Create Carriage Return using SED
I am hoping someone can help me with a solution to this problem using SED. My issue is actually two-fold. First, I have an order file that is sent to us from another system, however, there has been a change in current processes that requires a carriage return added to the end of each order. The file being sent to us is a .CSV with the orders running into each other as shown below:

Code:
0000235298~0080387170~~0000013338~COMPANY~CONTACT~ADDRESS~CITY~STATE~ZIP~US~INFO1~EMAIL~~INFO2~INFO3~PS0000235700~0080387811~~0000402296~ COMPANY ~~ ADDRESS ~ CITY ~STATE~ZIP~US~~ EMAIL ~~INFO2~INFO3~FS

The first order ends at PS and the next order begins directly after. The current software is capable of reading this properly. The problem begins with an additional software package that requires there to be a Carriage Return after PS.

My second dilemma is that there are two new fields being added to each order as shown below:

Code:
0000235298~0080387170~~0000013338~COMPANY~CONTACT~ADDRESS~CITY~STATE~ZIP~US~INFO1~EMAIL~~INFO2~INFO3~PS~Y~30000235700~0080387811~~0000402296~ COMPANY ~~ ADDRESS ~ CITY ~STATE~ZIP~US~~ EMAIL ~~INFO2~INFO3~FS
~Y~3]

Now there is a 3 at the end of the order. The final output of the information above must look like the format below:

Code:
0000235298~0080387170~~0000013338~COMPANY~CONTACT~ADDRESS~CITY~STATE~ZIP~US~INFO1~EMAIL~~INFO2~INFO3~PS~Y~3
0000235700~0080387811~~0000402296~ COMPANY ~~ ADDRESS ~ CITY ~STATE~ZIP~US~~ EMAIL ~~INFO2~INFO3~FS ~Y~

Also keep in mind there may or may not be a Y or even a 3 at the end, leaving data possibly looking like this PS~~. However, the system will know what to do as long as there is a Carriage Return at the end. [FONT=Calibri]The only tip i can think of regarding patterns is there will always be 18 ~ delimiters if that helps with finding a pattern.

I hope I have not confused this and that someone might be able to help me out with this. Thank you for any help you might have as well as your time.

In addition to the pattern I mentioned already, you can basically state that after the 18th ~ delimiter if there is a 3 then add a carriage return after the 3 otherwise add a carriage return after the 18th ~ delimiter.

zipgrep

ZIPGREP(1)						      General Commands Manual							ZIPGREP(1)

NAME

       zipgrep - search files in a ZIP archive for lines matching a pattern

SYNOPSIS

       zipgrep [egrep_options] pattern file[.zip] [file(s) ...]  [-x xfile(s) ...]

DESCRIPTION

       zipgrep	will  search  files  within  a ZIP archive for lines matching the given string or pattern.  zipgrep is a shell script and requires
       egrep(1) and unzip(1) to function.  Its output is identical to that of egrep(1).

ARGUMENTS

       pattern
	      The pattern to be located within a ZIP archive.  Any string or regular expression accepted by egrep(1) may be used.  file[.zip] Path
	      of  the  ZIP archive.  (Wildcard expressions for the ZIP archive name are not supported.)  If the literal filename is not found, the
	      suffix .zip is appended.	Note that self-extracting ZIP files are supported, as with any other ZIP archive; just	specify  the  .exe
	      suffix (if any) explicitly.

       [file(s)]
	      An  optional list of archive members to be processed, separated by spaces.  If no member files are specified, all members of the ZIP
	      archive are searched.  Regular expressions (wildcards) may be used to match multiple members:

	      *      matches a sequence of 0 or more characters

	      ?      matches exactly 1 character

	      [...]  matches any single character found inside the brackets; ranges are specified by a beginning character, a hyphen, and an  end-
		     ing character.  If an exclamation point or a caret (`!' or `^') follows the left bracket, then the range of characters within
		     the brackets is complemented (that is, anything except the characters inside the brackets is considered a match).

	      (Be sure to quote any character that might otherwise be interpreted or modified by the operating system.)

       [-x xfile(s)]
	      An optional list of archive members to be excluded from processing.  Since wildcard characters  match  directory	separators  (`/'),
	      this  option  may  be used to exclude any files that are in subdirectories.  For example, ``zipgrep grumpy foo *.[ch] -x */*'' would
	      search for the string ``grumpy'' in all C source files in the main directory of the ``foo'' archive, but none in any subdirectories.
	      Without the -x option, all C source files in all directories within the zipfile would be searched.

OPTIONS

       All options prior to the ZIP archive filename are passed to egrep(1).
