If two files containing following content
file1:
1
2
file2:
3
4
After append : cat file2>>file1
output in file1:
1
23
4
to Add new Line while Appending two files
Command : sed -i -e '$a\' file2 | cat file2 >> file1
From Above
sed -i -e '$a\' file2
This adds \n at the end of the file only if it doesn't already end in a newline. So if you run it twice it will not add another newline.
