@sea: note that ${line:0:3} is bash syntax (or ksh93 or zsh), so the script should be called with bash, rather than sh. Even though on some systems sh is a link to bash, which will result in calling bash with the --posix option, there are many systems where this is not the case and so there the script would fail if called this way.

untex

UNTEX(1)						      General Commands Manual							  UNTEX(1)

NAME

       untex - strip LaTeX comands from input

SYNOPSIS

       untex [ options ] [ files ...  ]

DESCRIPTION

       Untex removes some LaTeX commands from the files listed in the arguments (or standard input) and prints the output to standard output.

OPTIONS

       -      read from standard input.

       -o     remove options to LaTeX commands, i. e. everything in brackets [] behind a command.

       -i     process "include{file}" and "input{file}" and "input file" commands.

       -m     (try to) remove all math code.

       -u     replace all "a (etc.) with ibm (CP850) characters.

       -uiso  replace all "a (etc.) with ISO characters.

       -uascii
	      replace all "a (etc.) with ascii characters.

       -g     replace all "a (etc., from german.sty) with ibm (CP850) characters.

       -giso  replace all "a (etc., from german.sty) with ISO characters.

       -gascii
	      replace all "a (etc., from german.sty) with ascii characters.

       -e     remove environment names.

       -a     remove arguments of commands (not recommended).

       -g implies -u, -a implies -o.

SEE ALSO

       latex, tex, detex

BUGS

       The  -g	and  -u options only work for german accented characters. Not fixed due to lack of time, any help is appreciated. The includeonly
       command is ignored.

       Using -u option in a UTF-8 terminal doesn't work. Using it alone in a Latin1 terminal doesn't work either, you must also add -uiso.

AUTHORS

       Untex was written by Michael Staats (michael@hal6000.thp.Uni-Duisburg.DE). The -gascii and -uascii options  were  added	by  Denis  Endisch
       (denis@smoky.ikf.physik.uni-frankfurt.de).   Thanks to Subhasish Mazumdar (mazumdar@ringer.cs.utsa.edu) for some hints for improvements and
       bug reports.
