SSH is very powerful, but it could be a big headache for corporate IT guys, if someone open an reverse ssh tunnel from inside a network then it could be a nightmare for the security.

Just found a post explain how to use SSH to create a reverse tunnel, it could be very useful in some case but also could be a terrible nightmare for information safety.

Using SSH to create a local Socks server  to get rid of China Great Firewall has been used widely for people in China.

I love many things in Unix, the “symbolic link” is one of them, fortunately from Windows 2000, NTFS support “juction” which is similar to “symbolic link” in Unix.  Unfortunately,  there is no default command and nor GUI menu to let you do that, all we can do is download a small software:

Junction

Create Win2K NTFS symbolic links

There are also many other cool stuff in System Internals:

“touch” is a unix command used to change the time of a file or directory, touch a directory will not touch the files inside.

To touch recursively, it’s simple with the help of “find” and “xargs”:

e.g.

find . | xargs touch

will touch all files and directories recursively under current directory.

Since directory or filename may contain spaces, the shell script need some additional parameteres:

find "$1" -type f -print0 | xargs -0 touch

In one of my project I need to replace some kind of strings in hundreds if file,  the code paste here is for specific usage, but it could be easily changed to do something else.

It will scan all *.xml files in current directory and in sub directories, replace the value of two attributes to a big value.
