I ran the following bash command to merge several big files
cat file1.txt file2.txt file3.txt file4.txt > merged.txt
The process is very long as the files make about 12 GB each. On the
activity monitor (Mac OSX 10.11.3), under the tab called
Disk, I see the following entry for the process of interest
How is it possible in this
cat process that more bytes are being written than read?
