find command:
The make the /usr/local/bin/makelink file as mentioned above. (If you don't have access permissions, create $HOME/bin and put it in there; change the find command appropriately.)
The missing part in the script should be something like this:
This will work for just about any number of files. Example:
Perl does two substitutions (stuff between s/.../. The first looks for a period NOT preceded by a digit that is followed by a right-bracket. If it finds such a string, it replaces it with [0]. The next looks for a number inside brackets and followed by a period. If it finds such a thing (which it will if the previous step succeeded, or as it must if the previous step failed) it replaces the number found with the next higher number (just adds 1).
The output is sent to the shell which stores that output in the variable "file". The next iteration of the while loop should fail, and then the ln command will do its thing.
Hi all!
I'd like to know the differences between hard links and soft links. I've already read the ln manpage, but i'm not quite sure of what i understood.
Does a hard link sort of copy the file to a new name, give it the same inode number and same rights?
What exactly should I do to do this:... (3 Replies)

I am new in unix plz help me with some example commands ( for creating such links).

I was wondering if it was at all possible to change the timestamp of a soft link. I want to change it to a time in the past before it was created.

I did restore from netbackup for root file system on separate slice instead of corrupted one. After restoration I found there are number of soft link issues lie

eatmydata
eatmydata(1) General Commands Manual eatmydata(1)NAME
eatmydata - transparently disable fsync() and other data-to-disk synchronization calls
SYNOPSIS
eatmydata [--] command [ command arguments ... ]
DESCRIPTION
eatmydata runs a command in the environment where data-to-disk synchronization calls (like fsync(), fdatasync(), sync(), msync() and open()
O_SYNC / O_DSYNC flags) have no effect. LD_PRELOAD library libeatmydata overrides respective C library calls with custom functions that
don't trigger synchronization but return success nevertheless.
You may use eatmydata in two ways. In normal mode, just execute eatmydata directly and pass a command-to-be-run and its arguments via com-
mand line. In order to use symlink mode, create a symlink to /usr/bin/eatmydata with the filename (a.k.a basename) of another program in
the PATH and execute eatmydata via that symlink. Then eatmydata will find that program in the PATH and run it in the libeatmydata environ-
ment repassing all command line options.
OPTIONS
Please note that eatmydata does not process any command line options in symlink mode. All command line options will be repassed to the
underlying executable as-is.
command
The command to execute. It may be either a full path or the name of the command in PATH. In case command cannot be found in PATH,
eatmydata will fail.
command arguments
Arbitrary number of arguments to pass to the command being executed.
-- Optional command separator for compatibility with similar utilities. Ignored at the moment.
EXAMPLES
Given PATH is /usr/bin and both /usr/bin/aptitude and /usr/bin/eatmydata are installed, the following:
$ ln -s /usr/bin/eatmydata ./aptitude
$ ./aptitude moo
is equivalent to:
$ eatmydata -- aptitude moo
Therefore, you may use symlink mode to automatically run specific programs in the libeatmydata environment whenever you run them from PATH.
For example, given standard PATH settings, just do:
# ln -s /usr/bin/eatmydata /usr/local/bin/aptitude
and enjoy sync-free aptitude system-wide.
