linux - Shell 命令不适用于 TinyPNG 的压缩照片

Question

大家好，我对 shell 了解不多。我需要压缩一些 PNG 文件，我在 web 上找到了一个 bash shell 脚本. bash shell 通常与 tinyPNG 的 API 一起工作。

当我运行 shell 时出现此错误:

bash: tinypng.sh: command not found...

我试过用这个方法运行它:

tinypng.sh  -d [DIRECTORY]/

我也试过这样做:

bash tinypng.sh  -d [DIRECTORY]/

当我运行时，我只是这个信息:

NAME tinypng - Shrink PNGs using tinypng.com service.

SYNOPSIS tinypng [-dkph] -f FILE

DESCRIPTION Shrink PNGs using tinypng.com service.

On first execution, or if /DIRECTORY/DIRECTORY/.tinypng.apikey is not present, tinypng will ask for an API key.

Obtain your API key from https://tinypng.com/developers, copy and paste it when prompted.

OPTIONS

-f,--file FILE              Select a FILE to be shrinked.
    -d,--download DIRECTORY     Download all shrinked PNGs to DIRECTORY.
    -k,--key API_KEY            Use API_KEY, instead of the one stored in /DIRECTORY/DIRECTORY/.tinypng.apikey.         -p,--print                  When -d is being used, the URLs of the shrinked PNGs are not being printed to stdout.                                     Use this option to force printing even when using -d.
                                Otherwise, this option is set implicitly.
    -- FILES                    Ignore any options to come.
                                Everything after this option is considered a file.
    -h,--help                   Show this message and exit successfully.
         EXAMPLES
   Shrink foo.png, bar.png, baz.png and print the result URLs to stdout.
     $ tinypng -f foo.png -f bar.png -f baz.png
         or
     $ tinypng -- foo.png bar.png baz.png
     Shrink foo.png, bar.png, baz.png and download the result PNGs to tiny_pngs/ directory
    $ tinypng -d tiny_pngs/ -- foo.png bar.png baz.png

tinypng --help 显示您的解决方案:

tinypng -d tiny_pngs/-- foo.jpg bar.png baz.png

这将缩小 foo.jpg、bar.png、baz.png 并将缩小的文件下载到 tiny_pngs/目录。
