Bin Bash Terminal腳本使用Mac SIPS調整PNG / CR2 / JPG圖像的大小並節省空間

Question

我編寫了一個很棒的小腳本，將我的JPG / PNG / CR2（原始文件）的大量照片集轉換為2880px JPEG的MacBook Pro Retina分辨率。

這使我可以將所有照片保存在計算機上，同時將巨型原件存儲在外部硬盤驅動器上。 所有圖片中最好的一張看起來很棒，因為它們被調整為我確切的物理屏幕分辨率，寬度為2880px！

您可以輕松地根據自己的需要調整腳本...

好，繼續我的問題。

我在外部硬盤驅動器上的圖片存儲如下：

（硬盤根）

圖片

2013-05佛蒙特州婚禮

img_0001.jpg

img_0002.jpg

2014-10拉斯維加斯之旅

img_0001.cr2

img_0002.cr2

...

現在，腳本覆蓋了原始文件...因此，我始終需要將所有圖片的完整副本復制到第二驅動器，然后運行腳本。 有沒有一種簡單的方法可以使腳本重新創建整個目錄結構，並將新文件寫出到新的文件夾/驅動器中，同時保持目錄結構？

謝謝你的幫助！

感謝您的幫助Mark Setchell！

Answer 2

當然。 在頂部的腳本中設置一個變量，或者傳入一個新參數，該參數說明要在何處創建新的樹結構。 或混合使用，並設置默認的新根目錄，但允許用戶在命令行上使用第二個參數覆蓋它，如下所示：

newroot=${2:-~/Desktop/resized}

然后使用dirname獲取每個輸入圖像所在的目錄的名稱，如下所示：

dir=$(dirname "/users/bozo/tmp/image.jpg")

那會給你

/users/bozo/tmp

現在將新目錄路徑放在最前面

newpath="$newroot/$dir"

並做到這一點，包括所有中間文件夾，並忽略與

mkdir -p "$newpath" 2> /dev/null

然后將命令更改為這樣輸出

 file=$(basename "input image path")
 sips ... --out "$newpath/$file"
