Data new bourne shell script

Hi mate,
I have modified my script , after your suggestion.

I guess the specific issue for me is the 'parameterization' of the shell script arguments thru a local variable 'index' .is there an alternative to this.

for example : how do i get the argument value of the 'n'th argument to the shell script .

can you address this problem .

Thanks
srinivas



set -x

tot_params=$#
echo "The number of parameters supplied = $tot_params"

dir_params=`expr $# - 1`
echo "The number of dir file names supplied = $dir_params"

#index initialization

index=1

# at least two parameters to be supplied

if test $# -lt 2
then
echo "Please enter at least one directory name parameter and one sort parameter"
exit 1
else
# loop thru the all the directories
# listing the file names
# in ascending or descending order

while test $index -le $tot_params
do
file_name = $($index)

# sort parameter is 'ascending'

if test $# = asc
then
if test -d $file_name
then
echo "listing the files in ascending order....."
ls -l $file_name
index=`expr $index+1`
else
echo "$file_name is not a directory"
exit 1
fi

# sort parameter is 'descending'

elif test $# = dsc
then
echo "File Listing in Descending Order"
if test -d $file_name
then
echo "listing the files in descending order..."
ls -lr $file_name
index=`expr $index+1`
else
echo "$file_name is not a directory"
exit 1
fi

# incorrect sort parameter supplied

else
echo "The Sort argument is $($#)"
echo "The Directory File name is $($index)"
echo "The supplied sort parameter is incorrect"
exit 1
fi
done

fi


if test $? -ne 0
then
echo "sorry..something gone amiss!!!"
else
echo "success"
fi

DCSORT(1)					      DICOM PS3 - Make sorted list of images						 DCSORT(1)

NAME
dcsort - ACR/NEMA DICOM PS3 ... DICOM PS3 - Make sorted list of images SYNOPSIS
dcsort " inputfile1 [ inputfile2 ... ]" [ -v|verbose ] [ -vv|veryverbose ] [ -vvv|veryveryverbose ] [ -index ] [ -show ] [ -interval ] [ -tolerance mm ] [ -check ] [ -checkFoR ] [ -descending ] [ -sortby|k attributename ] DESCRIPTION
dcsort reads the named dicom input files and sorts them by the specified sort key. The sort key should be a single valued numeric attribute, with the exception of ImageOrientationPatient and ImagePositionPatient which are handled as special cases. There is no output by default unless the index or verbose options are specified. OPTIONS
The output and errors go to standard error. The basic input switches are described in dcintro(1). Options specific to this program are: -index Creates a first column of output that is the index in the sort order, starting from 0, and a second column that is the filename. -show Show the value of the sort key after the file name with the -index option -interval Show the interval between values of the sort key, or an error if not equal -tolerance mm The tolerance value in mm to use when comparing intervals between slices; defaults to +/- 0.01 mm if unspecified -check Check that all the images are from the same series. -checkFoR Check that all the images have the same Frame of Reference (UID). -descending Sort in descending, rather than the default ascending, order. -sortby|k attributename Specify attributename as the sort key. ENVIRONMENT
EXAMPLES
% dcsort -index -sortby SliceLocation ./1/[0-9]* 0 ./1/1 1 ./1/2 FILES
