- `dviconcat -m 1000 file1 file2 ...` — set magnification of output

## Name

dviconcat — concatenate DVI files

## Synopsis

`dviconcat` [ `-m` *magnification* ] [ `-o` *outfile* ] *list of files*

## Options

- `-m *magnification*` — set the magnification of the output file. If not specified, the magnification of the first input file is used. A warning is issued if the magnification is changed.
- `-o *outfile*` — write output to *outfile* instead of standard output.

## Description

`dviconcat` concatenates the named DVI files (or standard input if no files are given) and writes the result to standard output (or to the file specified by `-o`). The output is a valid DVI file usable by TeX conversion programs or by `dviconcat` itself.
