Answer 1

PLEASE GIVE IT A THUMBS UP, I SERIOUSLY NEED ONE, IF YOU NEED ANY MODIFICATION THEN LET ME KNOW, I WILL DO IT FOR YOU

The absolute path file directories can be determined by combining both readlink and dirname command. It can obtained through xargs command.

command for

[- Your_Name_goes_here.dat

-Sales ]  file and directory is :-

readlink -f Sales / Your_Name_goes_here.dat| xargs dirname

The command will return :- /file/data/Sales/Your_Name_goes_here.dat

For example:- Using this command for a file name Sample.txt [readlink -fsample / file.txt| xargs dirname] We get resultant as- /data/example/sample.

**the relative pathname for the following files and directories:

-West1.dat

-RegionB

=> Since the current directory is RegionA so to get the pathname of RegionB. First, we have to go outside of the current file directory using (..).

Further the command for RegionB relative pathname:-

$ cat ..RegionB/West1.dat

$cat command is the concatenate command which is used to read data from the file and gives their content as output.
