the rest of the script can execute.If I could also do this with the "firefox" line so that the entire term window could be closed would also be helpful.

Oct 20, 2010I have machine that I used to VNC to on my network with Remote Desktop Viewer from my Fedora 12. When I first connected I checked the checkbox that I wanted to store the pw. Now the pw on the other machine has changed but Remote Desktop Viewer does not ask for a new password, it just gives me a black screen, like I am connected but I can't see anything. I'd like to know if anyone knows where this pw data is stored on the system so I can start fresh. I already tried uninstalling Remote Desktop Viewer and installing it again.

Jan 12, 2009I need to call a function that takes a string array as argument, declared like this:Code:int someFunction(/* some parameters... */, const char* s[]);I'd like to know how to allocate memory for the string array. I know a string is an array of chars and an array is a pointer to the first element, then a string array should simply be a two dimensional char array. But is it a single memory block where all strings are stored consecutively?? Or is it a base vector where each element is a pointer to a separate memory block that contains a single string?More specifically: should I malloc() a single memory block large enough for all the strings? or should I allocate separate blocks for each string plus an extra one for the base vector?

Sep 10, 2010This is a really odd bug I can't seem to figure it out. Basically, commands like ls can see all the files in the current directory, however when I go to execute the file it will give errors like "file not found", even when it most obviously is. If you look at my command history in the screenshot, you can see I can ls into a directory and see it's contents. When I try to run the file, I get the "no such file or directory" error.
However, if I type simply 'vm', I can't use tab completion to complete the directory name, and my third command is me typing 'vm' and hitting tabtab, it lists a bunch of vmware specific tools instead of the subdirectory name. I can then ls and see my current directory contents, and it will list only the single subdirectory. However, then I tried to use the full filepath from root to run the file, still to no avail. If anyone has any insight,
General :: Bash - Passing Commands To CLI Using A Script
Jul 31, 2011is there any way I can pass commands to the CLI of a tool directly?
I would like to script some actions, for example:

I do not need to retrieve the results (I watch it in the log file). how I could realize that? There is now way to do this using command line parameters, at least not that I found out. So it looks like I have to figure out sth myself. Maybe I could automate screen in a way to detect the prompt and "paste" my command there. Are there tools for this on Linux?
