I would like to know is it possible through symbolic (soft) link to move files from one location (A) to another (B) when files are getting created in the A location.
So you have some program creating files in some directory (e.g. in /fixed/location/), and you want the data to be elsewhere (e.g /data/dir/somefile.txt...)
If you know in advance the name of the created files, you could make them symbolic links before starting the program:
ln -s /data/dir/somefile.txt /fixed/location/file.txt
and if you create that symbolic link before running the program, it will write the data into /data/dir/somefile.txt even if that file does not exist (but the directory /data/dir should exist when you type that ln -s)
Another (Linux specific) possibility is to make a bind mount. If e.g. you want the data inside /usr/src/ to reside in /home/Src/ you could first mkdir /home/Src then e.g. add the following line in your /etc/fstab file:
/usr/src /home/Src none bind 0 0
I'm actually doing that (on /usr/src and /usr/local) for every Linux system where /home/ is a different filesystem, because I want them to be in the same backed up file system as /home/
