4. Run the jar file given in the folder using

    java -jar File_System_Simulator.jar

Installation - Windows

Some Sample Commands Usages

1. mkdir

mkdir is used to make a new directory

Usage

 mkdir dirname

2. cd

cd is a command can be used to change a directory

Usage

cd dirname

3. ls

ls command is used to list all files of an directory

Usage

or

ls dirname

4. touch

touch is used to create a regular file

Usage

touch filename

5. cat

cat is used to display contents of a file

Usage

cat filename

6. rmdir

rmdir is used to delete a directory

Usage

rmdir filename

7. rm

rm is used to delete a file

8. lnk

link is used to create shortcuts of a file or directory

9. mv

10. grep

grep can be used for pattern matching

11. Traversal through '/', '..', '.'

Multilevel traversal is possible using '/' to specify the path as we go from each outer directory to inner directory. The name for the root folder is '/' which can be accessed from any folder. The parent can be accessed using '..' meanwhile the current folder by '.' .This can be used for any command where path is used

Some Example Usages

1. Move to root

cd /

2. Make a directory in parent directory

mkdir ../dirname

2. Make a in a inner directory from root (Note that all the directory except the outer ones must exist)

mkdir /dir1/dir2/dir3/dirname

12. Piping

Piping can be used here to send the output of one command as a parameter to the next one

Usage (Here the content of the file is given as the 2nd parameter to the grep command)

cat filename | grep pattern
