How to Force Cp to Overwrite Without Confirmation

How to force cp to overwrite without confirmation

You can do yes | cp -rf xxx yyy, but my gutfeeling says that if you do it as root - your .bashrc or .profile has an alias of cp to cp -i, most modern systems (primarily RH-derivatives) do that to root profiles.

You can check existing aliases by running alias at the command prompt, or which cp to check aliases only for cp.

If you do have an alias defined, running unalias cp will abolish that for the current session, otherwise you can just remove it from your shell profile.

You can temporarily bypass an alias and use the non-aliased version of a command by prefixing it with \, e.g. \cp whatever

Force cp to overwrite when -i option used by defaul

You have two possibilities:

First uses system cp instead of invoking your alias:

/bin/cp .....

Second overrides -i option (so it looks like cp -i -n instead)

cp -n ....

The second one is much less readable so I suggest using the first one.

How to specify the files to overwrite using linux cp command on PHP?

XCOPY: Overwrite all without prompt in BATCH

How to remove double quotes without escape (^) in cmd/ batchfile?

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.
