在 expect 输出中搜索单词

Question

我有一个期望命令

expect "~]#" { send "virsh list --all\r"}

输出为

[root@lht1oneems-unit0 ~]# virsh list --all
 Id    Name                           State
----------------------------------------------------
 399   lht1duplexvm-0                 running
 -     rhelvm                         shut off

我想使用 $expect_out(buffer) 并使用 if 语句在找到运行时执行某些操作，否则执行其他操作。如何解析 $expect_out(buffer)?

的结果

Answer 1

expect "~]#"
send "virsh list --all\r"

# I assume another prompt follows this
expect "~]#"

if { [regexp {running} $expect_out(buffer)] } {
    do-something-for-running-process
} else {
    do-something-for-no-running-process
}

你也可以

if {[string first "running" $expect_out(buffer)] >= 0} {
