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?

.sh
, it is irrelevant and anyway the files inprofile.d
are sourced, not executed which is slightly different and does not require the file to be executable. The issue here is thatprofile
&co are not read by non-login scripts..bashrc
and all your problems will go away. There is also a question of precedence, if one of the files that are read subsequently also sets PS1, then the previous value will be discarded. Anyway, seriously, don't touch the filers in/etc
, play with the ones in your home dir and use.bashrc
not profile..profile
files in your home and the settings there will overwrite anything you do in/etc/profile
. Basically never touch/etc
unless you know what you're doing. That's what the user-specific files are for. Also, please edit your question and explain exactly how you are connecting, that changes everything./etc/profile.d
that is a really bad idea and will affect all users of the system. Just include the commands fromprofile_local.sh
in your~/.profile
or simply source the script by adding this line to your~/.profile
:. /path/to/profile_local.sh
. (the.
meanssource
, it will read the file you give it and run the commands it finds there).
