latex2e: Command line

 
 26 Command line
 ***************
 
 The input file specification indicates the file to be formatted; TeX
 uses '.tex' as a default file extension.  If you omit the input file
 entirely, TeX accepts input from the terminal.  You can also specify
 arbitrary LaTeX input by starting with a backslash.  For example, this
 processes 'foo.tex' without pausing after every error:
 
      latex '\nonstopmode\input foo.tex'
 
    With many, but not all, implementations, command-line options can
 also be specified in the usual Unix way, starting with '-' or '--'.  For
 a list of those options, try 'latex --help'.
 
    If LaTeX stops in the middle of the document and gives you a '*'
 prompt, it is waiting for input.  You can type '\stop' (and return) and
 it will prematurely end the document.
