Question

我有以下用于OSX的shell脚本我想用来纠正/修复用户目录的权限，但是我收到了错误：

bash-3.2# sh fix-perms.sh 
fix-perms.sh: line 23: syntax error near unexpected token `else'
fix-perms.sh: line 23: `else'

我的剧本：

#!/bin/sh

# Script fixes permissions in Users directory

#  Set PATH as shortcut
#
PATH=/bin:/usr/bin:/sbin:/usr/sbin export PATH

# First verify volume is mounted before executing

if [ -d /Volumes/UserStorage ] ;
then

        USERS=`mktemp -t users-XXXXX.log`
        ls -1 /Volumes/UserStorage/Users > $USERS

        for i in `cat $USERS`; do
        chmod -R 700 /Volumes/UserStorage/Users/$i

        find /Volumes/UserStorage/Users/$i -type d -exec chmod 701 {} \;
        exit 0

else

echo Volume Not Mounted

exit 1

fi

我必须是愚蠢/愚蠢的东西，但是如果我能看到它就会变得愚蠢！

提前感谢您的提示/见解。

Answer 1

问：你是否意识到你在你的循环中错过了“完成”？

问：如果你将“then”与分号放在同一行会怎样？

以下是一些例子：

这是您的原始代码，略有修改：

#!/bin/sh
# Script fixes permissions in Users directory
#  Set PATH as shortcut
#
PATH=/bin:/usr/bin:/sbin:/usr/sbin export PATH

# First verify volume is mounted before executing
if [ -d /Volumes/UserStorage ] ; then
        USERS=`mktemp -t users-XXXXX.log`
        ls -1 /Volumes/UserStorage/Users > $USERS

        for i in `cat $USERS`; do
          chmod -R 700 /Volumes/UserStorage/Users/$i

          find /Volumes/UserStorage/Users/$i -type d -exec chmod 701 {} \;
          exit 0
        done

else
  echo Volume Not Mounted
  exit 1
fi

Answer 2

您在done循环中忘记了for。语法是：

for statement
do
  statements...
done
