I'm writing a bash script that will deal with blob data that needs to be written to a file. The data inserted into the blob is separated by newlines. The command line mysql -e select blobfield from datatable > file.txt returns data of the form foo\nbar\nbaz\nmoo.
I would like to write it out to a file that looks like
foo
bar
baz
moo

This obviously looks like a regex job, but how do I replace \n with \n?

won't this go to StackOverflow.com? –  動靜能量 Oct 5 '11 at 21:37

I don't know. Shell scripts, especially small ones like this, are a fine line. –  Yitzchak Oct 5 '11 at 21:41

Thanks. It works, but it goes to stdout, not blob.txt. Why not? –  Yitzchak Oct 5 '11 at 21:45
