外壳脚本！语法错误：意外的“(”

Question

在对第一个答案进行更改后，我收到了更多错误代码。

: not found: line 23: {

esxidown.sh: line 24: redir error
Insufficient arguments.

: not found: line 26:

esxidown.sh: line 53: syntax error: unexpected word (expecting "do")

我尝试运行的脚本出现问题。

情况是：我有一个 UPS，想要获取一个脚本来关闭我的虚拟机，然后在 UPS 开始运行时关闭主机。

我已经找到了一个应该安全关闭虚拟机然后关闭主机的脚本。

但我收到以下错误：语法错误：意外的“（”

未经个人修改的脚本：

#!/bin/sh
# ESXi 5.1 host automated shutdown script

# these are the VM IDs to shutdown in the order specified
# use the SSH shell, run "vim-cmd vmsvc/getallvms" to get ID numbers
# specify IDs separated by a space
SERVERIDS=$(vim-cmd vmsvc/getallvms | sed -e '1d' -e 's/ \[.*$//' | awk '$1 ~ /^[0-9]+$/ {print $1}')

# New variable to allow script testing, assuming the vim commands all work to issue shutdowns
# can be "0" or "1"
TEST=0

# script waits WAIT_TRYS times, WAIT_TIME seconds each time
# number of times to wait for a VM to shutdown cleanly before forcing power off.
WAIT_TRYS=20

# how long to wait in seconds each time for a VM to shutdown.
WAIT_TIME=10

# ------ DON'T CHANGE BELOW THIS LINE ------

validate_shutdown()
{
    vim-cmd vmsvc/power.getstate $SRVID | grep -i "off" > /dev/null 2<&1
    STATUS=$?

    if [ $STATUS -ne 0 ]; then
if [ $TRY -lt $WAIT_TRYS ]; then
        # if the vm is not off, wait for it to shut down
        TRY=$((TRY + 1))
        echo "Waiting for guest VM ID $SRVID to shutdown (attempt #$TRY)..."
        sleep $WAIT_TIME
        validate_shutdown
    else
        # force power off and wait a little (you could use vmsvc/power.suspend here instead)
        echo "Unable to gracefully shutdown guest VM ID $SRVID... forcing power off."
        if [ $TEST -eq 0 ]; then
vim-cmd vmsvc/power.off $SRVID
        fi
sleep $WAIT_TIME
    fi

}

# enter maintenance mode immediately
echo "Entering maintenance mode..."
if [ $TEST -eq 0 ]; then
esxcli system maintenanceMode set -e true -t 0 &

# read each line as a server ID and shutdown/poweroff
for SRVID in $SERVERIDS

vim-cmd vmsvc/power.getstate $SRVID | grep -i "off\|Suspended" > /dev/null 2<&1

echo "Exiting maintenance mode..."
if [ $TEST -eq 0 ]; then
esxcli system maintenanceMode set -e false -t 0

# exit the session
exit

这并不符合您的想法：

SERVERIDS=1 2 3 4(vim-cmd vmsvc/getallvms | sed -e '1d' -e 's/ \[.*$//' | awk '$1 ~ /^[0-9]+$/ {print $1}')

这将仅为该命令设置，然后使用参数和SERVERIDS=1运行“命令” ，后者不是有效的语法。234(...)使用更多引号，你可能想要这样的东西：

SERVERIDS="1 2 3 4 $(vim-cmd vmsvc/getallvms | sed -e '1d' -e 's/ \[.*$//' | awk '$1 ~ /^[0-9]+$/ {print $1}')"
