如何在 cmd/批处理文件中删除不带转义 (^) 的双引号？

Question

Note: as the OP is a new user, I'm editing the question with reproducible details so that it doesn't get closed. It's a good question, but was originally confusing.

The Windows username is: jhon^smith

ECHO %username%
output : jhonsmith

My expectation:

jhon^smith

---

If I use:

echo "%username%"

then the output is:

"jhon^smith"

How can I remove the double quotes but keep the caret, which is actually part of the username?

Answer 1

This should work:

for /f %a in ("%username%") do echo %a

output:

jhon^smith

(btw: It should be spelt john^smith but never mind.)

Explanation:

In the command echo %username% , cmd.exe replaces %username% with its actual content, so the command becomes echo jhon^smith . This is then parsed, the the ^ is processed as the escape character, so it replaces ^s with s .

In the command for /f %a in ("%username%") do echo %a , the quoted string is treated as a string without the quotes, and no parsing of ^ is performed. Type for /? for more details.
