NAME
       sponge -	soak up	standard input and write to a file

SYNOPSIS

       sed '...' file |	grep '...' | sponge [-a] file

DESCRIPTION
       sponge reads standard input and writes it out to	the specified file.
       Unlike a	shell redirect,	sponge soaks up	all its	input before writing
       the output file.	This allows constructing pipelines that	read from and
       write to	the same file.

       sponge preserves	the permissions	of the output file if it already
       exists.

       When possible, sponge creates or	updates	the output file	atomically by
       renaming	a temp file into place.	(This cannot be	done if	TMPDIR is not
       in the same filesystem.)

       If the output file is a special file or symlink,	the data will be
       written to it, non-atomically.

       If no file is specified,	sponge outputs to stdout.

OPTIONS
       -a
	   Replace the file with a new file that contains the file's original
	   content, with the standard input appended to	it. This is done
	   atomically when possible.
