cp (copy) command
The cp command copies files from one location to another. If the destination file exists, it will be overwritten; if the destination directory exists, the file will be copied to that directory.
Copy a file:
cp file1 file2
The above cp command copies the contents of the file1 to the file2.
Back up the copied files:
cp -b file1 file2
Copy folders and subfolders:
cp -R sqlmap sqlmap1
The above cp command copies folders and subfolders from sqlmap to sqlmap1.
mv (move) command
Use it to move/rename files from one directory to another. The mv command is different from the cp command. The mv command completely moves the file from the source and moves the file to the specified directory. The cp command just copies the contents of the file from one file to another.
To rename/move a file:
mv file1.txt file2.txt
This command renames the file1.txt file to file2.txt.
To move a directory
mv sqlmap tmp
In the above command, if the tmp directory already exists, the mv command will move all files, directories, and subdirectories under the sqlmap folder/directory to the tmp directory. If there is no tmp directory, it will rename the sqlmap directory to the tmp directory.
Move multiple files to another directory
mv file1.txt tmp / file2.txt newdir
This command moves the file1.txt file in the current directory and the file2.txt file in the tmp folder/directory to the newdir directory.
rm delete command
The rm command is used to remove/delete files in a directory.
Here the rm command will remove/delete the file file1.txt.
Delete the directory tree:
rm -ir tmp
Here the rm command recursively deletes the contents of all subdirectories under the tmp directory. You will be prompted for the deletion of each file, and then delete the tmp directory itself.
Delete multiple files at once.
rm file1.txt file2.txt
The rm command deletes both file1.txt and file2.txt.
