set fh [open foo.txt a]
set servers {xxx@server1 xxx@server2}
foreach s $servers {

send "PASSWORD\r"
expect "$ "
send "grep "something" /some/log/file.log"
expect "$ " { puts $fh "$expect_out(buffer)"}
send "exit\r"
}

这是我到目前为止所拥有的：
#!/bin/bash
XYZ=$(expect -c "
file delete foo.txt
set fh [open foo.txt a]
set servers {xxx@server1 xxx@server2}
foreach s $servers {
