linux檔案相關命令 透過檔案獲取父資料夾名稱

不說廢話, 先上命令

透過檔案獲取父資料夾名稱

dirname $(realpath `your_filename`)

---

透過檔案路徑得到檔名稱

basename `your_filename`

---

相關命令

basename

dirname

realpath

reallink

ls

pwd

---

透過檔案獲取父資料夾名稱

命令是這個:

dirname $(realpath `your_filename`)

為什麼需要這樣寫: 直接用dirname不行嗎? 請看示例:

aquawius@QU-openSuse-wsl ~/.c/fish> pwd
/home/aquawius/.config/fish

aquawius@QU-openSuse-wsl ~/.c/fish> ls
completions/  conf.d/  config.fish  fish_variables  functions/

aquawius@QU-openSuse-wsl ~/.c/fish> dirname .
.

aquawius@QU-openSuse-wsl ~/.c/fish> dirname config.fish
.

aquawius@QU-openSuse-wsl ~/.c/fish> realpath config.fish
/home/aquawius/.config/fish/config.fish

aquawius@QU-openSuse-wsl ~/.c/fish> dirname $(realpath config.fish)
/home/aquawius/.config/fish

似乎dirname需要得到一個絕對路徑的名稱才能得到這個檔案的父資料夾路徑. 將兩個命令合用即可.

basename `your_filename`

請看示例:

aquawius@QU-openSuse-wsl ~/.c/fish> basename ./config.fish
config.fish

aquawius@QU-openSuse-wsl ~/.c/fish> basename /home/aquawius/.config/fish/config.fish
config.fish
