String to HEX conversion in UNIX
i have this below string which i need to convert it to HEX. i have already tried it but it showing extra few things on it.. let me show what i have done and what is the output i am getting and what is the desired output
the input string is
Code:
 
"!\"\"\"\"\"\"\"!\"\"\"\"\"\"\""

which is technically nothing but below
Code:
!"""""""!""""""""

so as for now consider that string is already present in variable myString
Code:
myString=$( echo $myString | sed 's/\\//g' )
#above command to strip \ in between '"'
 
len=${#myString}
cutString=${myString:1:$len-1}
#above command to strip additional '"' at first and last character.
 
echo $cutString
echo $cutString | xxd  -c 256 -ps
#above command to convert it to HEX

output obtained as of now is as below
Code:
21222222222222222122222222222222220a


BUT the actual output for
Code:
!"""""""!""""""""

should be
Code:
2122222222222222212222222222222222

32 characters.

as according to
HTML Code:

EBOOK-CONVERT(1)						      calibre							  EBOOK-CONVERT(1)

NAME

       ebook-convert - part of calibre

SYNOPSIS

       ebook-convert  input_file output_file [options]

DESCRIPTION

       Convert an ebook from one format to another.

       input_file is the input and output_file is the output. Both must be specified as the first two arguments to the command.

       The  output ebook format is guessed from the file extension of output_file. output_file can also be of the special format .EXT where EXT is
       the output file extension. In this case, the name of the output file is derived the name of the input file. Note that  the  filenames  must
       not  start  with a hyphen. Finally, if output_file has no extension, then it is treated as a directory and an "open ebook" (OEB) consisting
       of HTML files is written to that directory. These files are the files that would normally have been passed to the output plugin.

       After specifying the input and output file you can customize the conversion by specifying various options. The available options depend	on
       the input and output file types. To get help on them specify the input and output file and then use the -h option.

       For full documentation of the conversion system see http://calibre-ebook.com/user_manual/conversion.html

       Whenever you pass arguments to ebook-convert that have spaces in them, enclose the arguments in quotation marks.

OPTIONS

       --version
	      show program's version number and exit

       -h, --help
	      show this help message and exit
