Users who still worry about the new version breaking things may install <A NAME="tex2html1940" HREF="http://gmt.soest.hawaii.edu"><B>GMT</B></A> 3.4.x versions and 4.x and use our utility <I>gmtswitch</I><A NAME="33754"></A> to select their current version should the need to switch arises. You will find <I>gmtswitch</I><A NAME="33757"></A> in the top-level <A NAME="tex2html1941" HREF="http://gmt.soest.hawaii.edu"><B>GMT</B></A>4.x directory; install as explained below. <P> Because <A NAME="tex2html1942" HREF="http://gmt.soest.hawaii.edu"><B>GMT</B></A> 4.x is backwards compatible with the 3.4.x series yet maintains its parameters and history in separate hidden files (e.g., <U>.gmtdefaults4</U> versus <U>.gmtdefaults</U>) it is possible to install and use both versions on the same workstation. To simplify such setups we supply the utility <I>gmtswitch</I><A NAME="33768"></A> which simplifies switching back and forth between any number of installed <A NAME="tex2html1943" HREF="http://gmt.soest.hawaii.edu"><B>GMT</B></A> 3-versions and <A NAME="tex2html1944" HREF="http://gmt.soest.hawaii.edu"><B>GMT</B></A> 4.x. Place the <I>gmtswitch</I><A NAME="33777"></A> Bourne shell script in your general executable path (not in one of the <A NAME="tex2html1945" HREF="http://gmt.soest.hawaii.edu"><B>GMT</B></A> bin directories) and run it after you have finished installing all <A NAME="tex2html1946" HREF="http://gmt.soest.hawaii.edu"><B>GMT</B></A> versions of interest. The first time you run <I>gmtswitch</I><A NAME="33786"></A> it will try to find all the available versions installed on your file system. The versions found will be listed in the file <U>.gmtversions</U> in your home directory; each line is the full path to a <A NAME="tex2html1947" HREF="http://gmt.soest.hawaii.edu"><B>GMT</B></A> root directory (e.g., /usr/local/GMT3.4.2). You may manually add or remove entries there at any time. You are then instructed to make two changes to your environment (the details are shell-dependent but explained by <I>gmtswitch</I><A NAME="33793"></A>): <OL> <LI><I>gmtswitch</I><A NAME="33796"></A> creates and maintains a symbolic link <U>this_gmt</U> in your home directory that will point to a directory with one of the installed GMT versions. </LI> <LI>Make sure <B>$HOME</B>/this_gmt/bin is in your executable <B>PATH</B>. </LI> </OL> Make those edits, logout, and log and back in again. The next time you run <I>gmtswitch</I><A NAME="33800"></A> you will be able to switch between versions. Typing <I>gmtswitch</I><A NAME="33803"></A> with no argument will list the available versions in a numerical menu and prompt you to choose one, whereas <I>gmtswitch</I><A NAME="33806"></A> <I>version</I> will immediately switch to that version (<I>version</I> must be a piece of unique text making up the full path to a version, e.g., 3.4.2). If you use <I>tcsh</I><A NAME="33809"></A> or <I>csh</I><A NAME="33812"></A> you may have to type ``rehash'' to initiate the path changes. <P> <HR> <!--Navigation Panel--> <A NAME="tex2html6252" HREF="node255.html"> <IMG WIDTH="37" HEIGHT="24" ALIGN="BOTTOM" BORDER="0" ALT="next" SRC="next.png"></A> <A NAME="tex2html6246" HREF="node252.html"> <IMG WIDTH="26" HEIGHT="24" ALIGN="BOTTOM" BORDER="0" ALT="up" SRC="up.png"></A> <A NAME="tex2html6242" HREF="node253.html"> <IMG WIDTH="63" HEIGHT="24" ALIGN="BOTTOM" BORDER="0" ALT="previous" SRC="prev.png"></A> <A NAME="tex2html6248" HREF="node1.html"> <IMG WIDTH="65" HEIGHT="24" ALIGN="BOTTOM" BORDER="0" ALT="contents" SRC="contents.png"></A> <A NAME="tex2html6250" HREF="node255.html"> <IMG WIDTH="43" HEIGHT="24" ALIGN="BOTTOM" BORDER="0" ALT="index" SRC="index.png"></A> <BR> <B> Next:</B> <A NAME="tex2html6253" HREF="node255.html">Index</A> <B> Up:</B> <A NAME="tex2html6247" HREF="node252.html">P.
