the data tab delimited. tried using sed , awk, can't correct syntax. there other command can use can have desired output?

awk -v ofs="\t" '         fnr==1{                                 # read first line                 max=nf                          # save no of fields                 print                           # print header                 next                            # go next line         }   nf>max{                                       # if no of fields greater max fields                 split($0,fd)                    # split record fields sep, , store in array fd                 nf=max-1                        # set nf max-1                  for(i=max; in fd; i++)        # loop through fd max                        print $0,fd[i];          # print modified record, , field                 next                            # stop processing go next         }$1=$1                                  # $1=$1 making tab o/p field separator unmodified record     ' file 

input

$ cat f id  country  place  1         mall park  2   b       beach  3   c       hotel resort  4   d       museum  5   e       garden 

output

$ awk -v ofs="\t" 'fnr==1{max=nf; print; next}nf>max{split($0,fd); nf=max-1; for(i=max; in fd; i++)print $0,fd[i]; next}$1=$1' f id  country  place 1     mall 1     park 2   b   beach 3   c   hotel 3   c   resort 4   d   museum 5   e   garden
