GloMoSim Installation In Linux Problem

I'm new to linux but I use linux a little at school and by connecting through a shell at home. Anyways, I just installed linux a little while ago and I opened a shell and tried to compile some java code by going to the directory of the code and typing "javac someCode.java" like I do at school but it says the command is not found.

I previously had installed the java runtime environment and I just went to go and try to install the java development kit but it says it was already installed.

Is there some sort of path I need to set for the shell to look for the java compiler? Thanks in advance.

Edit:
I have added aliases to my .cshrc file at school and I just found a bashrc file and csh.cshrc file in the /etc folder. Sorry, I'm really new to all of this. Anyways, I'm geussing I have to edit the bash file? Can anyone point me to a good tutorial of scripting for these files???

I'm sorry to ask such a simple question but every time I think I figure something out or think I'm going somewhere get stopped dead in my tracks. My friend installed linux on my computer and then moved away immediately so I have no one to help me!

I downloaded the webcam program Cheese. I found through some tutorials that I have to copy the folder to the /opt/ folder and the only way to do that is through the terminal. I found this tutorial and still can't manage to copy the folder. These are the problems I run into:

1. I don't know where to open the terminal. I've tried opening it from the extracted Cheese folder in my downloads folder and from the /opt/ folder itself. It opens up but:
2. when I type the command sudo cp -r cheese /opt/ it will ask for modernnewspeak's password. When I try to type this in nothing happens, even though it JUST let me type in the command. I pressed "enter" thinking maybe it was hiding my password and I get the message "cannot stat 'cheese'. No such file or directory"

please tell me what I'm doing wrong! I tried to follow that tutorial and look through the FAQ here but I cannot figure this out. Thank you in advance!

Is there a way to have a script called source, that can be run without the full path?

Ex:
When I run:
export PATH=/home/user:$PATH
source

I get:
Code:

$ source
bash: source: filename argument required
source: usage: source filename [arguments]

However I want it to run my script called source:
Code:

$ cat source 
#!/bin/bash
echo "Hello World"

Is there way to override a shell builtin in the PATH var or some other way?

What I did in windows was create images of my drive and restore them.

in linux I am running

Code:

rsync -aAXv --exclude={"/home/*","/dev/*","/proc/*","/sys/*","/tmp/*","/run/*","/mnt/*","/media/*","/lost+found"} /* /path/to/backup/folder

and this creates a folder for me with all my files, and apparently saves meta data like permissions and paths...

Since I'm using arch and things break sometimes,I'm booted into a CLI with errors and cannot figure my way out since I'm a noob... would I be able to just delete my entire root and replace it with the rsync backup without a problem?

As a newbie, I started with Linux ubuntu 14.04. I try to avoid using terminal commands. FamilyTreeBuilder was not possible.

After upgrading to ubuntu 14.10 I was able to install (with Q4Wine 1.1-r2) MyHeritage FamilyTreeBuilder sw nearly saccesfully. After installation when I try to open program it tries to make a customer data folder. That will give an error message:
Couldnt make folder: C:\user\peter\My Documents\MyHeritage\

FamilyTreeBuilder does not give any possibility to change the path.

I have SSD (sda = C: ) for Linux and separate HDD (sdb = D: ) for my files. For some reason, I am not allowed to write any files to sda (???).

Can anybody help?

books say that PATH variable contains the locations where the shell searches the commands to execute them.

I created a shell script and saved it in /home/user/Downloads directory and then i ran this script from the /home/user/Downloads directory. It did not execute.

however when i did set the path
export PATH=$PATH:/bin/sh within /home/user/Downloads directory, the shell script executed. Does it not mean that PATH variable is holding the locations of the shell program rather than the commands that are to be executed?

everytime i have to give the location of the shell i.e /bin/sh in the PATH variable no matter from where i am executing my script

hi,

Because i am cross compiling busybox for an arm board and can't install directy busybox on it (it don't have apt-get/sudo/make) i tried to compile busybox with arm-linux-gcc and "make" it in a custom directory with /usr/ /bin/ sbin/ this way i could copy paste the folder and the exe in a clean root and transfert this root to my board.

Sadly i don't seems to be able to change the installation patch.
i tried with :
Code:

make install PREFIX=/home/blabla1/blabla2/blabla3

but when going into the blabla3 folder i find no file (/usr/ /bin/ and /sbin/ are present because i created them myself).

./configure can't be used because the file don't exist.

Any idea on how i could change the installation patch ?

Hello everyone Iam new to Linux Iam trying to install java Jdk into my system>but I couldn't set path for it after some time when I have opened the terminal Iam getting this bash: export: `javafx-src.zip/': not a valid identifier

Hi,
I am crosscompiling u-boot for the beaglebone black and I have a problem that I don't understand.

I have installed correctly the linaro cross-compile tools and export the environment variable CC as:
export CC=/path_to_linaro_arm_cross_compiler/bin/arm-linux-gnueabihf-

And if I type in the terminal:
${CC}gcc --version

I see the linaro's compiler version, so all seems to be ok.

But, when I try to create the config file for the BBB with the command:
make ARCH=arm CROSS_COMPILE=${CC} am335x_boneblack_defconfig

It complains with the message: "/bin/sh: 1: cc: not found"

Am I missing something?

I have a user: mim that has within it a folder /mimmim and within that, a folder called
/Src. user: mim has root privileges.

There is an Install file in /home/mim/ that uses a file in /Src called pgp.h. pgp.h references a file /openssl/opensslv.h. The opensslv.h is actually in the newer openssl installations he /usr/local/ssl/include/openssl/

I tried to do a 'sudo ln -s /usr/local/ssl/include/openssl openssl' from /home/mim/, as well as from within the /home/mim/mimmim/ and from within /home/mim/mimmim/Src/. I still get this error however:

pgp.h:16:30: fatal error: openssl/opensslv.h: No such file or directory
compilation terminated.

I guess I am not sim linking correctly.
