It is risky to remove symlink targets! Imagine there's a symlink to /etc ...!
The following checks the link target to have at least two /. But e.g. a link to /etc/passwd would still delete /etc/passwd.

I have a folder<abc> under /root folder. I want to create a symlink such that when i click on folder<abc> under root, should display my home folder (home/krish).

Hi all,
I want to create a symlink on a link file, i mean, there is a file which is actually a symlink of some version. Now i want to create one more symlink on that link file.
EX: there is a file:
uat -> version
prod -> version
Now i want to create one more link on these 'uat' and... (1 Reply)

I have a target directory, there are some files and directories in "target_dir".
I have a symbol link: my_link -> <target_dir>
The target directory name is NOT known to the script (because it is varying), while the link name is always fixed.

Hi Forums,
I got a little problem, I made a few modifications to the code of the launch script of a testing server(minecraft) and now updating is broken aswell as the automatic directory creation.

Hello,
can someone please suggest or is it possible to hide the path for the link from viewing it from remote users.
for examples.

Hi All,
Is there any way to create a symlink that will point to last 1000 line of a log file. My symlink will always point to "tail -1000 logfile".
This can be achieved by writing a script and scheduling with high frequency, but I am looking for some other alternatives.
Please let me know... (8 Replies)
Hi,
I wanted to configure new iscsi port on HPUX system, i added the target port address and configured it, once done, went to array side and searched for that host iqn number , but was nt able to find the same, came to host, then when i ran "iscsiutil -pVS" command it gave me below result

I am trying to setup my plex server to use symlinks rather than host the movie files.

I know how to create a symlink but I am getting an error message that the file already exists. Also, my symlink doesn't point from target directory to the path correctly,

mcxmap
mcxmap(1) USER COMMANDS mcxmap(1)
NAME
mcxmap - permute or remap the indices of graphs and matrices.
SYNOPSIS
mcxmap -imx fname (input) [-o fname (output)] [-make-map (output map file name)] [-make-mapc (output map file name)] [-make-mapr (output map
file name)] [-cmul a (coefficient)] [-cshift b (translate)] [-rmul c (coefficient)] [-rshift d (translate)] [-mul e (coefficient)] [-shift f
(translate)] [-map fname (row/col map file)] [-rmap fname (row map file)] [-cmap fname (column map file)] [-mapi fname (row/col map file
(use inverse))] [-rmapi fname (row map file (use inverse))] [-cmapi fname (column map file (use inverse))] [-tab fname (read (and map) tab
file)]
DESCRIPTION
This utility relabels graphs or matrices. Its main use is in applying a map file to a given matrix or graph. A map file contains a so called
map matrix in mcl format that has some special properties (given further below). The functionality of mcxmap can also be provided by mcx, as
a mapped matrix (i.e. the result of applying a map matrix to another matrix) is simply the usual matrix product of a matrix and a map
matrix. However, mcx will construct a new matrix and leave the original matrix to be mapped alone. When dealing with huge matrices, consid-
erable gains in efficiency memory-wise and time-wise can be achieved by doing the mapping in-place. This is what mcxmap does. In the
future, its functionality may be embedded in mcx with new mcx operators.
The special properties of a map matrix are
o The column domain and row domain are of the same cardinality.
o Each column has exactly one entry.
o Each row domain index occurs in exactly one column.
These properties imply that the matrix can be used as a map from the column domain onto the row domain. An example map matrix is found in
the EXAMPLES Section.
OPTIONS
-o fname (output file)
Output file.
-imx fname (input file)
Input file.
-map fname (row/col map file))
-rmap fname (row map file)
-cmap fname (column map file)
-mapi fname (row/col map file (use inverse))
-rmapi fname (row map fil (use inverse))
-cmapi fname (column map fil (use inverse))
Different ways to specify map files.
-make-map (output map file name)
-make-mapc (output map file name)
-make-mapr (output map file name)
Generate a map that maps the specified domain onto the appropriate canonical domain and write the map matrix to file.
-cmul a (coefficient)
-cshift b (translate)
These options have affect if neither a column map file nor column canonification is specified. If any of the first two options is used,
column indices i are mapped to a*i+b.
-rmul c (coefficient)
-rshift d (translate)
These options have affect if neither a row map file nor row canonification is specified. If any of the first two options is used,
indices i are mapped to c*i+d.
-mul e (coefficient)
-shift f (translate)
If a map file is specified for a given domain, neither a map file nor canonification is specified. If any of the first two options is
used, the indices i will be mapped to e*i+f.
-tab fname (read (and map) tab file)
This option requires the -map option. mcxmap will output the mapped tab definition.
EXAMPLES
The matrix below has two canonical domains which are identical. It denotes a map of the canonical domain onto itself, in which node 0 is
relabeled to 8, node 1 is relabeled to 5, et cetera.
