# update-latex-ucs(8)

Regenerate latex-ucs data directory

## NAME

update-latex-ucs - Regenerate latex-ucs data directory

## SYNOPSIS

**update-latex-ucs** \[ **-b** \] \[ **-c** \]\
 **update-latex-ucs -h**

## DESCRIPTION

**update-latex-ucs** regenerates the data directory of latex-ucs (/usr/share/texmf/tex/latex/ucs/data) from the glyph sources (\*.ucf, \*.ucf.gz) in /usr/share/latex-ucs-dev/config. It does so by calling the script makeunidef.pl ( (c) 2003 Dominique Unruh) with appropriate parameters.

Before the generation process, the original data directory is renamed to data.old, for the case that anything goes wrong. After a successful generation process you may safely delete the data.old directory to save some space.

After a successful generation process, mktexlsr is called to rebuild LaTeX's file hash.

## OPTIONS

This program follows the usual GNU command line syntax, with long options starting with two dashes (\`-').

- **-c, --comments**

  Generate data files with comments (default is no comments). This option is simply passed to makeunidef.pl.

- **-b, --nobackup**

  Do not backup the original data directory before the generation.

- **-h, --help**

  Print a small help message.
