I have a really large tab delimited file (about 6 GB) having 4 columns (pos, start, end, id) and another file containing only ids in one column which is about 200 MB. I want to output a new file with matching ids and the corresponding positions. It also should output a second file wich should contain the line number of the first and second input file, the number of matching and non matching positions by ids. Thanks a lot in advance. Appreciate your help very much. 
 
first file Format 
pos   start   end    id
chr1  11223   11224  rs2342349
chr2  23423   23424  rs6345435
chr3  64564   64565  rs3432456
chr4  56456   56457  rs7979979

second file Format 
id
rs2342349 #only match
rs3274234
rs2342344

Output1
chr1  11223   11224  rs2342349

Output2
Number_pos_1st_file    4
Number_pos_2nd_file    3
Nr_Matching            1
Nr_Non_matching        2
