.SH "DESCRIPTION"
|
|
.PP
|
|
\fBsponge\fR
|
|
reads standard input and writes it out to the specified file\&. Unlike a shell redirect,
|
|
\fBsponge\fR
|
|
soaks up all its input before writing the output file\&. This allows constructing pipelines that read from and write to the same file\&.
|
|
.PP
|
|
|
|
\fBsponge\fR
|
|
preserves the permissions of the output file if it already exists\&.
|
|
.PP
|
|
When possible,
|
|
\fBsponge\fR
|
|
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\&.)
|
|
.PP
|
|
If the output file is a special file or symlink, the data will be written to it, non\-atomically\&.
|
|
.PP
|
|
If no file is specified,
|
|
\fBsponge\fR
|
|
outputs to stdout\&.
|
|
.SH "OPTIONS"
|
|
.PP
|
|
\fB\-a\fR
|
|
.RS 4
|
|
Replace the file with a new file that contains the file\*(Aqs original content, with the standard input appended to it\&. This is done atomically when possible\&.
