STDIN and STDOUT

Hallo,

i have a script like:

PHP Code:
if [$1] ;then
echo "OK"

else 
echo 
"ERROR $2 is missing"

fi;

if [$
2];then
touch 
$2

fi
;

if [$
2];then
 cat 
$1  grep xy > $2

fi

but i must do that with STDIN and STDOUT, when i want to run the script it must not give parameters. It must run like
PHP Code:
cat zz | ./rrr.sh zz_solution.txt

NAME
fastq_quality_trimmer - Filters sequences based on quality DESCRIPTION
usage: fastq_quality_trimmer [-h] [-v] [-t N] [-l N] [-z] [-i INFILE] [-o OUTFILE] Part of FASTX Toolkit 0.0.13.1 by A. Gordon (gor- don@cshl.edu) [-h] = This helpful help screen. [-t N] = Quality threshold - nucleotides with lower quality will be trimmed (from the end of the sequence). [-l N] = Minimum length - sequences shorter than this (after trimming) will be discarded. Default = 0 = no minimum length. [-z] = Compress output with GZIP. [-i INFILE] = FASTQ input file. default is STDIN. [-o OUTFILE] = FASTQ output file. default is STDOUT. [-v] = Verbose - report number of sequences. If [-o] is specified, report will be printed to STDOUT. If [-o] is not specified (and output goes to STDOUT), report will be printed to STDERR. SEE ALSO
The quality of this automatically generated manpage might be insufficient. It is suggested to visit http://hannonlab.cshl.edu/fastx_toolkit/commandline.html to get a better layout as well as an overview about connected FASTX tools. fastq_quality_trimmer 0.0.13.1 April 2012 FASTQ_QUALITY_TRIMMER(1)
