What is rvfp in linux?
#cp - rvfp dir1 dir2. cp command in Linux with examples. In this tutorial, we learn cp command in Linux with examples. Linux basic commands that can create,Remove,Copying,Moving files and directories. This document discusses evolution of Linux and basic commands.
Syntax:
It has three principal modes.
If the command contains two file names, then it copies the contents of 1st file to the 2nd file. If the 2nd file doesn’t exist, then first it creates one, and content is copied to it. But if it existed then it is simply overwritten without any warning. So be careful when you choose the destination file name.
Suppose there is a directory named geeksforgeeks having a text file a.txt.
Example:
If the command has one or more arguments, specifying file names and following those arguments, an argument specifying directory name then this command copies each source file to the destination directory with the same name, created if not existed but if already existed then it will be overwritten, so be careful!
Example:
Suppose there is a directory named geeksforgeeks having a text file a.txt, b.txt and a directory name new in which we are going to copy all files.
Note: For this case the last argument must be a directory name. For the above command to work, Dest directory must exist because cp command won’t create it.
If the command contains two directory names, cp copies all files of the source directory to the destination directory, creating any files or directories needed. This mode of operation requires an additional option, typically R, to indicate the recursive copying of directories.
In the above command, cp behavior depends upon whether Dest_directory exists or not. If the Dest_directory doesn’t exist, cp creates it and copies content of Src_directory recursively as it is. But if Dest_directory exists then copy of Src_directory becomes sub-directory under Dest_directory.
There are many options of cp command, here we will discuss some of the useful options: Suppose a directory named geeksforgeeks contains two files having some content named as a.txt and b.txt. This scenario is useful in understanding the following options.
The `cp` command is an essential tool which is used for copying files or groups of files and directories in Unix-Like operating systems. If we talk about its syntax it takes at least two filenames in as an argument (source and destination). As mentioned, the command has three principles: copying two file names, copying one or more arguments, and copying two directory names. Then we also mention the multiple options available while using `cp` command: `-i` , `-b` , `-f“ , `-r` , `-p`. To work with easy in Unix shell for file management one should know the proper working of `cp` command.
Linux basic commands that can create,Remove,Copying,Moving files and directories.
Create Files In Linux:
Cat:
Cat is a command to create a files and modify the file content too.
Syntax: cat > filename
Example: cat > newfile Welcome to linux
To open the file use the following syntax.
Syntax: cat filename
Example: cat newfile Welcome to linux
To update the content in the file
Syntax: cat >> filename
Example: cat >> newfile ctrl+d (exit from the updated file)
Touch:
Touch is the command to create multiple files at time with empty content.
Syntax: touch
Example: touch file1 file2 file3
To view the created files use the following command,
$ls
Create Directories In Linux:
Mkdir:
mkdir is the command to create directory.Using this command multiple directories can also create.
Syntax: mkdir dirname
Example: mkdir newdir
How to make multiple directories using mkdir,
Options to create multiple directories using options.
example:$mkdir -p dir1/{dir2/{dir5,dir6},dir3/{dir7,dir8},dir3/{dir9,dir10}}
To view the directories structure use the following command,
Syntax:tree dirname
Example: tree dir1/
Copying Files into single and multiple directories
CP:
cp command is used to copy files or directories from source to destination(directories).
Syntax: cp
Example: cp newfile dir1
To view the copied files in directory follow the below steps,
#cd dir1 #ls
Copy directories from one location to another locations,
Example: cp -rvfp dir1 dir2 (copy dir1 to dir2) #cd dir2 #ls
MV:
mv command is used to move the files and directories from source location to destination.
Syntax: mv
Example:mv newfile dir1
Move directories from one location to another location,
Example: mv dir1 dir2
Rename the file name with mv command,
Syntax: mv
Example: mv file1 file2
Rename directory using mv command,
Syntax: mv
Example: mv dir1 dir2
RM:
rm is the command to remove files and directories.
Syntax: rm
Example: rm file1
To remove the files forcefully here is the command,
Syntax: rm -f
Removing Empty directory,
While removing directory need to remove files.Here is the example to remove the directory which is empty,
Syntax:rmdir
Example: rmdir dir1
Remove directory with files inside,
To remove the directory which contain files in two ways,
1.Remove the files inside the directory and use rmdir command.
2.use rm -rf
Syntax: rm -rf
Example: rm -rf dir1
