如何使用awk
或获取特定数据sed
。我需要从哪里获取数据name="Admin_UserGroup"
?
编辑#1
谢谢侯赛因·瓦塔尼对于他的回答,以下是最终命令:
$ /opt/keycloak/bin/kcadm.sh get groups -r T0_Realm > Group.json
$ GROUP_ID_TEMP=$(grep -B1 -A0 '"name" : "Admin_UserGroup"' Group.json)
$ GROUP_ID=$(echo $GROUP_ID_TEMP | cut -d : -f2 | awk -F\" '{print $2}')
答案1
使用jq
:
$ printf '%s\n' "$Group_ID" | jq '.[] | select(.name == "Admin_UserGroup")'
{
"id": "89f3bd6a-33a9-4e02-9fe3-eae660c5a6cf",
"name": "Admin_UserGroup",
"path": "/Admin_UserGroup",
"subGroups": []
}
这将选择数组中name
键对应于 值的所有对象Admin_UserGroup
。
答案2
根据您对基本命令的考虑,如果您的文件具有与所示完全相同的结构,grep
可能会帮助您:
$ grep -B2 -A3 '"name" : "Admin_UserGroup"' File
但如果全部都在一行中:
$ sed -E 's/\},\s*\{/\},\n\{/g' File | grep '"name" : "Admin_UserGroup"'
使用您原来的示例,您可以像这样使用我的解决方案:
$ echo "$Group_ID" | grep ...

答案4
$ awk '{if($0~/"AdminUserGroup"/) {NR=NR-1;print $0; NR=NR+2;print $0; } }'file1
通过这种方式,我们可以打印搜索字符串附近的行信息。另外我认为我们可以将所有这些放入一个数组中,而不是打印它:
$ awk '{if($0~/"AdminUserGroup"/) {NR=NR-1;arr[$i]=(print $0);i=$((i+1)); \
NR=NR+2; arr[$i]=(print $0); } }'file1.
然后我们可以使用数组详细信息。
