unidentified characters in terminal window (myname@boss-пк)

Assuming your Mac's name is correctly shown in System Preferences > Sharing, it is possible you inadvertently changed the default Terminal prompt.

• Hi everyone,

While using a terminal today I noticed strange characters after my computer name on the terminal. What does it mean? How can I get rid of it?

it is a default window of the terminal.

Doesn't mean much...just depends on what you want to see.

Return the default prompt (note the trailing empty space) copy & paste:

export PS1="%n@%m %1~ %# " 

ex. username@MacBook-Pro ~ %

You can customize the prompt...

changed this with:

export PS1="%m %1~ %# " 

ex. MacBook-Pro ~ %
