kgz
|
|
|
|
kgz is like gzip, but supports compressing and decompressing to a different
|
|
directory than the source file is in.
|
|
|
|
Usage: kgz [-l] [-k] [-m] [-x] [--uid N] [--gid N] source [target]
|
|
|
|
If target is a directory, the basename of the source file will be used
|
|
as the target filename. Compression and decompression is selected
|
|
based on whether the source filename ends in ".gz".
|
|
|
|
Flags:
|
|
-l level Compression level (0-9). Only meaningful when compressing.
|
|
-u Do not restrict the size during decompression. As
|
|
a safeguard against gzip bombs, the maximum size
|
|
allowed is 32 * the compressed file size.
|
|
-k Keep the source file (do not remove it after successful
|
|
compression or decompression).
|
|
-m On decompression, set the file mtime from the gzip header.
|
|
-x On compression, include uid/gid/mode/ctime in the gzip Extra
|
|
field so that decompression can restore them. The Extra payload
|
|
is an ASN.1 DER-encoded struct.
|
|
--uid N When used with -x, set UID in Extra to N (override source).
|
|
--gid N When used with -x, set GID in Extra to N (override source).
|
|
|
|
Metadata notes:
|
|
- mtime is stored in the standard gzip header and restored with -m.
|
|
- uid/gid/mode/ctime are stored in a kgz-specific Extra subfield as an ASN.1
|
|
DER-encoded struct. Restoring
|
|
uid/gid may fail without sufficient privileges; such errors are ignored.
