Linux command line basic file/folder operations

Operations on files

Create an empty file: Touch + filename # is usually the first touch good one file and then vim this file. Curious why it's called touch.
Delete File: RM + file name # straight out, not to the Recycle Bin

Copy the file to the specified location: CP + file + target directory # For example, the CP file sub copies the file files in the current directory into the current directory sub-directory sub.
Rename/Move files: MV + files (folder) + target directory

# For example, MV Dir1 Dir2/new moved the folder Dir1 (and its contents) to the same level of DIR2 as it did, and renamed New.

# You can also direct MV Dir1 new to rename Dir1 to new but not move.

# if the target already exists, then the moved file/folder will overwrite the original file/folder. Similarly, copying to an existing target can also lead to overwriting.

Actions on a folder
Create empty directory: mkdir + folder name
Delete Empty directory: RmDir + folder name
To delete a directory and what it contains: Rmdir-r + folder name # this r in-R is the word I don't know, please let me know.

Copy the entire folder to another location: Cp-r + folder + Directory location

Operations on a directory

First, make it clear that the main scope of a user activity is/home/username, such as I am/home/abram. If you want to "move the knife" in the other directory of root, it involves troublesome permissions, in short, may be less than root.

Enter directory: CD # Memory: CD change Directroy changing directory

# Assuming that starting in the user directory such as:/home/abram, Linux will show ~ means this directory, also can CD ~ Back to this directory, very handy.

View Catalog contents: LS # Memory: List Listing

# All files, folders are listed. and the colors of the executable files and folders are different. Under my SuSE, it shows:

Green is an executable file, and blue-gray is a folder. The others are ordinary files.

View directory details: Dir # Returns a detailed table equivalent to the upgraded version of LS.

Finally, the use of a "point":

When representing a directory,./represents the current directory,.. /indicates a parent directory, but .../does not indicate a superior directory, not this thing, but. /.. /To achieve. can also continue to set.

Should continue to add, write so much first.
