居然说 echo: command not found

[cyl-seaside]

#!/bin/bash
if [ "$SHELL" = "/bin/bash" ]; then
　echo "your login shell is the bash (bourne again shell)"
else
　echo "your login shell is not bash but $SHELL"
fi

我在运行上面个脚本的时候，居然说这样說
怎么回事呐

[sinyadvan]

把echo前的全角空格删了

[cyl-seaside]

不行啊

#!/bin/bash
if [ "$SHELL" = "/bin/bash" ]; then
　echo"your login shell is the bash (bourne again shell)"
else
　echo"your login shell is not bash but $SHELL"
fi

./b: line 3: 　echoyour login shell is the bash (bourne again shell): command not found

恩，看到楼主的改写后的脚本我觉得还是去河边看别人钓鱼吧。。。

echoyour login
echo后面要加空格的吧
echo"test"报错，
echo "test"没错

[cyl-seaside]

#!/bin/bash
echo "hello"

呵呵，这个就行

[cyl-seaside]

额，是这样的啊

#!/bin/bash
if [ "$SHELL" = "/bin/bash" ]; then
echo "your login shell is the bash (bourne again shell)"
else
echo "your login shell is not bash but $SHELL"
fi

[BigSnake.NET]

不行啊

#!/bin/bash
if [ "$SHELL" = "/bin/bash" ]; then
　echo"your login shell is the bash (bourne again shell)"
else
　echo"your login shell is not bash but $SHELL"
fi

./b: line 3: 　echoyour login shell is the bash (bourne again shell): command not found

前后有歧义
