注:这里是bash环境,如果是csh请把export改成setenv 并用setenv用法(其实就是setenv HISTSIZE 100),在bash中可以把下面内容放在~/.bashrc或者是~/.bash_profile 中,如果是csh就放在~/.cshrc,如果想对所有用户生效,请放在/etc/profile中,一般这些文都有内容可以接着下面写。 1,历史命令记录数100条 #1,Environment variables export HISTSIZE=100 2,PS1值 #2,Sheel prompt-Bash export PS1="\t \u@\h (\w) [\!]$" 3,MASK值,新建文件夹权限700,新建文件权限600 #3,File creation mask umask 077 4,STTY #4,Terminal settings (for remote host only) stty erase ^H 5,DATE #5,Display welcome message echo "Welcome tao" echo "Today is `date`." echo 6,系统登录用户信息 #6,System information echo "Last three logins:";last `logname` |head -3 echo echo "Current users: `users`" echo echo "System uptime:";uptime echo echo "There are `who | wc -l` userids logged in right now." 7,默认编辑器VIM ,翻页器LESS #8,default pager ,editor export PAGER=less export LESS='-CFMs' export EDITOR=vim 8,如果没有操作默认300秒断开 export TMOUT=300 9,给MAN命令加上颜色 9# man pages in color export LESS_TERMCAP_mb=$'\E[01;31m' export LESS_TERMCAP_md=$'\E[01;31m' export LESS_TERMCAP_me=$'\E[0m' export LESS_TERMCAP_se=$'\E[0m' export LESS_TERMCAP_so=$'\E[01;44;33m' export LESS_TERMCAP_ue=$'\E[0m' export LESS_TERMCAP_us=$'\E[01;32m'j
