How about writing inplace(1) instead? It should be generally useful
because you can use any filter command such as sed(1), awk(1),
grep(1), sort(1), uniq(1), and so on with it. The name and the
sinopsis would be a matter of controversy, though.
NAME
inplace - processes a file through a filter command inplace
SYNOPSIS
[I can think of several options]
1) inplace file command [args ...] (just one file at a time)
2) inplace 'command [args ...]' files ...
3) inplace command [args ...] ';' files ...
DESCRIPTION
Invokes something similar to:
command args ... < file > temp && mv temp file
or if there is a '{}'in args:
command args ... file ... > temp && mv temp file
(Of course file modes shall be copied)
