Slackware bash profile

ibwew · 09-12-2009, 09:13 PM

I need to add some environment variables to my bash profile for an online programming course I've subscribed to. I've been looking for hours trying to find the file I need to edit. Can someone tell me the full path to the file I need to edit. For example

vi ./which/file/do/I/edit

It's a hidden file from what I've been able to find out.

Thanks

.profile in your home directory.

Thanks for the quick response.

That file doesn't exist on my system. If I

vi /home/ibwew/.profile

it opens a new, empty file. I need to add to an existing file.

That is fine, just create a new one.

ibwew · 09-12-2009, 09:56 PM

OK....will do!

I was looking for an existing file. One which had all my Bash paramaters such as my PATH...etc

You can also look at /etc/profile.

OK....maybe I will later but this works!!
I created the file to read "echo hello ibwew" and I see that now when I log in...so I can put my new environment variables there and it should work.

Many thanks for all the help!!!

Hi together,

I'd not recommend to insert such environment-variables in /etc/profile because the /etc/profile is only for settings which belong to all users of the system.

bash when it starts reads at first the /etc/profile and then, if existing the .profile in the home-directory. You may write the settings you'll need into an empty file named .profile and bash will read it when it starts.

Be aware, that you'll have to distinguish if bash starts as a login-shell or not. If not so, bash reads the .bashrc in your home-directory. Be sure to create also a .bashrc if necessary.

See the GNU Bash Reference Manual's section on Bash Startup Files

Hi,

You could setup a .bashrc & .bash_profile for your user or yourself;

Code:

sample .bash_profile;

~$ cat .bash_profile
# .bash_profile
#08-30-06 12:21
#
# Source .bashrc
if [ -f ~/.bashrc ]; then
        . ~/.bashrc
fi

Code:

sample .bashrc;
:~$ cat .bashrc

#.bashrc
#08-30-06 12:20 

# Add bin to path

export PATH="$PATH:/sbin:/usr/sbin:$HOME/bin"

#export PATH="$PATH:$HOME/bin"

# Dynamic resizing
shopt -s checkwinsize

# Custom prompt
#PS1='\[\033[01;32m\]\u@\h\[\033[00m\]:\[\033[01;34m\]\w\[\033[00m\]\$ '

#08-29-06 11:40

if [ `id -un` = root ]; then
   PS1='\[\033[1;31m\]\h:\w\$\[\033[0m\] '
 else
   PS1='\[\033[1;32m\]\h:\w\$\[\033[0m\] '
fi

#
# Add color
eval `dircolors -b`

# User defined aliases
alias cls='clear'
alias clls='clear; ls'
alias ll='ls -l'
alias lsa='ls -A'
alias lsg='ls | grep'
alias lsp='ls -1 /var/log/packages/ > package-list'
alias na='nano'
alias web='links -g -download-dir ~/ www.google.com'

#08-29-06 11:50

#To clean up and cover your tracks once you log off
#Depending on your version of BASH, you might have to use
# the other form of this command
   trap "rm -f ~$LOGNAME/.bash_history" 0

#The older KSH-style form
#   trap 0 rm -f ~$LOGNAME/.bash_history

The .bashrc is very useful! I like to setup conditional within the '.bashrc' to define user or root but use the 'bash_profile to insure that '.bashrc' is present.
