In the above example, I should remove all characters which follows a ^.
(^H ^@ ^B ^V etc) and It should print This is a Test File used in VI

Is there a program or a cmd which I can use to do this?

Thanks & Regards

Instead of above..solution for the following will help me.

I have to eliminate all characters between ^ and a space in a file.

Following lines -
Test ^ H^@^@^@^@^@^@^B^VDM-BM-$|M-^_M-F^AM- File1
Test^H^@^@^@^@^@^F^A^X^@^SM-s^TM-3M-G^A File2
Should be printed as below
Test File1
Test File2

I used sed '/^/,/ /d' command, but it is not working.

Please help me out.

Thanks & Regards
Sheshadri

STRIP(1)						    BSD General Commands Manual 						  STRIP(1)

NAME
strip -- discard information from ELF objects SYNOPSIS
strip [-d | -g | -S | --strip-debug] [-h | --help] [--only-keep-debug] [-o outputfile | --output-file=outputfile] [-p | --preserve-dates] [-s | --strip-all] [--strip-unneeded] [-w | --wildcard] [-x | --discard-all] [-I format | --input-target=format] [-K symbol | --keep-symbol=symbol] [-N symbol | --strip-symbol=symbol] [-O format | --output-target=format] [-R sectionname | --remove-section=sectionname] [-V | --version] [-X | --discard-locals] file ... DESCRIPTION
The strip utility is used to discard information from ELF objects. The strip utility supports the following options: -d | -g | -S | --strip-debug Remove debugging symbols only. -h | --help Print a help message and exit. --only-keep-debug Remove all content except that which would be used for debugging. -o outputfile | --output-file=outputfile Write the stripped object to file outputfile. The default behaviour is to modify objects in place. -p | --preserve-dates Preserve the object's access and modification times. -s | --strip-all Remove all symbols. --strip-unneeded Remove all symbols not needed for further relocation processing. -w | --wildcard Use shell-style patterns to name symbols. The following meta-characters are recognized in patterns: ! If this is the first character of the pattern, invert the sense of the pattern match. * Matches any string of characters in a symbol name. ? Matches zero or one character in a symbol name. [ Mark the start of a character class. Remove the special meaning of the next character in the pattern. ] Mark the end of a character class. -x | --discard-all Discard all non-global symbols. -I format | --input-target=format These options are accepted, but are ignored. -K symbol | --keep-symbol=symbol Keep the symbol symbol even if it would otherwise be stripped. This option may be specified multiple times. -N symbol | --strip-symbol=symbol Remove the symbol symbol even if it would otherwise have been kept. This option may be specified multiple times. -O format | --output-target=format Set the output file format to format. For the full list of supported formats, please see the documentation for function elftc_bfd_find_target(3). -R sectionname | --remove-section=sectionname Remove the section named by the argument sectionname. This option may be specified multiple times. -V | --version Print a version identifier and exit. -X | --discard-locals Remove compiler-generated local symbols. DIAGNOSTICS
The strip utility exits 0 on success, and >0 if an error occurs. SEE ALSO
