Permissions when extracting from a tar file 1

[ChrisPhillips]

Is there a way to keep the permissions of the files contained in a tar file, rather than retaining the current file permissions?

For example:
1. I have a tar file that contains a file with execute permissions
2. I then change the permissions of the file on disk to remove the execute permissions
3. If I then extract the file from the tar file it does not have execute permissions

with gnu tar I believe you can pass the -p option to tar

with gnu tar I believe you can pass the -p option to tar. More info:
--mode=PERMISSIONS'
When adding files to an archive, `tar' will use PERMISSIONS for
the archive members, rather than the permissions from the files.
The program `chmod' and this `tar' option share the same syntax
for what PERMISSIONS might be. *Note Permissions: (fileutils)File
permissions. This reference also has useful information for those
not being overly familiar with the Unix permission system.

Of course, PERMISSIONS might be plainly specified as an octal
number. However, by using generic symbolic modifications to mode
bits, this allows more flexibility. For example, the value `a+rw'
adds read and write permissions for everybody, while retaining
executable bits on directories or on any other file already marked
as executable.

`--preserve-permissions'
`--same-permissions'
`-p'
When `tar' is extracting an archive, it normally subtracts the
users' umask from the permissions specified in the archive and
uses that number as the permissions to create the destination
file. Specifying this option instructs `tar' that it should use
the permissions directly from the archive. *

Thanks for that, it worked a treat
