<br>Do I include the word 'export'? <br></div></div></blockquote><div><br></div><div>Yes. PATH is simply a variable used to hold the list of directories. You *can* do just 'PATH=$PATH:/usr/opt', but including the export is a better, more recommended way to do it. This will immediately change the value for the currently logged in shell session *only*<br>

</div></div></blockquote><div><br>Editing '/home/paul/.bashrc' would be *account* wide -- all *new* shell sessions you open will have the updated value -- but not the existing ones. This should also include the shell used in Alt-F2, but I don't use that feature, so I am not sure.<br>
<br></div><div>To go 'system wide' you would usually edit /etc/bashrc or add a new script to /etc/profile.d/ with the changes you want. These correspond to .bashrc and .bash_profile -- the .bashrc in your home directory will *include* /etc/bashrc, so these changes will appear for all users. Various distrobutions handle these two files differently. I am used to Red Hat based systems, and I have always been told use the bashrc files for functions and aliases, and .bash_profile for environmental variables -- but I tend to put everything in .bashrc anyway. <br>
<br></div><div>These two files behave slightly differently, and rather than explain it myself, I am going to refer you to a resource I found via my good friend Google:<br><a href="http://www.joshstaiger.org/archives/2005/07/bash_profile_vs.html" target="_blank">http://www.joshstaiger.org/archives/2005/07/bash_profile_vs.html</a><br>

Maybe the .bash_profile file is on different distro's I do not know yet.<br>
