是否有任何方法仅通过任何方法过滤.png文件？

Question

我有几行代码，我只想过滤不同名称的.png文件。例如，我有这样的代码，如下所示。现在，我只想过滤具有.png扩展名的文件名，我想要的结果如下所示。

任何一种方法都值得赞赏，我正在拼命地研究这个解决方案，但没有找到完美的方法来实现它。

我想要的结果：

game/objects/rock_2_shadow.png，game/objects/stump_shadow.png，game/objects/tv.__png等等..。

这是代码：

{ bytes: 4531, md5: "DLKvNDSl0Q3y0tlFGNol_A", name: "game/objects/rock_2.png" }, { bytes: 4208, md5: "z1v6RXDu0F6WXFyyBGsBKg", name: "game/objects/rock_2.webp" }, { bytes: 741, md5: "DlK9Ugd6e5L-99V-ryGoiA", name: "game/objects/rock_2_shadow.png" }, { bytes: 448, md5: "e68ha5bvslyYsG_8Kr1dtQ", name: "game/objects/rock_2_shadow.webp" }, { bytes: 3125, md5: "t3eBjoR_9QzrRMgJzlgWCA", name: "game/objects/rock_3.png" }, { bytes: 2670, md5: "z_w1xtubTBXfp0DHun_pHQ", name: "game/objects/rock_3.webp" }, { bytes: 618, md5: "c-l97Wj4nZySEnf2XBAt1Q", name: "game/objects/rock_3_shadow.png" },

                        { bytes: 980, md5: "ipcG0uMYI9BG8FM8fK6k_Q", name: "game/objects/stump_shadow.png" }, { bytes: 666, md5: "fkLA18GD8gItBTbOVJnPog", name: "game/objects/stump_shadow.webp" }, { bytes: 13840, md5: "v6Nxnc6mADteI8cxC_GPiA", name: "game/objects/table.png" }, { bytes: 13144, md5: "xiMMaXe48fR5QLQ0DCD2qw", name: "game/objects/table.webp" }, { bytes: 1556, md5: "FVUAV5dhR4uwaCNkfgkQJg", name: "game/objects/table_shadow.png" }, { bytes: 1092, md5: "XLhQsppcDFFPlADxuhATEw", name: "game/objects/table_shadow.webp" }, {
                            name: "game/objects/tv.png"

Answer 1

它非常难看，但是如果您将所有数据放入一个名为data.json的文件中，您可以运行以下杀死程序：

linefeeds

• looks

• 将字符串name:

• prints的所有逗号转换为，不管后面是双引号

tr , '\n' < data.json | awk -F'"' '/name:/{print $2 }'

game/objects/rock_2.png
game/objects/rock_2.webp
game/objects/rock_2_shadow.png
game/objects/rock_2_shadow.webp
game/objects/rock_3.png
game/objects/rock_3.webp
game/objects/rock_3_shadow.png
game/objects/rock_3_shadow.webp
game/objects/rock_4.png
game/objects/rock_4.webp
game/objects/rock_4_shadow.png
game/objects/rock_4_shadow.webp
game/objects/stump.png
game/objects/stump.webp
game/objects/stump_shadow.png
game/objects/stump_shadow.webp
game/objects/table.png
game/objects/table.webp
game/objects/table_shadow.png
game/objects/table_shadow.webp
game/objects/tv.png

您可以为png添加一个额外的过滤器。

你可能会发现这更简单。它将所有双引号音译为换行符，并查找以.png结尾的行。

tr '"' '\n' < data.json | grep "\.png$"

如果数据存储在名为data的data变量中，而不是存储在名为data.json的文件中，则只需使用以下语法：

echo "$data" | tr '"' '\n' | grep "\.png$"

Answer 2

grep -Eo '[0-9a-z_/]+\.png' your_file.txt 

或

printf 'paste your code here' | grep -Eo '[0-9a-z_/]+\.png' 

输出：

game/objects/rock_2.png
game/objects/rock_2_shadow.png
game/objects/rock_3.png
game/objects/rock_3_shadow.png
game/objects/rock_4.png
game/objects/rock_4_shadow.png
game/objects/stump.png
game/objects/stump_shadow.png
game/objects/table.png
game/objects/table_shadow.png
game/objects/tv.png
