Moving a line to the end of the file

Shell Programming and Scripting

I have a file with different directories in it. I would need to move one line within the file to the end of the list. Also not there could be blank line in the middle of it. Example

/vol/fs1

/vol/fs2 

/vol/fs3
/vol/fs4
/vol/fs5
/vol/fs6

/vol/fs7

So I would need /vol/fs2 after /vol/fs7 like so

/vol/fs1

/vol/fs3
/vol/fs4
/vol/fs5
/vol/fs6

/vol/fs7

/vol/fs2

Thanks

What criteria made you choose "/vol/fs2" to be moved to the end of the file?

awk 'END {print t} /fs2/{t=$0;next}1' infile

Thanks in advance
