Find & Replace with same case letters
I have text with upper and lower case words. I want to find something and replace it with something new. But it should match the case - Meaning - it should replace old upper cased word with NEW upper case word and lower with lower.

example:
Code:
this text is very simple TEXT.

now I want to replace both cases of "text" with word to match with case.
output should be
Code:
this word is very simple WORD.

text is replace with word and TEXT with WORD.

Is there a way to do this in sed or some other command - without the use of a loop.
Thanks in Advance

LEARN ABOUT SUSE

word-list-compress

WORD-LIST-COMPRESS(1)					 Aspell Abbreviated User's Manual				     WORD-LIST-COMPRESS(1)

NAME

       word-list-compress - word list compressor/decompressor for GNU Aspell

SYNOPSIS

       word-list-compress c[ompress] | d[ecompress]

DESCRIPTION

       word-list-compress compresses or decompresses sorted word lists for use with the GNU Aspell spell checker.

COMMANDS

       -c, c, compress
	      compress the plain text word list read from standard input.

       -d, d, decompress
	      decompress the compressed word list read from standard input.

EXAMPLES

       Here are a few examples of how you can use word-list-compress

       word-list-compress d <wordlist.cwl >wordlist.txt
	      Decompress file wordlist.cwl to text file wordlist.txt

       word-list-compress c <wordlist.wl >wordlist.cwl 2>errors.txt
	      Compress wordlist.wl to wordlist.cwl and send any error messages to a text file named errors.txt

       LC_COLLATE=C sort -u <wordlist.txt | word-list-compress c >wordlist.cwl
	      Sort a word list, then pipe it to word-list-compress to create a compressed binary wordlist.cwl file.

       word-list-compress d <words.cwl | aspell create master ./words.rws
	      Decompress a wordlist, then pipe it to aspell(1) to create a spelling list.  Please check the aspell(1) info manual for proper usage
	      and options.

TIPS

       Word-list-compress is best used with sorted word list type files.  It is not a general purpose  compression  program  since  the  resulting
       files may actually increase in size.

       Word-list-compress  accepts  up to 255 text characters in the range of {0x21...0xFF}. If your word list requires a larger character set for
       certain languages or longer length for multi-word, scientific, medical, technical or other use, then it is recommended  that  you  compress
       your word list using prezip-bin(1)

DIAGNOSTICS

       Word-list-compress  normally exits with a return code of 0. If it encounters an error, a message is sent to standard error output (stderr),
       and word-list-compress exits with a non-zero return value.  Error messages are listed below:

       (display help/usage message)
	      Unknown command given on the command line so word-list-compress displays a usage message to standard error output.

       Corrupt Input
	      This is only for the decompression command d.  The input file is of an unknown format or the input file/stream  is  corrupted.   You
	      may  have  some valid output, but word-list-compress could not complete the process.  If the input file is a compressed wordlist but
	      you have no output file, then it may be a newer prezip-bin(1) version of compressed file, if so, try  decompressing  the	file  with
	      prezip-bin(1) instead.

       Output Data Error
	      The output is full, write protected, or has an error and can no longer be written to.

SEE ALSO

       aspell(1), aspell-import(1), prezip-bin(1), run-with-aspell(1)

       Aspell is fully documented in its Texinfo manual.  See the `aspell' entry in info for more complete documentation.
