So when I type in the following String I keep getting the "No such file or directory" error-

cat /var/log/datasync/connectors/default.pipeline1.mobility-Appinterface.log | grep "value too long for type character varying" -B 7

What in the world am I doing wrong? I can look on the server and see that the files are there, but when I manually try to open them I get nothing. What is going on?
