User:Mjb/tcsh configuration files

< User:Mjb
Jump to navigationJump to searchHere are the tcsh shell configuration files I use. I try to keep them compatible with csh but have not fully tested them there.
.login
# csh and tcsh .login
#
# This is for things that only need to be run once, at login.
#
# See .cshrc for both login and non-login shell settings, including
# things to do if you are changing shells after login.
# (tcsh only) warn if current terminal type isn't in termcap or terminfo
#
if ($?tcsh) then
if ( ! { (termname >& /dev/null) } ) then
echo "Terminal type '${term}' is unrecognized on this system."
echo " If you want to set a different type, use 'setenv <foo>'."
echo " If you want to keep this type but use another's capabilities, use 'tset <foo>'."
echo " Use 'termname <foo>' to see if foo is recognized on this system."
echo
endif
endif
# backspace and delete need to work the way I expect them to
#
stty sane
# see who's logged in
#
echo 'Users online:'
users
# In xterm-based terminals, set the window title before each prompt is displayed.
# This is here instead of in .cshrc because this particular title uses the initial
# login date & time for a particular host. If it were in .cshrc, it would update
# the login time each time an interactive csh or tcsh subshell is started.
#
if ( $?prompt && $TERM:s/-/./:r == "xterm" ) then
alias settitle printf '"\033]2;\!*\a\033]1;\!*\a\033]0;\!*\a"'

endif
# Some apps, like 'less' without the -X flag, like to switch to and from a
# separate screen buffer (actually cursor-addressing mode rather than
# memory-addressing mode). This capability is not on all terminals, and some
# terminals wipe the original buffer when switching back to it. These
# behaviors and their effects on terminal emulator scrollback buffers can be
# confusing for users.
#
# The switching is achieved by the ANSI code sequences assigned to terminal
# capabilities 'ti' & 'te' (termcap) or 'smcup' & 'rmcup' (terminfo). It can
# be disabled via a custom termcap or terminfo entry. Both work the same,
# amending an existing entry to disable the capabilities via '@' suffixes.
#
# Here we do it for xterm-256color:
#
if (-f /etc/termcap) then
# TERMCAP is the custom termcap entry itself
setenv TERMCAP ${TERM}:ti@:te@:tc=${TERM}
else if (-d /etc/terminfo && -X tic) then
# TERMINFO is a directory of tic(1)-compiled terminfo sources
setenv TERMINFO ~/.terminfo
setenv _TERMINFO_SOURCE ~/.terminfo-xterm-256color.src
echo "xterm-256color, smcup@, rmcup@, use=xterm-256color," >! ${_TERMINFO_SOURCE}
tic ${_TERMINFO_SOURCE}
unsetenv _TERMINFO_SOURCE
else
echo "Could not disable separate screen buffer."
endif
# warn if terminal size is undefined
#
if ( $?prompt && { ( stty -a | grep columns | egrep -q '0 rows; 0 columns|rows 0; columns 0' ) } ) then
echo "Terminal size is undefined; please 'stty rows # cols #' appropriately."
endif

.cshrc
# mjb's .cshrc
#
# Contains shell settings for csh and tcsh.
# On FreeBSD 4.1 and up, csh doesn't exist; it's a hard link to tcsh.
#
# Order of processing (login shells):
# 1. /etc/csh.cshrc
# 2. /etc/csh.login
# 3. ~/.tcshrc (if exists), else ~/.cshrc (this file)
# 4. file in 'histfile' shell variable (if exists), else ~/.history
# 5. ~/.login
# 6. file in 'dirsfile' shell variable (if exists), else ~/.cshdirs
#
# Order of processing (non-login shells):
# 1. /etc/csh.cshrc
# 2. ~/.tcshrc (if exists), else ~/.cshrc (this file)
#
# I use this .cshrc on multiple hosts, so it only contains settings
# common to all of them. At the end, it runs ~/.cshrc.local, which
# contains host-specific settings.

# Settings for all csh/cshrc instances running under my userid
#
### umask sets a mask for the default file permissions
umask 022 # unset group & others write, i.e. rw-r--r-- or rwxr-xr-x
### character encoding and localization preference
setenv LANG en_US.UTF-8 # another option is en_US.ISO8859-1
### misc program options
setenv BLOCKSIZE 1k # for /bin/ls
setenv GZIP '-9' # for /usr/bin/gzip

# * login shell (the shell instance you get at login)
# * non-login shells (any shell instances you invoke after login)
#
# This does not include shells referenced by script shebang lines unless they
# use -i, which would be very unusual. We could also use ($?loginsh) to test
# for -l or login shell, but there's not really anything that we would want
# to be exclusive to a login shell that we don't already do in ~/.login.
#
if ($?prompt) then
### improved key bindings
bindkey "^W" backward-delete-word # ctrl + W

bindkey "\e[1~" beginning-of-line # home
bindkey "\e[3~" delete-char # delete

### ctrl-D at prompt won't logout
set ignoreeof
### tab completion
set autolist
### complete filenames in csh (automatic for tcsh)
set filec
### beep only if no matches in filename completion attempt
set matchbeep = nomatch
### default typing mode (insert or overwrite)
set inputmode = insert
### save 1000 lines of history
set history = 1000
### restrict output redirection to not destroy existing files
set noclobber
### aliases could be set in .login, but here is better (esp. for 'su')
if (-f ~/.alias) source ~/.alias
### ask for confirmation before doing 'rm *'
set rmstar
### CVS related
setenv CVS_RSH ssh

### enable color output for ls-F (shell builtin)
### without args, ls-F calls /bin/ls -F and colorizes as per LS_COLORS, below
### with args, ls-F calls /bin/ls -F, plus /bin/ls's color flag:
### on most systems, it's --color=auto (as used by GNU ls)
### on BSD, it's -G (colors as per LSCOLORS, below)
### on BSD, CLICOLOR being set forces -G behavior even if 'color' is unset!

### enable color output for BSD /bin/ls (has same effect as /bin/ls -G)
### CLICOLOR_FORCE is needed to keep color when piping ls output to 'less'
### CLICOLOR_FORCE may interfere with programs that parse ls output!
setenv CLICOLOR
setenv CLICOLOR_FORCE
### color codes for BSD /bin/ls with CLICOLOR set or with -G
setenv LSCOLORS GxDxBeCbCxExhxfxgxfxgx
### enable color in GNU grep
setenv GREP_OPTIONS --color=auto
### set temporary variables for ANSI text formatting with color
### ';5;nnn' assumes extended color is available.
