You can write to stdin all you want, it just won't work. If you want it to do anything meaningful you have to reopen stdin as something you can write to.

This is likely to be a dumb one.
How can I use sed to substitute string occurances having it read from an input file and write to this very same file ?
I have a file with lots of occurances of '2006', I want to change it to '2007', but I'd like these changes to be saved on the input file.

git-hash-object
GIT-HASH-OBJECT(1) Git Manual GIT-HASH-OBJECT(1)
NAME
git-hash-object - Compute object ID and optionally creates a blob from a file
SYNOPSIS
git hash-object [-t <type>] [-w] [--path=<file>|--no-filters] [--stdin [--literally]] [--] <file>...
git hash-object [-t <type>] [-w] --stdin-paths [--no-filters]
DESCRIPTION
Computes the object ID value for an object with specified type with the contents of the named file (which can be outside of the work tree),
and optionally writes the resulting object into the object database. Reports its object ID to its standard output. This is used by git
cvsimport to update the index without modifying files in the work tree. When <type> is not specified, it defaults to "blob".
OPTIONS
-t <type>
Specify the type (default: "blob").
-w
Actually write the object into the object database.
--stdin
Read the object from standard input instead of from a file.
--stdin-paths
Read file names from the standard input, one per line, instead of from the command-line.
--path
Hash object as it were located at the given path. The location of file does not directly influence on the hash value, but path is used
to determine what Git filters should be applied to the object before it can be placed to the object database, and, as result of
applying filters, the actual blob put into the object database may differ from the given file. This option is mainly useful for hashing
temporary files located outside of the working directory or files read from stdin.
--no-filters
Hash the contents as is, ignoring any input filter that would have been chosen by the attributes mechanism, including the end-of-line
conversion. If the file is read from standard input then this is always implied, unless the --path option is given.
--literally
Allow --stdin to hash any garbage into a loose object which might not otherwise pass standard object parsing or git-fsck checks. Useful
for stress-testing Git itself or reproducing characteristics of corrupt or bogus objects encountered in the wild.
