变量名称必须以 .cshrc 上的字母开头

Question

我想调整 .cshrc 如下：

# $FreeBSD: src/share/skel/dot.cshrc,v 1.14.6.1 2008/11/25 02:59:29 kensmith Exp $
#
# .cshrc - csh resource script, read at beginning of execution by each shell
#
# see also csh(1), environ(7).
#

alias h     history 25
alias j     jobs -l
alias la    ls -a
alias lf    ls -FA
alias ll    ls -lA

# A righteous umask
umask 22

set path = (/sbin /bin /usr/sbin /usr/bin /usr/local/sbin /usr/local/bin $HOME/bin)



setenv  EDITOR  vi
setenv  PAGER   more
setenv  BLOCKSIZE   K
setenv  PKG_DBDIR   ~/db/pkg

if ($?prompt) then
    # An interactive shell -- set some stuff up
    set filec
    set history = 100
    set savehist = 100
    set mail = (/var/mail/$USER)
    if ( $?tcsh ) then
        bindkey "^W" backward-delete-word
        bindkey -k up history-search-backward
        bindkey -k down history-search-forward
    endif
endif
set path = ($path $HOME/local/python/bin)

但是当我这样做时发生了错误source .shrc
