Check Symlinks in Your Projects with Chklnk
As is the case with every Unix-based operating system, Android uses symlinks. A symbolic link is a special type of file that contains a reference to another file or directory in the form of an absolute or relative path, which affects pathname resolution. In Android, they are mostly used in the /bin and /xbin folders, where all the executing binaries are kept.
If you want to make your own symlinks or get to know which files are a part of Toolbox or Busybox, you can find out manually by entering some commands in Terminal. You can also use a script written by XDA Senior Member LENAROX. Chklnk is nothing but BASH script that can identify the symlinks easily with just one command. After pushing to selected system folder and making it executable, this script can be used to enhance your development projects.
To use this script, your devices must be rooted because you will need to push the script file to your /system partition. You should have also Busybox 1.19.4 or newer installed. Usage is very simple, since you only need to enter the chklnk [file] command to get the list of connections.
Chklnk is a nice way to make your development project better. You can learn more about it by visiting the chklnk.sh script forum thread.
