Difference operator

Dear All,

Good day, Just i would like to know that is there anything called difference operator in awk?

For example, if a file contains 5 columns (as shown below) with both negative and positive values:
Col1 Col2 Col3 Col4 Col5

I need to calculate the difference between Col1 and Col2, Col2 and Col3, Col3 and Col4, Col4 and Col5, and i need to print out the same in an output file as: New_Col1 New_Col2 New_Col3 New_Col4

Can any one help me in this regard?

Expecting your reply and thanks in advance.

Regards
Fredrick.

CUT-DIFF(1)							  Cutter's manual						       CUT-DIFF(1)

NAME
cut-diff - show difference between 2 files with color SYNOPSIS
cut-diff [option ...] file1 file2 DESCRIPTION
cut-diff is a diff command that uses diff feature in Cutter. It shows difference with color. It's recommended that you use a normal diff(1) when you want to use with patch(1) or you don't need color. OPTIONS
--version cut-diff shows its own version and exits. -c [yes|true|no|false|auto], --color=[yes|true|no|false|auto] If 'yes' or 'true' is specified, cut-diff uses colorized output by escape sequence. If 'no' or 'false' is specified, cut-diff never use colorized output. If 'auto' or the option is omitted, cut-diff uses colorized output if available. The default is auto. -u, --unified cut-diff uses unified diff format. --context-lines=LINES Shows diff context around LINES. All lines are shown by default. When unified diff format is used, 3 lines are shown by default. --label=LABEL, -L=LABEL Uses LABEL as a header label. The first--label option value is used as file1's label and the second --label option value is used asfile2's label. Labels are the same as file names by default. EXIT STATUS
The exit status is 0 for success, non-0 otherwise. TODO: 0 for non-difference, 1 for difference and non-0 for errors. EXAMPLE
In the following example, cut-diff shows difference between file1 and file2: % cut-diff file1 file2 In the following example, cut-diff shows difference between file1 and file2 with unified diff format: % cut-diff -u file1 file2 SEE ALSO
