这是上个月学习VIO SERVER时，写的东西，目的是修改环境变量PS1，让提示符中出现时间、用户名、机器名、路径名4种信息。

 

    方法：oem_setup_env后，执行下面的命令。
echo export ENV=/home/padmin/.kshrc >>/etc/profile

cat <<'!' >/home/padmin/.kshrc
set -o vi

SECONDS="$(date '+3600*%H+60*%M+%S')"
typeset -Z2 _h; typeset -Z2 _m ; typeset -Z2 _s
_time='${_x[(_h=(SECONDS/3600)%24)(_m=(SECONDS/60)%60)(_s=(SECONDS)%60)]}$_h:$_m:$_s'
export SECONDS _h _m _s _time

if [ $0 != "/usr/ios/cli/man.ksh" ]
then
 alias | grep -q ioscli
 if [ $? == 0 ]
 then
  export PS1=$(echo ${_time})" `who am i | awk '{print $1}'`@`hostname`"':[$PWD]$'
 else
  export PS1=$(echo ${_time})" `whoami`@`hostname`"':[$PWD]#'
 fi
fi
!

 

    下面是效果：
telnet (vio)
