I'm new to Ubuntu. I'm running 13.10 Desktop.
I wanted to set some system wide aliases and a custom prompt for bash. I found this article:
https://help.ubuntu.com/community/EnvironmentVariables
Following the advice in this article, I created /etc/profile.d/profile_local.sh. It is owned by root and has permissions of 644 just like the other scripts there:
root@ubuntu:/etc/profile.d# ll
total 28
drwxr-xr-x 2 root root 4096 Mar 23 08:56 .
drwxr-xr-x 135 root root 12288 Mar 23 09:15 ..
-rw-r--r-- 1 root root 660 Oct 23 2012 bash_completion.sh
-rw-r--r-- 1 root root 3317 Mar 23 07:36 profile_local.sh
-rw-r--r-- 1 root root 1947 Nov 23 00:57 vte.sh
I have further confirmed that /etc/profile calls /etc/profile.d. It contains this code block:
if [ -d /etc/profile.d ]; then
for i in /etc/profile.d/*.sh; do
if [ -r $i ]; then
. $i
fi
done
unset i
fi
Upon login, it does not appear that the custom script, profile_local.sh I created gets sourced. However if after login I 'source /etc.profile.d/profile_local.sh', I get the expected behavior, my custom aliases, and custom prompt.
What am I doing wrong?
Contents of script 'profile_local.sh':
# 3/23/14 - Copied from Gentoo /etc/bash/bashrc
# Placed in /etc/profile.d as described at:
# https://help.ubuntu.com/community/EnvironmentVariables
This file is sourced by all interactive bash shells on startup,
including some apparently interactive shells such as scp and rcp
that can't tolerate any output. So make sure this doesn't display
anything or bad things will happen !
Test for an interactive shell. There is no need to set anything
past this point for scp and rcp, and it's important to refrain from
outputting anything in those cases.
if [[ $- != i ]] ; then
# Shell is non-interactive. Be done now!
return
fi
Bash won't get SIGWINCH if another process is in the foreground.
Enable checkwinsize so that bash will check the terminal size when
it regains control. #65623

shopt -s checkwinsize

dircolors --print-database uses its own built-in database
instead of using /etc/DIR_COLORS. Try to use the external file
first to take advantage of user additions. Use internal bash
globbing instead of external grep binary.
