I have two files: File1
ARS-BFGL-BAC-10975 0.9303 688423261 1 01/04/2015 0.9983763305 ARS-BFGL-BAC-11025 0.9092 688423261 1 01/04/2015 0.9983763305 ARS-BFGL-BAC-11044 0.9626 688423261 2 01/04/2015 0.9983763305 ARS-BFGL-BAC-11193 0.9544 688423261 1 01/04/2015 0.9983763305 ARS-BFGL-BAC-10975 0.9303 688423263 1 01/04/2015 0.9983763305 ARS-BFGL-BAC-11025 0.9092 688423263 1 01/04/2015 0.9983763305 ARS-BFGL-BAC-11044 0.9626 688423263 2 01/04/2015 0.9983763305 ARS-BFGL-BAC-11193 0.9544 688423263 1 01/04/2015 0.9983763305 File2:

I only want to keep rows in the output that are in file 2 based on column1.
I have tried join but I cant get it to work right-it will tell me my files are not sorted
join -j 1 -o 1.1,1.2,1.3,1.4,1.5,1.6,2.2,2.3 <(sort -k1 file1) <(sort -k1 file2) Preferably I would prefer an awk command. File 1 will be very large. I have tried
awk 'FNR==NR{a[$1]=$2 FS $3;next}{ print $0, a[$1]}' file2 file1 > output Any help would be much appreciated. Thanks
Sorry I cant comment below but just to clarify file not all rows in column1 in file 1 will be in file2.
The awk command
awk 'FNR==NR{a[$1]=$2 FS $3;next} $1 in a {print $0, a[$1]}' will only keep the amount of rows there is in file 2. But ideally what I want is were for expample ARS-BFGL-10975 is repeated twice (realistically way more) to appear twice in my output.
Thanks for the help so far
