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.
This package is known to build and work properly using an LFS-11.1 platform.

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-6.24.00/html && install -v -m644 tcsh.html/* /usr/share/doc/tcsh-6.24.00/html && install -v -m644 FAQ /usr/share/doc/tcsh-6.24.00
--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.
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"
