Need to insert text after a specific line of text.

[aenagy]

I am trying to update '/etc/profile' to add an entry to $PATH. What I would like to do is insert the new path as the last entry in $PATH, but only for root.

This is the text I want to modify:

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

What I need is:

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

I could simply append the following to the end of '/etc/profile', but I was hoping for a more elegant solution.

# Path manipulation
if [ `id -u` = 0 ]; then
        pathmunge /opt/Navisphere/bin after
fi

Any help would be appreciated.

Thanks.

# Path manipulation
if [ `id -u` = 0 ]; then
PATH=$PATH:/opt/myapplication/bin
fi

Hope the above helps.
