Linux Shell-Expect调用shell里的变量

 

先看上一文章中expect里的脚本:

[root@mail root]# more getdata.sh
#!/usr/bin/expect
set password 123456

spawn /usr/bin/scp /web/backup/
expect "password"
send "$password"
send "\n"
interact

这时你会发现红色字体为日期参数yyyy-mm-dd.

如何用shell里的date命令进行引用呢.实在没办法,对角本进行如下处理.

[root@mail tmp]# more getdata.sh
#!/usr/bin/expect
set password 123456

set DATE [lindex $argv 0]
spawn /usr/bin/scp /web/backup/
expect "password"
send "$password"
send "\n"
interact

[root@mail tmp]# more scpdata.sh
#!/bin/sh

DATE=`/bin/date +%Y%m%d`
timestamp=`date +%Y-%m-%d`

/tmp/getdata.sh $timestamp

2010-12-14再次查看CU,有高人给出这样的脚本.很给力.

#!/usr/bin/expect -f
set password 123456
set date [exec date "+%Y-%m-%d"]
spawn /usr/bin/scp ://backup/test-file-$date /test/backup/
expect "assword:"
send -- "$password\r"
expect "assword:"
send -- "$password\r"
expect eof
