I am unable to type (Control A) characters in a shell script. By using (Ctrl+V) and then (Ctrl+A). I am unable to do so. I am able to give (Ctrl+A) from cli but not in a shell script. I am typing the shell script in vi.

What I am trying to do is write a shell script containing the command sed 's/^A//g', i.e. trying to replace (Ctrl+A) with NULL.

@Joy，如果您使用的是 Vi/Vim，请确保您处于插入模式，然后按 (Ctrl+V)，然后按 (Ctrl+A) 输入 ^A。抱歉，我真的不明白为什么这不起作用...也许您的 (Ctrl+V) 按键被其他软件层捕获？

这对我有用：

cat file
This is a test ^A more data

sed 's/\^A//g' file
This is a test  more data
