Question

这是我的第一天脚本，我使用linux但需要一个脚本，我一直绞尽脑汁直到我终于寻求帮助。我需要检查一个已经存在目录的目录，看看是否添加了任何不期望的新目录。

好的，我想我已尽可能简单了。以下工作但也显示目录中的所有文件。 我将继续努力，除非有人能告诉我如何不列出文件 |我试过ls -d但它正在做回声＆＃34;没什么新的＆＃34;。我觉得自己像个白痴，应该早点得到这个。

#!/bin/bash

workingdirs=`ls ~/ | grep -viE "temp1|temp2|temp3"`

if [ -d "$workingdirs" ]
then
echo "nothing new"

else

echo "The following Direcetories are now present"
echo ""
echo "$workingdirs"

fi

Answer 1

如果要在创建新目录时执行某些操作，请使用inotifywait。如果您只是想检查存在的目录是否是您期望的目录，您可以执行以下操作：

trap 'rm -f $TMPDIR/manifest' 0

# Create the expected values.  Really, you should hand edit
# the manifest, but this is just for demonstration.
find "$Workingdir" -maxdepth 1 -type d > $TMPDIR/manifest

while true; do
    sleep 60 # Check every 60 seconds.  Modify period as needed, or
             # (recommended) use inotifywait
    if ! find "$Workingdir" -maxdepth 1 -type d | cmp - $TMPDIR/manifest; then
        : Unexpected directories exist or have been removed
    fi
done

Answer 2

下面的shell脚本将显示目录是否存在。

#!/bin/bash

Workingdir=/root/working/
knowndir1=/root/working/temp1
knowndir2=/root/working/temp2
knowndir3=/root/working/temp3
my=/home/learning/perl

arr=($Workingdir $knowndir1 $knowndir2 $knowndir3 $my) #creating an array

for i in ${arr[@]}     #checking for each element in array
do
        if [ -d $i ]
        then
        echo "directory $i present"
        else
        echo "directory $i not present"
        fi
done

输出：

directory /root/working/ not present
directory /root/working/temp1 not present
directory /root/working/temp2 not present
directory /root/working/temp3 not present
**directory /home/learning/perl present**

这会将列表中的可用目录保存到文件中。第二次运行脚本时，它将报告已删除或添加的目录。

#!/bin/sh

dirlist="$HOME/dirlist"  # dir list file for saving state between runs
topdir='/some/path'      # the directory you want to keep track of

tmpfile=$(mktemp)

find "$topdir" -type d -print | sort -o "$tmpfile"

if [ -f "$dirlist" ] && ! cmp -s "$dirlist" "$tmpfile"; then
    echo 'Directories added:'
    comm -1 -3 "$dirlist" "$tmpfile"

    echo 'Directories removed:'
    comm -2 -3 "$dirlist" "$tmpfile"
else
    echo 'No changes'
fi

mv "$tmpfile" "$dirlist"

对于具有非常奇特的名称（包含换行符）的目录，脚本会出现问题。

bash检查目录下的子目录
