Converting rows to columns using shell script
I have a script which converts rows to columns.
Code:
file_name=$1
mailid=$2
#CREATE BACKUP OF ORIGINAL FILE
#cp ${file_name}.xlsx ${file_name}_temp.xlsx
#tr '\t' '|' < ${file_name}_temp.xlsx >  ${file_name}_temp.csv
#rm ${file_name}_temp.xlsx
pivot_row=`head -1 ${file_name}`
sed 1d ${file_name}>Sandeep
print "QUARTER\tMETRIC\tMETRIC_VALUE" > pivot_results.xlsx
#LOOP WHILE ROWS ARE LEFT
while IFS= read line
do
   counter=1
        curr_line=$line
        curr_metric=`echo $line | cut -f1 -d","`
        curr_value="dummy"
        #LOOP WHILE COLUMN VALUES FOR THE CURRENT ROW ARE NOT NULL
        while [[ $curr_value != "" ]];
        do
                ((counter=counter+1))
                curr_value=`echo $line | cut -f${counter} -d","`
                if [[ $curr_value != "" ]]; then
                        curr_pivot_value=`echo $pivot_row | cut -f${counter} -d","`
                        print "${curr_pivot_value}\t${curr_metric}\t${curr_value}" >> pivot_results.xlsx
                fi
        done
done < Sandeep
rm Sandeep
echo "Pivoting completed successfully!!"
uuencode pivot_results.xlsx pivot_results.xls | mailx -s PIVOT $mailid
echo "Result mailed to specified id!!"

for example the input is like this
Code:
1990    1991
kiran     201     202

and the output should be like this
Code:
1990     kiran         201
1991     kiran         202

but iam getting the output as
Code:
1990    kiran        201
1991
           kiran        202

my_print_defaults

MY_PRINT_DEFAULTS(1)					       MySQL Database System					      MY_PRINT_DEFAULTS(1)

NAME

       my_print_defaults - display options from option files

SYNOPSIS

       my_print_defaults [options] option_group ...

DESCRIPTION

       my_print_defaults displays the options that are present in option groups of option files. The output indicates what options will be used by
       programs that read the specified option groups. For example, the mysqlcheck program reads the [mysqlcheck] and [client] option groups. To
       see what options are present in those groups in the standard option files, invoke my_print_defaults like this:

	   shell> my_print_defaults mysqlcheck client
	   --user=myusername
	   --password=secret
	   --host=localhost

       The output consists of options, one per line, in the form that they would be specified on the command line.

       my_print_defaults supports the following options.

       o   --help, -?

	   Display a help message and exit.

       o   --config-file=file_name, --defaults-file=file_name, -c file_name

	   Read only the given option file.

       o   --debug=debug_options, -# debug_options

	   Write a debugging log. A typical debug_options string is 'd:t:o,file_name'. The default is 'd:t:o,/tmp/my_print_defaults.trace'.

       o   --defaults-extra-file=file_name, --extra-file=file_name, -e file_name

	   Read this option file after the global option file but (on Unix) before the user option file.

       o   --defaults-group-suffix=suffix, -g suffix

	   In addition to the groups named on the command line, read groups that have the given suffix.

       o   --no-defaults, -n

	   Return an empty string.

       o   --verbose, -v

	   Verbose mode. Print more information about what the program does.

       o   --version, -V

	   Display version information and exit.
