在android模拟器环境中从字符串中提取单个字段

我正在使用adbshell运行 android 模拟器

我尝试从查询输出中提取该字段。_id=number

  • “原始”结果如下所示： 
    Row: 9991 last_time_contacted=0, phonetic_name=NULL, custom_ringtone=NULL, contact_status_ts=NULL, pinned=0, photo_id=NULL, photo_file_id=NULL, contact_status_res_package=NULL, contact_chat_capability=NULL, contact_status_icon=NULL, display_name_alt=+90532555688, sort_key_alt=+90532555688, in_visible_group=1, starred=0, contact_status_label=NULL, phonebook_label=#, is_user_profile=0, has_phone_number=1, display_name_source=40, phonetic_name_style=0, send_to_voicemail=0, lookup=0r10070-24121C1814241820221C1A14.3789r10071-24121C1814241820221C1A14.0r10072-24121C1814241820221C1A14.0r10073-24121C1814241820221C1A14.0r10074-24121C1814241820221C1A14.0r10075-24121C1814241820221C1A14.0r10078-24121C1814241820221C1A14.0r10082-24121C1814241820221C1A14.0r10083-24121C1814241820221C1A14.0r10084-24121C1814241820221C1A14.0r10085-24121C1814241820221C1A14.0r10086-24121C1814241820221C1A14.0r10087-24121C1814241820221C1A14.0r10092-24121C1814241820221C1A14.0r10094-24121C1814241820221C1A14.0r10097-24121C1814241820221C1A14, phonebook_label_alt=#, contact_last_updated_timestamp=1612984348874, photo_uri=NULL, phonebook_bucket=213, contact_status=NULL, display_name=+90532555688, sort_key=+90532555688, photo_thumb_uri=NULL, contact_presence=NULL, in_default_directory=1, times_contacted=0, _id=10097, name_raw_contact_id=10070, phonebook_bucket_alt=213
  • 我想_id=10097从上面的输出中提取字符串。
  • 到目前为止我的尝试： 
    content query --uri content://com.android.contacts/contacts | grep "+9053158888" |   awk -F'[,,= ]' '{cmd="content delete --uri content://com.android.contacts/contacts/"$(NF-3);system(cmd)}'

但它找不到该字符串。

答案1

便携式解决方案：

$ grep -o "[[:blank:]]\+_id=[^,]*" | sed 's/^ //'
_id=10097

如果你有GNU grep可用，与lookbehind assertion:

$ grep -Po "(?<=[^a-z])_id=[^,]*"
_id=10097
