TASKS

1. Typically, in time every Linux system has a number of symbolic links that are no longer tied with any existing file. This may happen due to various reasons, but ultimately this situation is something that system admin has to deal with. Very frequently the administrator decision is to delete such links. Your task is to write a script which would remove all symbolink links (symlinks) which are linked to no longer existing files / directories. The operation should be performed in the directory specified as the script execution parameter. NO READ COMMAND IN THE NON_INTERACTIVE VERSION AND NO INFINITE LOOPS IT WILL HANG SCRIPTCHECK!

Assuming the script name is scr1and the directory you want to delete the symlinks is Dir, the script should be executed as:

./scr1 dir_name
