In software engineering, clobbering a file or computer memory is overwriting its contents. Jargon File defines the term as follows: "To overwrite, usually unintentionally: 'I walked off the end of the array and clobbered the stack. ' Compare mung, scribble, trash, and smash the stack. " Often this happens unintentionally, e.g. , using the '>' redirection operator. To prevent unintentional clobbering, various means are used.

  • In software engineering, clobbering a file or computer memory is overwriting its contents. Jargon File defines the term as follows: "To overwrite, usually unintentionally: 'I walked off the end of the array and clobbered the stack. ' Compare mung, scribble, trash, and smash the stack. " Often this happens unintentionally, e.g. , using the '>' redirection operator. To prevent unintentional clobbering, various means are used. For example, the setting shell parameter "set -o noclobber" or "set noclobber" will prevent '>' from clobbering making it to issue an error message instead: >set -o noclobber >echo hello > bb >echo hello > bb bb: File exists. In makefiles, a common target clobber means complete cleanup of all unnecessary files and directories produced by previous invocations of the make command. It is a more severe target than clean and is commonly used to uninstall software. Some make-related commands invoke "make clobber" during their execution. They check the CLOBBER environment variable. If it is set to OFF then clobbering is not done. In assembler programming, the term 'clobbered registers' is used to denote any registers whose value may be overwritten during the course of executing an instruction.
