    Study Notes

    File Access in Linux

    • File access in Linux is determined by the assigned user and group permissions as well as the owner's rights.
    • Users can access files or folders based on the read, write, and execute permissions set for their user type: owner, group, or others.
    • Hidden files in Linux are prefixed with a dot (.), and can be accessed using commands like ls -a or nano .filename.

    Mounting and File Extensions

    • Linux does not rely on file extensions for file type identification, unlike Windows, which uses extensions to associate file types with applications.
    • Drives in Linux are mounted at specific locations within the filesystem, while in Windows they are associated with drive letters (e.g., C:).

    Naming and Type Distinction

    • Linux distinguishes normal files from hidden files with the dot prefix and considers hidden files as part of the overall filesystem.
    • Changing a file from 'test.txt' to 'TeST.txt' in Linux results in the two being treated as distinct files, demonstrating case sensitivity.

    Compression Formats and Extensions

    • Files compressed with bunzip2 will be decompressed, while .bz2 indicates a file compressed using bzip2.
    • XZ compression adds a .xz extension, and files compressed with gunzip usually bear the .gz extension.
    • When dealing with tarballs compressed with Gzip, the tar command should be used to extract the files.

    Pathnames and Commands

    • The root of the filesystem in Linux is denoted by a forward slash (/), while in Windows it is designated using a backslash ().
    • Components of a pathname in Linux are arranged in a hierarchical structure, separated by slashes (/).
    • The mkdir command is used to create directories, while mv is used to move or rename files.

    File and Directory Management

    • The cp command duplicates files or directories, with the -r option necessary for recursive copying of directories.
    • To create an empty text file, use the touch command; ls is often run before using rm -r for confirmation.
    • For symbolic links to directories, the ln -s command can be employed.
    • The rmdir command can only delete empty directories, while rm -r can handle directories containing files and subdirectories.

    Permission Management and Best Practices

    • Changing file and folder permissions in Linux can be done using the chmod command.
    • The Filesystem Hierarchy Standard (FHS) guides users on filesystem structure and defines shareable versus unshareable files.
    • Unshareable files often contain system-level information, while shareable files are accessible by multiple users.

    Command Functions

    • The command ls lists files and directories; without options, it displays names in a column.
    • Using the -d option with ls shows the details of the directory itself rather than the contents.
    • ls -l provides a detailed list of files, where 'l' indicates long format, giving information such as permissions, size, and modification date.
