Cài đặt TCSH

This appendix describes how to obtain, build, test, and install tcsh. As I write, tcsh is at version 6.06. If a more recent version has been released, just substitute the new version number wherever you see 6.06 in those commands in which it appears below.V | Obtaining Installing tcsh This appendix describes how to obtain build test and install tcsh. As I write tcsh is at version 6.06. If a more recent version has been released just substitute the new version number wherever you see 6.06 in those commands in which it appears below. The first thing you should do is check whether or not an up to date tcsh is already installed on your system. If it is you don t need to do anything except make tcsh your login shell. See Selecting a Shell in Chapter 1 Introduction. Otherwise get the current version and install it first. Find out whether tcsh is installed and what its pathname is by asking your system administrator or by running this command which tcsh If tcsh is present determine its version number using the following command. Use single quotes as shown but substitute the actual pathname if it s different than bin tcsh bin tcsh -c echo version tcsh 6.00.02 Cornell 08 05 91 options 8b nls dl al dir If the output of this command indicates that your tcsh is an old version as it does here you should get the current one. Obtaining the Source Distribution The tcsh source distribution is available on the Internet via anonymous FTP. Connect to tesla.ee.cornell.edu change into the pub tcsh directory and transfer the file tcsh-6.06.tar.gz in binary mode. After you obtain the distribution uncompress it and extract the files gunzip tcsh-6.06.tar.gz tar xf - Or on System V systems gunzip tcsh-6.06.tar.gz tar xof - If you don t have gunzip specify the filename without the .gz suffix as tcsh-6.06.tar when you get the distribution. The FTP server will uncompress the file for you. Then run one of these commands tar xf tcsh-6.06.tar For non-System V systems tar xof tcsh-6.06.tar For System V systems The tar command should produce a directory tcsh-6.06 in your current directory. Change into that directory with cd tcsh-6.06 and you re ready to begin the build process. If you want to use a World Wide Web browser to obtain the distribution use .
