sudo:無法執行 ./script.sh:沒有這樣的文件或目錄

  • January 20, 2021

我難住了。我的/home目錄中有一個可執行的腳本:

[user@server ~]$ ll
total 4
-rwx------ 1 user user 2608 Jul 15 18:23 qa.sh

但是,當我嘗試使用它執行它時sudo說它找不到它:

[user@server ~]$ sudo ./qa.sh 
[sudo] password for user: 
sudo: unable to execute ./qa.sh: No such file or directory

這是一個全新的版本。沒有進行任何會導致問題的更改。事實上,腳本的重點是確保它實際上是根據我們的策略建構的。也許它不是並且sudo實際上在建構過程中被破壞了?

我還應該注意,我可以sudo在其他目錄中使用其他命令執行。

編輯:腳本(我沒有寫,所以請不要/bin/bash讓我超過它;))

這通常發生在#!腳本中的 shebang ( ) 行損壞時。

shebang 告訴核心文件需要使用解釋器執行。不帶 執行時sudo,消息更有意義。但隨著sudo你得到你得到的資訊。

例如:

$ cat test.sh
#!/bin/foo
echo bar

$ ./test.sh
bash: ./test.sh: /bin/foo: bad interpreter: No such file or directory

$ bash test.sh
bar

$ sudo ./test.sh
sudo: unable to execute ./test.sh: No such file or directory

$ sudo bash ./test.sh
bar

bad interpreter消息清楚地表明這是有問題的shebang。
