terminates a Wolfram Language kernel session.
- Quit quits only the Wolfram Language kernel, not the front end.
- To quit a notebook front end, choose the Quit menu item.
- All kernel definitions are lost when the kernel session terminates.
- If you have kept the definitions in a file or in a notebook you can always reenter them in a subsequent session.
- Quit can be used as a shortcut for Quit if it is the entirety of the input expression.
- Before terminating a kernel session, the Wolfram Language executes any delayed value that has been assigned to the global variable $Epilog. Conventionally, this attempts to read in, using Get, the package file end` that contains commands to be executed before termination.
- On most computer systems, Quit[n] terminates the Wolfram Language kernel, passing the integer n as an exit code to the operating system.
- On systems that support exit codes, Quit is equivalent to Quit.
- The Wolfram Language kernel uses the following exit codes when it quits automatically:
0 normal exit 1 an internal error occured 2 an attempt to start the kernel via WSTP failed 3 the kernel quit from the interrupt menu
- The Wolfram Language kernel uses exit codes between 60 and 85 when startup failed due to license restrictions. Most of these failures refer to a problem with a password entry found in $PasswordFile. Common values include:
60 the network license server cannot give licenses for this product 61 network license limit reached 62 invalid activation key/password combination 63 expired password 70 no password file found 71 unable to connect to network license server 72 password file empty 73 password file has empty password entry 74 password file has truncated password entry 75 network license server can only authorize older versions of the product 78 invalid activation key entered 81 the network license server instructed the kernel to terminate 82 the network license server refused to give a license 84 the network license server refused to give a license due to a configured restriction 85 single machine process limit reached
- Exit[…] is a synonym for Quit.
