Software:Bash:Overriding default aliases

[jerbear]

I have RH8 and have been trying to set up a few aliases. Spefically, my .bashrc file currently reads:

# .bashrc

# User specific aliases and functions
alias la='ls -aF --color'
alias ls='ls -F --color'
alias ll='ls -alF --color'

# Source global definitions
if [ -f /etc/bashrc ]; then
. /etc/bashrc
fi

I have tried running "source .bashrc" but it doesn't change my aliases:

jdbrown@kitten jdbrown]$ alias
alias l.='ls -d .* --color=tty'
alias la='ls -aF --color'
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-tilde'

In other words, there seem to be some settings for ls and ll somewhere for which I am not able to override. The /etc/profile and /etc/bashrc files don't contain any alias commands. I do boot into xwindows, so I don't know if that affects anything. Any suggestions?

After making the alias changes, source the file as you have been doing and then type

alias

to see what they are set at.

That second quote is the output I get after sourcing the file and running alias. See the following:

[jdbrown@kitten jdbrown]$ cat .bashrc
# .bashrc

# User specific aliases and functions
alias la='ls -aF --color'
alias ls='ls -F --color'
alias ll='ls -alF --color'

# Source global definitions
if [ -f /etc/bashrc ]; then
. /etc/bashrc
fi
[jdbrown@kitten jdbrown]$ source .bashrc
[jdbrown@kitten jdbrown]$ alias
alias l.='ls -d .* --color=tty'
alias la='ls -aF --color'
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-tilde'

There are other aliases and I'm not sure where they are specified. Also it won't let me override a couple of them.

Here is /etc/profile:
[jdbrown@kitten jdbrown]$ cat /etc/profile
# /etc/profile

# System wide environment and startup programs, for login setup
# Functions and aliases go in /etc/bashrc

pathmunge () {
if ! echo $PATH | /bin/egrep -q "(^|:)$1($|:)" ; then
if [ "$2" = "after" ] ; then
PATH=$PATH:$1
else
PATH=$1:$PATH
fi
fi
}

# Path manipulation
if [ `id -u` = 0 ]; then
pathmunge /sbin
pathmunge /usr/sbin
pathmunge /usr/local/sbin
fi

pathmunge /usr/X11R6/bin after

unset pathmunge

# No core files by default
ulimit -S -c 0 > /dev/null 2>&1

USER="`id -un`"
LOGNAME=$USER
MAIL="/var/spool/mail/$USER"

HOSTNAME=`/bin/hostname`
HISTSIZE=1000

if [ -z "$INPUTRC" -a ! -f "$HOME/.inputrc" ]; then
INPUTRC=/etc/inputrc
fi

export PATH USER LOGNAME MAIL HOSTNAME HISTSIZE INPUTRC

for i in /etc/profile.d/*.sh ; do
if [ -r "$i" ]; then
. $i
fi
done

unset i

Here is /etc/bashrc:
[jdbrown@kitten jdbrown]$ cat /etc/bashrc
# /etc/bashrc

# System wide functions and aliases
# Environment stuff goes in /etc/profile

# by default, we want this to get set.
# Even for non-interactive, non-login shells.
if [ "`id -gn`" = "`id -un`" -a `id -u` -gt 99 ]; then
umask 002
else
umask 022
fi

# are we an interactive shell?
if [ "$PS1" ]; then
if [ -x /usr/bin/tput ]; then
if [ "x`tput kbs`" != "x" ]; then # We can't do this with "dumb" terminal
stty erase `tput kbs`
elif [ -x /usr/bin/wc ]; then
if [ "`tput kbs|wc -c `" -gt 0 ]; then # We can't do this with "dumb" terminal
stty erase `tput kbs`
fi

for i in /etc/profile.d/*.sh; do
if [ -r "$i" ]; then

Thanks,

check the files in /etc/profile.d
especially /etc/profile.d/colorls.csh

[DMR]

Right.

Those aliases are being set by the /etc/profile.d/colorls.sh and /etc/profile.d/which-2.sh scripts, which are called from the following section of /etc/profile:for i in /etc/profile.d/*.sh ; do
if [ -r "$i" ]; then
. $i
fi That little snippet basically says: "for every file which can be read in /etc/profile.d/, source that file".

One way to get around this would be to comment out the lines in those scripts which set the aliases you want to over-ride.

[jerbear]

Yep, that took care of it! Makes sense too. Thanks a bunch! Now back to my printer issues. Grrr.

Glad we could help you get it sorted (we'll be looking for that printer post).
