commands added to .bash_profile

Hi all,

I added some alias commands to .bash_profile file for a user (the user shell is bash). I rebooted the system and logged on using that user. Yet, I don't see the aliases I've added in the file configured for that user. Why?

Linux Enterprise 4.5

Try the simple command
alias
and it will print existing aliases. then do
. your_config file
and try again (Notice the 'full stop' at the beginning of that line)

For future reference, you'll never need to reboot for simple things like this.

I know when I do .bash_profile, all the commands in it will be executed. But my question is: why the alias commands in .bash_profile do not run at login?

Code:

[user1@rac2 ~]$ cat .bash_profile
# .bash_profile

# Get the aliases and functions
if [ -f ~/.bashrc ]; then
        . ~/.bashrc
fi

# User specific environment and startup programs
PATH=$PATH:$HOME/bin

export PATH
unset USERNAME

if [ $USER = "user1" ]; then
 if [ $SHELL = "/bin/ksh" ]; then
  ulimit -p 16384
  ulimit -n 65536
 else
  ulimit -u 16384 -n 65536
 fi
 umask 022
fi
..
alias db='cd $ORACLE_HOME/bin'
alias crs='cd $ORA_CRS_HOME/bin'
alias crstat='~/scripts/crstat.sh'

[user1@rac2 ~]$ alias
alias l.='ls -d .* --color=tty'
alias ll='ls -l --color=tty'
alias ls='ls --color=tty'
alias vi='vim'
alias which='alias | /usr/bin/which --tty-only --read-alias --show-dot --show-ti lde'

Hi,

Check if you have a .bashrc in the user's home directory. If you have, then put the aliases in that file instead.

Looking at the bash_profile script that's where it checks for aliases and functions

Code:

# Get the aliases and functions
if [ -f ~/.bashrc ]; then
        . ~/.bashrc
fi

.

Then logout and login again to check if it works.

Kind regards,

Eric

Because .bashrc is only defining them, not running them?
