如何将 txt 文件从 samba-tool 转换为 bash 脚本中的 json 文件

Question

首先我想写的是我正在学习编写脚本。我在 Ubuntu 22.04 ADDC Samba 上设置的 VBox 中有一个测试域“universum.local”。我想使用 bash 脚本查询域控制器以获取域用户列表 (10)，并将有关它们的数据保存到 json 文件中。目前我能够获取必要的信息并将其保存到 txt 文件中。

这是我的脚本代码：

#!/bin/bash
clear

ldapuserslistfilename="ldapuserslist.txt"
ldapuserslistfile="$tmp/$ldapuserslistfilename"
    
ldapusersinfofilename="ldapusersinfo.txt"
ldapusersinfofile="$tmp/$ldapusersinfofilename"

# main code
touch $ldapuserslistfile
touch $ldapusersinfofile

samba-tool user list > $ldapuserslistfile

while read -r line ; do
 for user in $line ; do
  samba-tool user show $user >> $ldapusersinfofile
 done
done < $ldapuserslistfile

# copying txt files for tests
cp $ldapuserslistfile /mnt
cp $ldapusersinfofile /mnt

# deleting files
if [ -f $ldapuserslistfile ] ; then rm -f $ldapuserslisfile ; fi
if [ -f $ldapusersinfofile ] ; then rm -f $ldapusersinfofile ; fi

有输出，所有用户都保存在txt文件中，格式如下：

dn: CN=Bruce Banner,OU=Users,OU=MARVEL,OU=UNIVERSUM,DC=universum,DC=local
objectClass: top
objectClass: person
objectClass: organizationalPerson
objectClass: user
cn: Bruce Banner
sn: Banner

memberOf: CN=Avengers,OU=Groups,OU=MARVEL,OU=UNIVERSUM,DC=universum,DC=local
distinguishedName: CN=Bruce Banner,OU=Users,OU=MARVEL,OU=UNIVERSUM,DC=universum,DC=local

我想要 json 格式的数据，例如

{
  "users": [
            {
             "cn" : "Bruce Banner",
             "sn" : "Banner",
             "givenName" : "Bruce",
             "whenCreated" : "20220926075536.0Z",
             "<objectname>" : "<value>",
             "<objectname>" : "<value>",
            },
            {
             <next user info>
            },
            {
             <next user info>
            }
           ]
}

objectname 是下一个用户项，如lastLogon、lastLogoff 等。我想将所有用户保存在json 文件中，以便我可以使用计算机上的另一个powershell 脚本读取它们

更新：

我添加了下面几行

# conversion fron txt to json
jsonfilename="jsontestfile.json"
json="./$jsonfilename"
touch $json

ed -s $ldapusersinfofile  << 'EOF' > $json
v/^cn:\|^sn:\|^givenName:\|^displayName:\|^name:\|^whenCreated:/d
,s/^\(.*[^:]*\): \(.*\)/"\1": "\2"/
g/cn\|sn\|givenName\|displayName\|name\|whenCreated/s/$/,/
,s/^/   /
g/lastLogon/t. \
s/.*/},/g
1,$-1g/}/t. \
s/.*/{/g
0a
{
.
$s/,//
,p
Q
EOF

在#main代码部分和#copying txt文件进行测试部分之间，我已经输出到json文件，如

{
   "cn": "James Rhodes",
   "sn": "Rhodes",
   "givenName": "James",
   "whenCreated": "20220926075852.0Z",
   "displayName": "James Rhodes",
   "name": "James Rhodes",
   "lastLogon": "0"
},
{
   "cn": "T'Chala",
   "givenName": "T'Chala",
   "whenCreated": "20220926081521.0Z",
   "displayName": "T'Chala",
   "name": "T'Chala",
   "lastLogon": "0"
},
{
   "cn": "Stephen Strange",
   "sn": "Strange",
   "givenName": "Stephen",
   "whenCreated": "20220926080942.0Z",
   "displayName": "Stephen Strange",
   "name": "Stephen Strange",
   "lastLogon": "0"
}

为了能够读取我的 powershells 脚本中的 json 文件，缺少

    {
        "users": [

在开始数据和

      ]
    }

在数据末尾有类似的文件

{
    "users": [
                   {
                    "cn": "James Rhodes",
                    "sn": "Rhodes",
                    "givenName": "James",
                    "whenCreated": "20220926075852.0Z",
                    "displayName": "James Rhodes",
                    "name": "James Rhodes",
                    "lastLogon": "0"
                   },
                   {
                    "cn": "T'Chala",
                    "givenName": "T'Chala",
                    "whenCreated": "20220926081521.0Z",
                    "displayName": "T'Chala",
                    "name": "T'Chala",
                    "lastLogon": "0"
                   },
                   {
                    "cn": "Stephen Strange",
                    "sn": "Strange",
                    "givenName": "Stephen",
                    "whenCreated": "20220926080942.0Z",
                    "displayName": "Stephen Strange",
                    "name": "Stephen Strange",
                    "lastLogon": "0"
                   }
               ]
}

通过PS脚本阅读

Clear
$json = Get-Content <pathToFile>\jsontestfile.json -Raw | ConvertFrom-Json

foreach ($user in $json.users){
 echo $user.cn
 echo $user.sn
 echo $user.givenName
 echo "----------"
}

如何添加缺失的字符？

Answer 1

您需要“jq”，然后解析 samba-tool 的输出，如下所示：

sudo samba-tool user show $USERNAME -H ldap://<DC_SHORT_HOSTNAME> -d0 | jq -R -s -c 'split("\n")'

您可以轻松地在用户名列表中使用“for 循环”。

Answer 2

我将代码更改为：

# add prefix
printf '{\n"users" :\n[\n' > $json
# add converted users data
ed -s $data << 'EOF' >> $json
v/^cn:\|^sn:\|^givenName:\|^whenCreated:\|^displayName:\|^name:\|^badPwdCount:\|^badPasswordTime:\|^lastLogoff:\|^primaryGroupID:\|^accountExpires:\|^sAMAccountName:\|^userPrincipalName:\|^pwdLastSet:\|^userAccountControl:\|^lastLogonTimestamp:\|^whenChanged:\|^lastLogon:\|^logonCount:\|^distinguishedName:/d
,s/^\(.*[^:]*\): \(.*\)/"\1" : "\2"/
g/cn\|sn\|givenName\|whenCreated\|displayName\|name\|badPwdCount\|badPasswordTime\|lastLogoff\|primaryGroupID\|accountExpires\|sAMAccountName\|userPrincipalName\|pwdLastSet\|userAccountControl\|lastLogonTimestamp\|whenChanged\|lastLogon\|logonCount/s/$/,/
,s/^/  /
g/distinguishedName/t. \
s/.*/},/g
1,$-1g/}/t. \
s/.*/{/g
0a
{
.
$s/,//
,p
Q
EOF
# add suffix
printf ']\n}' >> $json

现在可以使用了，Powershell 可以读取我的文件。
