Bash Script to Concatenate Lines and Split Sentences in Linux

Write a bash script named 'x.sh' that satisfies the following requirements:

1. In the file 'text.txt', there are some lines that do not end with a period ('.') character. Use the linux command 'sed' to concatenate each of these non-period-ending lines with the following line.

2. For any line in which the word 'because' appears in the middle of the line, start a new line immediately after the word 'because'.
