问题描述
我正在尝试将期望脚本实现为bash脚本.请耐心等待,因为我还不熟悉bash/expect.
I am trying to implement an expect script into a bash script. Bear with me since I am fairly new to bash/expect.
这是预期的脚本,可以按预期工作:
Here is the expect script that works as intended:
log_user 0
file delete foo.txt
set fh [open foo.txt a]
set servers {xxx@server1 xxx@server2}
foreach s $servers {
spawn ssh $s
expect "password: "
send "PASSWORD\r"
expect "$ "
send "grep "something" /some/log/file.log"
expect "$ " { puts $fh "$expect_out(buffer)"}
send "exit\r"
}
close $fh
现在,我希望将此期望脚本包含在bash脚本中,但是它不能按预期工作.
Now, I am hoping to include this expect script in a bash script but it is not working as intended.
这是我到目前为止所拥有的:
Here is what I have so far:
#!/bin/bash
XYZ=$(expect -c "
file delete foo.txt
set fh [open foo.txt a]
set servers {xxx@server1 xxx@server2}
foreach s $servers {
spawn ssh $s
expect "password: "
send "PASSWORD\r"
expect "$ "
send "grep "something" /some/log/file.log"
expect "$ " { puts $fh "$expect_out(buffer)"}
send "exit\r"
}
close $fh
")
echo "$XYZ"
我得到的错误是:
command substitution: line 42: syntax error near unexpected token `('
command substitution: line 42: `expect "$ " { puts $fh "$expect_out(buffer)"}'
我愿意采用任何其他方式来实现这一目标! :)
I'm open to any other ways to implement this! :)
推荐答案
您可以使用/usr/bin/expect -c
执行expect
命令:
#!/bin/bash
/usr/bin/expect -c '
file delete foo.txt
set fh [open foo.txt a]
set servers {xxx@server1 xxx@server2}
foreach s $servers {
spawn ssh $s
expect "password: "
send "PASSWORD\r"
expect "$ "
send "grep "something" /some/log/file.log"
expect "$ " { puts $fh "$expect_out(buffer)"}
send "exit\r"
}
close $fh
'
