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

Thank you so much. Got a better idea on loops inside awk. Code makes a lot of sense.
