There, programmer Tim Paterson had developed a variant of CP/M-80, intended as an internal product for testing SCP's new 16-bit Intel 8086 CPU card for the S-100 bus. Gates in turn approached Seattle Computer Products.
SETX - Set an environment variable permanently.Įquivalent PowerShell: Create a function called Prompt (save in Profile.ps1 to make permanent).IBM again approached Bill Gates. “All actions are judged by the motive prompting them” ~ Muhammad Related commands If Command Extensions are disabled the commands $M and $+ are not supported.

Simulate an HP-UX style prompt with the computername and the current folder on separate the time, backspacing to hide the milliseconds: Examplesĭisplay the UNC path whenever you are using a network drive (mapped with NET USE) PROMPT does not error if passed invalid switches PROMPT /Z /invalid - it will just set them as part of the prompt. If an attempt is made to set a prompt using a dollar sign followed by any character not in the list of codes above, then everything after that dollar sign will be ignored. If prompt could not be changed %ERRORLEVEL% = 1 If the prompt was successfully changed %ERRORLEVEL% = unchanged, typically this will be 0 but if a previous command set an errorlevel, that will be preserved (this is a bug). When CMD Command Extensions are enabled (the default)
The dollar codes each count as 1 character. If a longer prompt is set it will be silently truncated to the first 511 symbols. The maximum length of a prompt string is 511 characters. The prompt variable only holds the prompt definition, the final prompt characters are calculated by the CMD console. To set the CMD prompt for all sessions, set a permanent environment variable ( SETX) with the appropriate prompt text. If the %PROMPT% variable is deleted, the prompt will automatically revert to the default. PROMPT $P$G is the same as SET PROMPT=$P$G) The PROMPT command is tied to the %PROMPT% environment variable, editing the variable will lead to the same result as using the PROMPT command (e.g.
