Thank you very much RudiC. Actually I am an embryology biologist and I don't have any computer science background and I am a totally rookie. I have to deal with some very large data set from the experimental work recently and I don't know how to cope with them. I learned that some unix command can help me to do that, then I tried to use some very simple command like such as sed or awk to do some basic work and it is really amazing for me. However, I don't have ability to deal with the more complicated problem even these problems seems very naive for you computer guys. So that's why I post many questions on this forum recently. I wish I can figure out some problems but I really don't have the ability right now. Actually I am studying some programming skills by myself now and I hope I can also help some other people like me in the future. I raelly appreciate anyone helped me.

GIT-COLUMN(1)							    Git Manual							     GIT-COLUMN(1)

NAME

       git-column - Display data in columns

SYNOPSIS

       git column [--command=<name>] [--[raw-]mode=<mode>] [--width=<width>]
		    [--indent=<string>] [--nl=<string>] [--padding=<n>]

DESCRIPTION

       This command formats its input into multiple columns.

OPTIONS

       --command=<name>
	   Look up layout mode using configuration variable column.<name> and column.ui.

       --mode=<mode>
	   Specify layout mode. See configuration variable column.ui for option syntax.

       --raw-mode=<n>
	   Same as --mode but take mode encoded as a number. This is mainly used by other commands that have already parsed layout mode.

       --width=<width>
	   Specify the terminal width. By default git column will detect the terminal width, or fall back to 80 if it is unable to do so.

       --indent=<string>
	   String to be printed at the beginning of each line.

       --nl=<N>
	   String to be printed at the end of each line, including newline character.

       --padding=<N>
	   The number of spaces between columns. One space by default.
