I have a text file in the below sample format



File.txt



Record1 20 23;
Record2 256;
Record3 45 679 98 1;


The no of columns in each line can vary. I want to change the file with only two columns based on column 1 Value. Below is the target output.



File_2_Columns.txt



Record1 20;
Record1 23;
Record2 256;
Record3 45;
Record3 679;
Record3 98;
Record3 1;

          Here's one way



          awk '{for(a=2;a<=NF;a++){printf "%s %s%cn",$1,$a,a==NF ? "" : ";"}}' File.txt >File_2_Columns.txt


          Good luck with the rest of your homework ;-)



          If teacher is giving extra credits for shortest answer, try



          awk '{for(a=2;a<=NF;){printf"%s%cn",$1" "$a,a++-NF?";":""}}' File.txt >File_2_Columns.txt
