How do I escape an exclamation mark in bash?
提问by iblue
Sometimes I feel the urge to put some more expressiveness in my git commit messages. Unfortunately bash does not seem to like this.
有时我会想在我的 git commit 消息中加入更多的表现力。不幸的是，bash 似乎不喜欢这样。
iblue@silence ~/git/wargames $ git commit -m "Frustrating <insert object of frustration here>!"
-bash: !": event not found
Escaping with a backslash helps, but this includes the backslash in the commit message.
使用反斜杠转义会有所帮助，但这包括提交消息中的反斜杠。

回答by sblom
Exclamation mark is preserved literally when you include it in a single-quoted string.
当您将感叹号包含在单引号字符串中时，它会按字面保留。
Example:
例子：
git commit -m 'Frustrating <insert object of frustration here>!'

Have a try this one
试试这个
git commit -m "Frustrating <insert object of frustration here>"'!'
git commit -m "Frustrating <insert object of frustration here>"'!'
If in the middle of string then
如果在字符串的中间然后
"hello"'!'"world"
"hello"'!'"world"

Use single quotes instead to prevent expansion.
请改用单引号以防止扩展。
