238Chapter 10Integrated <strong>Development</strong> EnvironmentsUncompress the archive:bunzip2 NetBeansIDE-release35.tar.bz2This will leave the file NetBeansIDE-release35.tar in place of the.bz2 file.You can examine the contents of the TAR file with:tar -tvf NetBeansIDE-release35.tar | moreHere the options (-tvf) specify to show a table of contents (-t) in verbose,that is, long, form (-v) from the specified file (-f) followed by the TARfilename. The output from tar here is piped into more so that you can pagethrough it. Type q when you’ve seen enough, or leave off the | more to let itrun through without pausing.Notice that the names of all the files in the TAR archive begin withnetbeans/ which tells us that if we untar the file, it will put all the files into adirectory called netbeans. Therefore, we don’t need to make such a folderbeforehand.Change directory to the directory where you would like to installNetBeans. If you are on a system that may be used by different users, you’llprobably want to put it in a more public location like /usr/local or /opt. Ifit is for your personal use, you can put it anywhere—just be sure that you havewrite permissions on the directory where you want to install NetBeans.(Reminder: use ls -ld . to see the permissions of the current directory.)The tar command to untar everything in place is simple:tar -xf NetBeansIDE-release35.tarThis will extract (-x) all the files that are in the TAR file (-f) namedNetBeansIDE-release35.tar. If you’d like to see each file get named as itis extracted, then change the -xf to -xvf (v for verbose) and you will see awhole long list of filenames displayed on your screen as the file is unpacked.Next, we need to adjust the startup parameter in the configuration file.The file is in the netbeans directory that you just untarred. In there is a directorynamed bin, and in there is a file called ide.cfg. Open this file with aneditor and change the line that begins -jdkhome so that the pathname refersto the location of your Java <strong>Development</strong> Kit (JDK, see Chapter 5).Here’s an example of the contents of ide.cfg:
