I just made this directory seconds ago, but it has 5 links. Why?
Code:
$ ls -lid ../tmp . a/.. b/.. c/..
278622 drwxr-xr-x 5 user users 96 May 22 07:39 .
278622 drwxr-xr-x 5 user users 96 May 22 07:39 ../tmp
278622 drwxr-xr-x 5 user users 96 May 22 07:39 a/..
278622 drwxr-xr-x 5 user users 96 May 22 07:39 b/..
278622 drwxr-xr-x 5 user users 96 May 22 07:39 c/..
$
However . and .. should be the only hard links to directories. The ln command will not hardlink directories. But the link() system call will if it is invoked by root. Doing this can ruin the tree structure of a filesystem.
as kernel keeps track of user activities on a file by its INODE number and I node table .
what is the structure of Inode table. and where does this Inode table mapped into?user space or kernel space?
is the Inode Number is fixed for a file till its deletion?

I try to understand the meaning of an inode. I wonder whether
an inode is unique (I'm pretty sure it is) and
whether it remains the same inode regardless of whatever happens to the file, dir or whatever?
I read somewhere that an inode stores info about the file, size... so changing the... (4 Replies)

dbs-edit-patch
DBS-EDIT-PATCH(1) Debian Build System DBS-EDIT-PATCH(1)NAME
dbs-edit-patch - Edit a DBS patch
SYNOPSIS
dbs-edit-patch [options] patch
dbs-edit-patch -h|--help
DESCRIPTION
dbs-edit-patch is script to generate or modify patches for Debian source-packages in DBS format.
WARNING
dbs is deprecated, please switch to the `3.0 (quilt)' Debian source package format instead. See http://wiki.debian.org/Projects/Deb-
Src3.0#FAQ for a short guide how to do it.
OPTIONS -h, --help
Show summary of options.
-t dir, --tmpdir=dir
Directory for the temporary files, default is /tmp or if set $TMP.
-s dir, --sourcedir=dir
Top level directory of the debian-package source-tree, default is the present working directory.
-P dir, --sourcepatchdir=dir
Directory containing upstream patches.
-T dir, --sourcetardir=dir
Directory containing the upstream tarball.
-p level, --strip=level
Striplevel -p of patch (Option -p of diff(1)), accepted values are 0 and 1, default is 0.
ENVIRONMENT VARIABLES
TMP Sets the directory for the temporary files, can be overridden with -t dir.
debian/vars
dbs-edit-patch will automatically use variables defined in the optional debian/vars file.
When a file debian/vars.in exists and debian/vars either does not exist or is older than any of the following files: debian/vars.in,
debian/changelog, debian/rules or debian/control, then dbs-edit-patch will try updating the vars file by running the following command
make -f debian/rules -W debian/vars.in debian/vars
EXAMPLES
Edit the 021_debian patch of Heimdal:
~/heimdal-0.3d> dbs-edit-patch -t/tmp 021_debian
Extracting source heimdal-0.3d.tar.gz ... successful.
Applying patch 001_replay ... successful.
etc.
Copying heimdal-0.3d to heimdal-0.3d-old ... successful.
Applying patch 021_debian ... successful.
Edit files under /tmp/021_debian/heimdal-0.3d as required, then put a short description into /tmp/021_debian/patch-description if desired,
and finally execute /tmp/021_debian/dbs-update-patch to save the results.
Technical note: dbs-edit-patch extracts all patches before 021_debian into /tmp/021_debian/heimdal-0.3d, copies the result to
/tmp/021_debian/heimdal-0.3d-old, and applies the last patch 021_debian (if it exists). Also, it creates a shell script which will create
the diff between the old and new directories:
~/heimdal-0.3d> ls -la /tmp/021_debian
