I have created a little script to add bookmarks in Nautilus to redirect users to network share. If I run the script manually, it works brillantly but as soon as I try to add it in /etc/profile.d, I can't connect to the computer. It seems that as soon as I do a loop or anything "fancy" like that, the script give an error. Here is an example if my currently working script :


# Creating gtk-bookmarks if it doesn't exists
if [[ ! -f ~/.gtk-bookmarks ]]
        touch ~/.gtk-bookmarks

# Adding bookmarks if not present
if ! grep -Fxq "smb:// Software:" ~/.gtk-bookmarks
    echo "smb:// Software:" >> ~/.gtk-bookmarks

As soon as I had a function like this one :

# Function find_server_by_ip()
# Desc : This function find the server to use for the current host IP Address
# Parameters : None
# Return : echo Server to use
function find_server_by_ip()
        hostname_ip=$(hostname -I)
        set -- $hostname_ip

        if [[ $3 -eq 78 ]]
                echo "Server A"
                echo "Server B"

...login stop working. What baffles me is that running this script with *bash* or *./* works fine...

Is it possible that we can't create functions, parse arrays or anything like that in a script called by /etc/profile? And in that case, where or how can I execute a login script for all the users connecting to the computer? Oh, by the way I am running Ubuntu 12.04 LTS!

Thanks in advance and sorry for my english!

EDIT : There is a pastebin of the script. I don't add it compeletly since the script comments are in french so...well, there it is :

Stuff in /etc/profile.d is probably sourced by your window manager when you log in, and that probably uses /bin/sh, so target a POSIX shell, not bash, for scripts to be added there. Note that [[ is not found in the scripts that are in there now.


  • choose [ ... ] over [[ ... ]]
  • use funcname() { ... } without the function keyword

dash is a POSIX (only) shell, so you might find the dash man page handy

Comments on

  • This is the primary error: Change

    if [[ ! -f ~/.gtk-bookmarks ]]


     if [ ! -f ~/.gtk-bookmarks ]
  • the find_server_by_ip function can be simplified:

    findserverbyip() {
        case "$(hostname -I)" in 
            *[0-9].33.9.[0-9]*) share_server=serverB ;;
            *)                  share_server=serverA ;;

    Also, this comment is misleading: the function returns nothing, it has a side effect.

    # Return : echo Server to use
  • might as well remove the shebang line: this script doesn't get executed, it gets sourced.

Note that goes for your ~/.profile too. – glenn jackman Mar 19 '14 at 20:37
Thanks for the fast reply! Unfortunately I tried to remove everything not "sh"-compliant and still the same problem. I'm starting to think that the problem is caused by /etc/profile that "source" the script, not execute them alongside himself...?? – Patrick Pruneau Mar 19 '14 at 20:51
show (or link to) the whole script. – glenn jackman Mar 19 '14 at 20:57
I added a link to pastebin with the (almost) whole script in the question. – Patrick Pruneau Mar 20 '14 at 12:58
