tcmts.studio.updateScratch · #xso7d43c · term · runs on the server

uses node:fs

Update the codebase with the scratch file file (holding text), as tcm update <file> --clear does (a file kept as written, --into where it goes, unless it's Markdown, whose first line says): it's run, on the branch the studio serves, so what it does, refuses, and says is the command's, and the file goes once what it held is saved. What it said, and the history entry it made.
