Terminal-Based-File-Explorer

This Repository contains the Terminal Based File Explorer built as part of Advanced Operating Systems Coursework.

BRIEF:

This Repository is the implementation of File-Explorer in Terminal as part of Advanced Operating Systems Coursework using the proper invocations of various system call and not relying on ncurses for GUI.

ASSUMPTIONS:

As per the ASSIGNMENT PDF:

• The root of your application should be the directory where the application was started.
• Home - h key should take the user to the home folder (the folder where the application was started).

Makefile users:

Binaries are present in /bin

• make: Builds the binaries
• make clean : Remove the object files
• make run : Build and run the application

For Debugging:

Makefile is already configured to use debugging just use the attached .vscode configuration.

Libraries Used:

• termios.h
• sys/ioctl.h
• sys/stat.h
• dirent.h
• grp.h
• pwd.h
• fcntl.h
• bits/stdc++.h

---

NORMAL MODE :

Navigation Keys:

• ↑: Moves the cursor arrow upwards.
• ↓: Moves the cursor arrow downwards.
• ←: Goes back to previously visited directory.
• →: Goes to next directory.
• h: Goes to Home which is currently set.(where application starts from)
• Backspace : Goes to parent directory.
• k: Scroll Window Up
• l: Scroll Window down
• q: Quit the Explorer

---

COMMAND MODE:

PATHS:

• . : current directory
• ~ : home directory

All the paths will be in reference to one of theses two.

Command List:

copy : Copies the files and folders from current directory to destination directory.

copy <source_file(s)/folder(s)> <destination_directory>

move : Moves the files and folders from current directory to destination directory.

copy <source_file(s)/folder(s)> <destination_directory>

rename : Renames the file.

rename <old_filename> <new_filename>

create_file : Can create 1 or more files in the destination path specified.

create_file <file_name(s)> <destination_path>

create_dir : Can create 1 or more directories in the destination path specified.

create_file <directory_name(s)> <destination_path>

delete_file : Can delete a file from the specified path.

delete_file <file_path>

delete_dir : Can delete a directory and all its contents from the specified path.

delete_dir <dir_path>

goto : Traverses to the directory.

goto <directory_path>

search : Searches for a file/folder recursively starting from the current directory.

search <filename/foldername>

ESC : Pressing ESC key will go to normal mode.

q : Pressing q and Enter from command mode will exit the application.

Live Update in COMMAND MODE:

All the commands are built in a way that their actions are reflected in a live way in the directory listing of the normal mode , to provide users a sense that their commands are actually working.

ADDITIONAL IMPLEMENTATIONS:

• The cursor is hidden in normal mode and an arrow is printed to point the directory entry.
• Auto resize: Window resize automatically resizes everything in the explorer as well as maintains the command buffer in command mode.
• It has alternate linux mode configuration that can be switched on that changes the paths to use normal linux paths. Just change the boolean flag to true.
