trim spaces and replacing value
Hi,
I have a file origFile.txt with values:
origFile.txt
.00~ 145416.02~ xyz~ ram kishor ~? ~ ~783.9
.35~ 765.76~ anh reid~ kelly woodburg ~nancy ~ ~?

Now each row in the file has value for 7 columns with "~" as delimiter.
The requirement was
i)I need to erase the blank spaces between "~" and each column value.
ii) If a column value has a blank space in betwwn (e.g. "ram kishore"), then that blank space shouldn't be removed
iii)If there is no value / only blank spaces in between two consecutive delimiters i.e. "~", then there should
be a single blank space between those two delimiters
iv) If the column value is "?", then the "?" should be removed and the blank spaces should be trimmed for that column value.
i.e. there should not be any value in between the delimiters for that column value.

The output file modFile.txt should look like
modFile.txt
.00~145416.02~xyz~ram kishor~~ ~783.9
.35~765.76~anh reid~kelly woodburg~nancy~ ~

The script I wrote was
sed -e 's/\s*\~\s*/\~/g' -e 's/^\s*//g;' origFile.txt > modFile.txt

The above script solved only the first requirement.
Could anyone please help me in writing the shell script to solve all four requirements listed above?

gensprep

gensprep(8)							 ICU 50.1.2 Manual						       gensprep(8)

NAME

       gensprep - compile StringPrep data from files filtered by filterRFC3454.pl

SYNOPSIS

       gensprep [ -h, -?, --help ] [ -v, --verbose ] [ -c, --copyright ] [ -s, --sourcedir source ] [ -d, --destdir destination ]

DESCRIPTION

       gensprep reads filtered RFC 3454 files and compiles their information into a binary form.  The resulting file, <name>.icu, can then be read
       directly by ICU, or used by pkgdata(8) for incorporation into a larger archive or library.

       The files read by gensprep are described in the FILES section.

OPTIONS

       -h, -?, --help
	      Print help about usage and exit.

       -v, --verbose
	      Display extra informative messages during execution.

       -c, --copyright
	      Include a copyright notice into the binary data.

       -s, --sourcedir source
	      Set the source directory to source.  The default source directory is specified by the environment variable ICU_DATA.

       -d, --destdir destination
	      Set the destination directory to destination.  The default destination directory is specified by the environment variable ICU_DATA.

ENVIRONMENT

       ICU_DATA  Specifies the directory containing ICU data. Defaults to /usr/share/icu/50.1.2/.  Some tools in ICU depend on the presence of the
		 trailing slash. It is thus important to make sure that it is present if ICU_DATA is set.

FILES

       The  following files are read by gensprep and are looked for in the source /misc for rfc3454_*.txt files and in source /unidata for Normal-
       izationCorrections.txt.

       rfc3453_A_1.txt	   Contains the list of unassigned codepoints in Unicode version 3.2.0....

       rfc3454_B_1.txt	   Contains the list of code points that are commonly mapped to nothing....

       rfc3454_B_2.txt	   Contains the list of mappings for casefolding of  code points when Normalization form NFKC is specified....

       rfc3454_C_X.txt	   Contains the list of code points that are prohibited for IDNA.

       NormalizationCorrections.txt
			   Contains the list of code points whose normalization has changed since Unicode Version 3.2.0.
