I have a linux server with mysql installed.There is some data in mysql tables.
Also.I have a .csv file (not from the aforementioned database)
I need to compare the data in the database nad the .csv and print out the difference.
I tried writing a shell script for that but I was unsuccessful.
I need to ask if there's any way I can export the data from mysql tables to .csv file format and use the diff command to see the comparison of the generated file and the file I had initially.
~thanks

Reason: Please use code tags
In sed, 's/\n//' only works if you do an 'N' to read a second line into the buffer.
Once you have the table into something like a csv file, you need to sort and you may need to deal with excess " and such optional encoding. If there are embedded linefeeds in columns, you need to encode them so lines are rows. If the rows are unique, comm is a good tool, else either diff or preprocess sorted through uniq -c and sed to make dups into unique lines with a count suffix before comm.
