demilited file like this
Input1 file1:45764
Input1 file1:878755
Input1 file1: 899787
Input2 file1: 45676
Input2 file1:769678
Input2 file1: 6454764
and I wish to convert them into
Input1 file1:45764, file1:878755, file1: 899787
Input2 file1:45676, file1:769678, file1: 6454764
Any guess? Thanks in advance
awk '{b[$1]=b[$1] $2$3" "}END{for (i in b) print i,b[i]}' inputFile
will produce output as
Input1 file1:45764 file1:878755 file1:899787
Input2 file1:45676 file1:769678 file1:6454764
what it does?
{b[$1]=b[$1] $2$3" "} creates an array b appends the second and third column(since there was some spaces betweenfile and value in your example).$2$3 into the array. The array is an associative array indexed by the Inputx where x is 1,2...
that is
b['Input1'] = 'file1:45764 file1:878755 file1:899787'
END block is excecuted at end of input file, input,
for (i in b) print i,b[i]} prints the content of b array
And if you want those commas in the output, try
awk '{if(b[$1])b[$1] = b[$1]", "; b[$1] = b[$1] $2 $3}; END{for(i in b)print i, b[i]}'
or the slightly terser
awk '{b[$1]=b[$1](b[$1]?", ":"")$2$3}END{for(i in b)print i,b[i]}'
output
Input1 file1:45764, file1:878755, file1:899787
Input2 file1:45676, file1:769678, file1:6454764
