Wasted quite some time to figure out why [ "$actual" = "$expected" ] in my shell script did actually report inequality. Printing both variables with echo "'$expected'" and also piping them through sha1sum like echo -n "$expected" | sha1sum (even tried without the -n flag) clearly showed that they were the same. In the end, set -x saved my day. actual contained captured stdout of a process with proper newlines, but I had used expected="foo\\nbar", hence the comparison saw a literal backslash-n and no newline…
