gentoo下如何安装expect包中的 kibitz

emerge -av dev-perl/Expect tcl

emerge -pf expect

cd /usr/src

wget

tar zxvf expect-5.42.1.tar.gz

cp example/kibitz /usr/bin/

cp example/xkibitz /usr/bin/

vim /usr/bin/kibitz

 

将前面几行改为

#!/bin/sh
# \
    exec expect -- "$0" ${1+"$@"}
##!../expect --

 

就可以使用 kibitz 了

 

例如：

w

显示

root pts/0

root pts/2 

#kibitz -tty pts/2 root 

asking root to type:  kibitz -30993

 

pts/2上显示：

Message from on pts/0 at 17:42 ...
Can we talk? Run: kibitz -30993
EOF

kibitz -30993(复制kibitz -30993并回车)
Escape sequence is ^]

#w

USER     TTY         PCPU WHAT
root     pts/0       0.00s expect -- /usr/bin/kibitz -tty pts/2 root
root     pts/2       0.00s expect -- /usr/bin/kibitz -30993

 

这样两个用户就看到同一个SHELL的显示了
