I'm working on a bash script and I needed to import some data that I've compressed. However, the tables could also have foreign key constraints that I want ignored. So as I'm importing the dump files, I add "SET FOREIGN_KEY_CHECKS=0" to the file like this:
Found a good example on stackoverflow which taught me how to do this:

Question:
What I need:
Suppose I have two commands,
A
and B
, each of which returns a single-line string (i.e., a string with no newline character, except possibly 1 at the very end). I need a command (or sequence of piped commands) C
that concatenates the output of commands A
and B
on the same line and inserts 1 space character between them.
Answer:
You can use
tr
:{ echo "The quick"; echo "brown fox"; } | tr "\n" " "
OR using sed:
{ echo "The quick"; echo "brown fox"; } | sed -e 'N;s/\n/ /'
OUTPUT:
The quick brown fox
