Tcsh-6.24.10

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.

Tcsh のインストール

以下のコマンドを実行して Tcsh をビルドします。

./configure --prefix=/usr &&
make

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 install.man &&

ln -v -sf tcsh   /bin/csh &&
ln -v -sf tcsh.1 /usr/share/man/man1/csh.1

コマンド説明

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

設定ファイル

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.

設定情報

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.  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
EOF
