Again, this looks like homework. Please do not post homework.

You are obviously able to access the Internet since you are posting here. Do a web seach on the topic and you will find all the information on ln(1) that you could ever wish for.

If you have no access to UNIX/Linux man pages, simply seach the Web for "linux man ln(1)" or similar.

As mentioned in one of your other posts, read some books or tutorials for this basic question:

hard lick-- used in cases when you want the link to be in the same file system. In this case the inode for both link and the file is the same. If you want to move the shardlink to another location or you want to move the original file, it does not affect either of them.

command is ln "file name" "link"

this can not be used on directories. and can be used only in the same fS and not outside file systems

Soft links: used when you want a temporary link. ths inode values are different here for link and the file.
this can be both for file and directories.
If the source file gets deleted the link will be removed at next reboot
. This can extend across file systems

command is ---ln -s "file" "link"

please reverrt if you have any qureries.
