シェルの実行権限

./test.sh

#!/bin/sh
echo "Hello, World!"

[vagrant@localhost test]$ sed ‘s/\r//’ test.sh
#!/bin/sh
echo “Hello, World!”[vagrant@localhost test]$ ./test.sh
-bash: ./test.sh: 許可がありません
[vagrant@localhost test]$ ls -l
合計 8
-rw-rw-r– 1 vagrant vagrant 219 3月 31 16:33 2019 index.php
-rw-rw-r– 1 vagrant vagrant 31 4月 1 20:34 2019 test.sh

パーミッションは664。644に変えてみる。

[vagrant@localhost test]$ chmod 644 test.sh
[vagrant@localhost test]$ ./test.sh
-bash: ./test.sh: 許可がありません

やっぱり755でないと駄目なのか。。
モード(数字)｜モード(アルファベット)｜権限
4｜r｜読み取り
2｜w｜書き込み
1｜x｜実行

chmod +x というのは、実行権限を与える、ということね。

[vagrant@localhost test]$ chmod u+x test.sh
[vagrant@localhost test]$ ./test.sh
Hello, World!
[vagrant@localhost test]$ chmod u-x test.sh
[vagrant@localhost test]$ ./test.sh
-bash: ./test.sh: 許可がありません

なるほど、実行権限か～
