bash command not found
 

Hey there
Is anyone familiar with the following? :

-bash: id: command not found
-bash: dircolors: command not found
-bash: biff: command not found
-bash: dircolors: command not found
-bash: id: command not found
BT ~ $

This happens whenever i start the terminal window.
I was having a problem with my javac and java and I made some changes to profile and .bash_profile files. The fact is that finally i fixed java and javac but now i got this problem.

Many thanks for your time and for sharing your knowledge

Could you post your .bash_profile and .bashrc

Chances are you removed the /bin and/or /usr/bin directories from your $PATH. These directories are where many Linux system executables are stored so they need to be in your $PATH or you'll see results like what you posted.

Or maybe the executables are executed before PATH has been properly set-up (somewhere in profile).

# /etc/profile: This file contains system-wide defaults used by
# all Bourne (and related) shells.

export MANPATH=/usr/local/man:/usr/man:/usr/X11R6/man
export HOSTNAME="`cat /etc/HOSTNAME`"
export LESSOPEN="|lesspipe.sh %s"
export LESS="-M"

# If the user doesn't have a .inputrc, use the one in /etc.
if [ ! -r "$HOME/.inputrc" ]; then
export INPUTRC=/etc/inputrc
fi

# For root users, ensure that /usr/local/sbin, /usr/sbin, and /sbin are in
# the $PATH. Some means of connection don't add these by default (sshd comes
# to mind).
if [ "`id -u`" = "0" ]; then
echo $PATH | grep /usr/local/sbin 1> /dev/null 2> /dev/null
if [ ! $? = 0 ]; then
PATH=/usr/local/sbin:/usr/sbin:/sbin:$PATH

What i post before was the .bash_profile file.I cannot find .bashrc Well i think that i have made a big mistake.When i rebooted my pc i could not use the startx not even su and i decided to reinstall BackTrack(My linux) and to create a new user
The fact now is that javac again is not recognized
Please can you explain how exactly should these files be(.bash_profile && .bashrc)
What can i do now that i have lost .bashrc?

Many thanks for dedicating your time

It's generally best not to modify /etc/profile but to make your own .bash_profile and .bashrc which will keep you from screwing up the global environment. I noticed inthe above scripts you had used commands like id before you had added the standard /bin and /usr/bin directories to the $PATH.

Here's what I would do if I were you.

1) Create a .bash_profile script in your home directory with the following content:

Also create a .bashrc file in your home directory with the following:

Assuming javac lives in /usr/local/jdk1.6.0/bin you will now be able to use it and the rest of the $PATH is kept intact (we just tacked the directory containing the java executables on at the end).

This seems to be the glaringly offending line for your original problem (line 17 of .bash_profile). It wipes out the path, and replaces it with /usr/local/jdk1.6.0/bin, and thereafter, the shell interpreter cannot find id, dircolors, or biff.

Hey again

I just want to ask smth to be sure. When you say in your home directory you probably mean(setting the case that i am the user 'newbie') /home/newbie/
Is that right? If that is right i have to say that a .bashrc already exists in there.
Do i have to erase everything in that file and only put the export statement that you gave me or just to put the export statement where the others are?
I did what you said and again javac cannot be found.
You said before that it is not good to modify the etc/profile
Unfortunately for me i made some changes to that files and i am quite afraid that i dont remember which changes i have to take back. Any ideas what i can do?

Please any advice will be grateful

not desirable 'which java'
 

Hey there
I made javac being recognized but now i have another problem.
When i try to run a java file after compilation i get an error that indicates that the versions of javac and java are not the same

which java outputs:
/usr/lib/java/bin/java

now in my case i believe which javac should output:
/usr/local/jdk1.6.0/bin/java

Any ideas?

Dont know how to thank u for your precious help.
Manolakis

BT ~ $ which -a java
/usr/lib/java/bin/java
/usr/local/jdk1.6.0/bin/java

I just noticed that which java with option -a outputs the above
I thougth that this could be useful

Thanks again

Hello, instead of:
try

Yeap
Finally it works.
Honestly i dont know how to thank u. :) :) :) :) :) :)
It was really nice of you.
Can i ask the last question?
What kind of programming language is that?
I mean the code in the profile & bashrc ,etc.
