In my case, I need to dump the sql result into a file on the client side. This is the most typical use case to off load data from the database. In many situations, you don't have access to the server or don't want to write your result to the server.

mysql -h hostname -u username -ppwd -e "mysql simple sql statement that last for less than a line" DATABASE_NAME > outputfile_on_the.client

The problem comes when you have a complicated query that last for several lines; you cannot use the command line to dump the result to a file easily. In such cases, you can put your complicated query into a file, such as longquery_file.sql, then execute the command.

mysql -h hn -u un -ppwd < longquery_file.sql DBNAME > output.txt

This worked for me. The only difficulty with me is the tab character; sometimes I use for group_cancat(foo SEPARATOR 0x09) will be written as '\t' in the output file. The 0x09 character is ASCII TAB. But this problem is not particular to the way we dump sql results to file. It may be related to my pager. Let me know when you find an answer to this problem. I will update this post.
