I think you misunderstood me. I was being simple and precise.


input
Code:
x  +  + 100  200
t  -   -  344  333
t  +   - 565  777
g  -  + 789   345

output

Code:
x  +  + 100  200  1stname
t  -   -  344  333   1stname
t  +   - 565  777   2ndname
g  -  + 789   345  3rdname

Is it possible to define the columns with specified symbols like
The script is just written roughly so that you guyz can understand
Code:
awk '{if ($2 == "+" && $3  == "+") print $0, "1stname"} 
elseif {($2 == "-" && $3  == "-" print $0, "1stname"} 
elseif {($2 == "+" && $3  == "-" print $0, "2ndname"} 
elseif {($2 == "-" && $3  == "+" print $0, "3rdname"}' inputfile

NAME
pr - print file SYNOPSIS
pr [ option ... ] [ file ... ] DESCRIPTION
Pr produces a printed listing of one or more files on its standard output. The output is separated into pages headed by a date, the name of the file or a specified header, and the page number. With no file arguments, pr prints its standard input. Options apply to all following files but may be reset between files: -n Produce n-column output. +n Begin printing with page n. -b Balance columns on last page, in case of multi-column output. -d Double space. -en Set the tab stops for input text every n spaces. -h Take the next argument as a page header (file by default). -in Replace sequences of blanks in the output by tabs, using tab stops set every n spaces. -f Use formfeeds to separate pages. -ln Take the length of the page to be n lines instead of the default 66. -m Print all files simultaneously, each in one column. -n Number the lines of each file. -on Offset the left margin n character positions. -sc Separate columns by the single character c instead of aligning them with white space. A missing c is taken to be a tab. -t Do not print the 5-line header or the 5-line trailer normally supplied for each page. -wn For multi-column output, take the width of the page to be n characters instead of the default 72.
