When I was exporting data today, I encountered an error code : "EXP-00056: ORACLE error 12154 encountered" because the password of the user name uses special characters. To find the reason online, it needs to be expanded with quotation marks, but the os is different. , the way is also different:
windows os: exp username/"""password"""@devdb --3 double quotes to expand the password
linux/unix os: exp 'username/"password"@devdb' -- 1 double quote to expand the password, 1 single quote to expand the whole
