You can try something like:
Code:
awk '{for(i=1;i<=NF;i+=2)printf $i ":" $(i+1) FS}{print ""}' file

What doesn't work? It works with the sample you provided:
Code:
sed 's/\([0-9]\) \([0-9]\)/\1:\2/g' file
1:0 0:1 1:1
0:1 1:1 0:0
1:1 0:0 1:1
1:0 0:1 0:1
0:1 0:0 1:0
1:1 1:1 1:1
0:0 0:0 0:0

The command does assume that the collumns contain only single digit numbers.

Dear all,

I figure it out with perl
Code:
perl -pe 's/([^\s]+)\s+([^\s]+)/$1:$2/g' input_file

Dear Subbeh,

I found out my mistake. The text file I posted was separated by space while my original file was separated by tab. Your script works too. Thank you very much. Smilie

Hello All,

Following may help too.


Code:
awk '{for(i=1;i<=NF;i++) {if(i%2!=0) {a=a" "$i":"$(i+1)} else{if(i==NF) {print a;a=""} }}}' file_name


Output will be as follows.

Code:
 1:0 0:1 1:1 2:2
 0:1 1:1 0:0 3:3
 1:1 0:0 1:1 4:4
 1:0 0:1 0:1 5:5
 0:1 0:0 1:0 6:6
 1:1 1:1 1:1 7:7
 0:0 0:0 0:0 8:8


Thanks,
R. Singh
