I know little about shell script,so I don't know how to fix it.I hope some one here could help me .Thanks alot.
I put the origin file here as well

echo The shell script \'virtualtex\' is a tool for Celestia \> 1.3.0
echo that supports \'virtual textures\'.
echo
echo The script generates the required tiles tx_i_j of \
desired \(square\) size,
echo \<tile size\>, in a specified format, \<tile format\> = \
png, tga, jpg,...,
echo from an input texture, \<texture name\>, in any popular graphics format.
echo
echo The optional 4th argument e\|E\|w\|W is for the case of tiling
echo square /e/astern \| /w/estern halfes of the full texture separately!
echo
echo Besides Linux/Unix, the script also runs in a current Cygwin \
installation
echo under Windows, \( http://www.cygwin.com \). If the z-shell \(\'zsh\'\) \
is unavailable,
echo it also may be executed with the \'bash\' shell, by replacing \
\#\! /usr/bin/zsh by
echo \#\! /bin/bash in the first line.
echo
echo The script assumes that a recent version of the ImageMagick package
echo \( http://www.ImageMagick.org \) is installed \
\(either under Unix/Linux or Windows\).
echo The utilities \'convert\' and \'identify\' of that package are used.
echo
echo You may increase the pixel cache size \$maxmem from the 80 MB default
echo value to e.g. 80\% of your RAM size within the script with an editor.
echo This will speed up the performance of \'virtualtex\' considerably.
echo
echo On a PIII/512MB RAM the tiling of a 16k x 8k texture into
echo 32 \(2k x 2k\) tiles now only takes 15 minutes with a Linux OS!
