Tcsh の概要

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.

本パッケージは LFS-8.0 において正しくビルドでき動作することが確認されています。

Package Information


Tcsh のインストール

First, fix the package for tool chain changes:

sed -i 's|SVID_SOURCE|DEFAULT_SOURCE|g' config/linux  &&
sed -i 's|BSD_SOURCE|DEFAULT_SOURCE|g'  config/linux

以下のコマンドを実行して Tcsh をビルドします。

./configure --prefix=/usr --bindir=/bin &&

make &&
sh ./tcsh.man2html

ビルド結果をテストる場合は make check を実行します。

root ユーザーになって以下を実行します。

make install &&

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-6.20.00/html &&
install -v -m644 tcsh.html/* /usr/share/doc/tcsh-6.20.00/html &&
install -v -m644 FAQ         /usr/share/doc/tcsh-6.20.00


--bindir=/bin: これは tcsh プログラムのインストール先を /usr/bin ではなく /bin とします。

sh ./tcsh.man2html: これは、書式化された man ページから HTML ドキュメントを生成します。

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.

Tcsh の設定


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"

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:

# 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.  Two separate versions for you to try, pick
# whichever one you like better, and change the colors as you want.
# Just don't mess with the ${end} guy in either line...  Comment out or
# delete the prompt you don't use.

set prompt="${green}%n${blue}@%m ${white}%~ ${green}%%${end} "
set prompt="[${green}%n${blue}@%m ${white}%~ ]${end} "

# This was not in the original URL above
# Provides coloured ls
alias ls ls --color=always

# Clean up after ourselves...
unset red green yellow blue magenta cyan yellow white end
