dear don cragun,

i use the table for another program, therefore i don't need a pretty print. I need tab's.

and there i found another little problem,
after each line there seems to be a tab, but I don't need this tab for the last field in each line.

how can i easily replace the last tab with a newline.

Code:

fn=$1
fname=${fn%.*}
echo $fname

awk 'BEGIN {FS="\t"};
    NF >= 3 {HD[$1]++; HD[$3]++; PP[$1,$3] = PP[$3,$1] = 1 }
    END    {printf "\t"
        for (i in HD) { printf "%s\t" ,i } printf "\n" #<- here replace the tab with newline
        for (i in HD) {printf "%s\t", i ;
            for (j in HD) { printf "%s\t", PP[i,j]?PP[i,j]:"0" } printf "\n" #<- here replace the last tab with newline
            } }' $fn > $fname.adj

i should read more carefully:

here is the solution:

Code:

awk 'BEGIN {FS="\t"};
    NF >= 3 {HD[$1]++; HD[$3]++; PP[$1,$3] = PP[$3,$1] = 1 }
    END    {
        for (i in HD) { printf "\t%s" ,i } printf "\n"
        for (i in HD) {printf "%s", i ;
            for (j in HD) { printf "\t%s", PP[i,j]?PP[i,j]:"0" } printf "\n"
            } }' $fn > $fname.adj
