Column to row Transpose
Hi Folks,

Iam a kinda newbie to unix shell scripting, the scenario is i have a text file containing the following info

HTML Code:
Charlie chicago 15
Charlie newyork 26
jonny chicago 14
jonny newyork 15
joe chicago 15
joe newyork 18
output should be

Code:
Name chicago   newyork       
Charlie   15   26
jonny   14   15
joe   15   18

Output is row to column transpose,chicago & newyork are fixed cities, Person name varies and both cities will be contiguos, if only 1 value per say that is only chicago is there then the value for newyork should be "N/A" in the resulting output.Apreciate your help.

Thank you.

        }
        /chicago/ {
                C[$1] = $3
        }
        /newyork/ {
                N[$1] = $3
        }
        END {
                for ( k in C )
                        print k, C[k]?C[k]:"N/A", N[k]?N[k]:"N/A"

Hi Yoda,
Thanks for your help, iam getting the required output but the values are not matching.
Actually i just found out that there will be only 3 or 6 fixed persons. if possible can you include those restrictions as well.
Can you please update the code. Appreciate your time & effort.

Can you be more specific? May be you can post what you are getting.

By the way this is what I get when I run the code:
Code:
$ cat file
Charlie chicago 15
Charlie newyork 26
jonny chicago 14
jonny newyork 15
joe chicago 15
joe newyork 18

Code:
$ awk '   BEGIN {
                print "Name", "chicago", "newyork"
        }
        /chicago/ {
                C[$1] = $3
        }
        /newyork/ {
                N[$1] = $3
        }
        END {
                for ( k in C )
                        print k, C[k]?C[k]:"N/A", N[k]?N[k]:"N/A"
        }
' OFS='\t' file
Name chicago newyork
joe     15      18
Charlie 15      26
jonny   14      15

Please note that by default, the order which for ( k in C ) loop scans array C is not defined, it is generally based upon the internal implementation of arrays inside awk.

Applying a restriction is pretty much straightforward, you just have to put an if statement to verify if the first field matches the list of names.
