%general-entities; ]> $Date$ Tcsh The Tcsh package contains an enhanced but completely compatible version of the Berkeley Unix C shell (csh). This is useful as an alternative shell for those who prefer C syntax to that of the bash shell, and also because some programs require the C shell in order to perform installation tasks. &lfs101_checked; Package Information Download (HTTP): Download (FTP): Download MD5 sum: &tcsh-md5sum; Download size: &tcsh-size; Estimated disk space required: &tcsh-buildsize; Estimated build time: &tcsh-time; User Notes: Install Tcsh by running the following commands: ./configure --prefix=/usr --bindir=/bin && make && sh ./tcsh.man2html To test the results, issue: make check. Now, as the root user: make install install.man && ln -v -sf tcsh /bin/csh && ln -v -sf tcsh.1 /usr/share/man/man1/csh.1 && install -v -m755 -d /usr/share/doc/tcsh-&tcsh-version;/html && install -v -m644 tcsh.html/* /usr/share/doc/tcsh-&tcsh-version;/html && install -v -m644 FAQ /usr/share/doc/tcsh-&tcsh-version; --bindir=/bin: This installs the tcsh program in /bin instead of /usr/bin. sh ./tcsh.man2html: This creates HTML documentation from the formatted man page. ln -v -sf tcsh /bin/csh: The FHS states that if there is a C shell installed, there should be a symlink from /bin/csh to it. This creates that symlink. There are numerous configuration files for the C shell. Examples of these are /etc/csh.cshrc, /etc/csh.login, /etc/csh.logout, ~/.tcshrc, ~/.cshrc, ~/.history, ~/.cshdirs, ~/.login, and ~/.logout. More information on these files can be found in the tcsh(1) man page. /etc/csh.cshrc /etc/csh.login /etc/csh.logout ~/.tcshrc ~/.cshrc ~/.history ~/.cshdirs ~/.login ~/.logout Update /etc/shells to include the C shell program names (as the root user): cat >> /etc/shells << "EOF" /bin/tcsh /bin/csh EOF The following ~/.cshrc provides two alternative colour prompts and coloured ls output. If you prefer a global modification, issue the command as the root user, replacing ~/.cshrc by /etc/csh.cshrc. cat > ~/.cshrc << "EOF" # Original at: # https://www.cs.umd.edu/~srhuang/teaching/code_snippets/prompt_color.tcsh.html # Modified by the BLFS Development Team. # Add these lines to your ~/.cshrc (or to /etc/csh.cshrc). # Colors! set red="%{\033[1;31m%}" set green="%{\033[0;32m%}" set yellow="%{\033[1;33m%}" set blue="%{\033[1;34m%}" set magenta="%{\033[1;35m%}" set cyan="%{\033[1;36m%}" set white="%{\033[0;37m%}" set end="%{\033[0m%}" # This is needed at the end... # Setting the actual prompt.
