我在做什麼錯誤，我的循環正在處理整個目錄列表，而不是每個單獨的文件名？

Question

我已經編寫了一個腳本，將從Dropbox中獲取種子文件，將它們添加到傳輸並將該種子移動到另一個位置。腳本正在爲我工​​作，只要我一次只將一個文件放在一個文件夾中。如果我在文件夾中有多個文件，它會給我一個關於文件路徑太長的錯誤。任何人都可以從我的腳本中知道我做錯了什麼，以及如何改變它，以便它可以正確處理多個文件？這是Mac上的bash腳本，通過launchd每60秒執行一次。

謝謝！

你做錯了什麼是trying to parse ls而不是使用glob表達式。

shopt -s nullglob # make globs return empty set on failure to match 
for torrent in "$WATCH_PATH/$wf"/*torrent*; do 
    echo "Found $torrent" 
done 

---

...或者，存儲水珠導致數組：

shopt -s nullglob # can just put this once at the top of your script 
wf_list=("$WATCH_PATH/$wf/"*torrent*) 
echo "Found ${#wf_list[@]} torrents:" 
for torrent in "${wf_list[@]}"; do 
    printf '- %q\n' "$torrent" 
done 

---

如果你把引號關 - for torrent in $WF_LIST - 這將使字符串分裂並在ls的輸出上進行glob擴展，但是這本身就是bug（用空格打破文件名，破壞可以被解釋爲glob擴展的文件名等）。不要這樣做。
