 4. Confirm checksums via md5. The output file will have one line per file with an md5 checksum and should have the text ‘OK’ at the end of the line.  A line not ending in ‘OK’ indicates that the transfer of this file has failed. 
 
 ```
-grep -v 'OK$' -c \ /scratch/u035/project/trio_whole_exome/data/$project_id/md5_check.txt
+grep -v 'OK$' /scratch/u035/project/trio_whole_exome/data/$project_id/md5_check.txt
 ```
 
 If any files in a download do not have the correct md5 checksum, manually delete the affected files and return to step 3, which will re-download the missing files and re-run the md5 checking. When all md5 checksums are correct, enter today’s date in the ‘Downloaded’ field for the project.
