# 找出 Downloads 中超過 30 天的檔案，並移至 Trash
find ~/Downloads/ -maxdepth 1 -mtime +30 | xargs -i mv {} ~/.local/share/Trash/files/
# 您可以使用以下指令來找出路徑中的大檔案列表：
find /path/to/directory -type f -size +100M -exec ls -lh {} \;
# 這個指令將在指定的目錄中尋找大小大於 100MB 的檔案，並列出檔案的詳細資訊。
# 您可以根據需要調整 `-size +100M` 的數值，以符合您的搜尋條件。

### 找出所有以 git 開頭的檔案所屬的資料夾：
```
find /path/to/directory -type f -name "git*" -exec dirname {} \; | sort | uniq
```
在上述的指令中，-exec dirname {} \; 是用來執行一個指令的功能，{} 代表先前找到的每個檔案的路徑。在這個情況下，dirname {} 會取得每個檔案的路徑，並輸出它的目錄部分。
這樣做的目的是為了將找到的檔案的路徑轉換成目錄的路徑，以便後續的 sort 與 uniq 指令可以正確地對它們進行排序與去重複操作。透過 -exec dirname {} \; 的使用，我們能夠在同一條指令中取得檔案的目錄路徑，並且為它們做進一步的處理。
