That's how you edit files from the shell :-). If you try this :
sed '<sed script>' < file > file
you'll end up with either
1) an error from the shell, if 'noclobber' is set
2) a clobbered file, because the open for writing is done before
the data is read
Thus a temp file is needed for the redirection to work as intended.

I tell you the truth, everyone who sins is a slave to sin. Now a slave
has no permanent place in the family, but a son belongs to it forever.
So if the Son sets you free, you will be free indeed.
