Talking about backup, it is important for you to understand how rsync command works to backup files effectively. The existing file has been moved to readme.txt~ and the new file copied as readme.txt as shown below. $ cp -backup readme.txt /home/thegeekstuff/projectbackup/ In this example, the readme.txt exists in both project/ and projectbackup/ directory, and while copying it from project/ to projectbackup/, the existing readme.txt is backed up as shown below: $ cd projectbackup In case if the destination file is already present with the same name, then cp allows you to backup the destination file before overwriting it. $ cp -r src/ bin/ /home/thegeekstuff/projectbackup/ 3. $ cp *.c /home/thegeekstuff/projectbackup/src/Д¬opy multiple directories as shown below. In this example, all c extension files gets copied to /home/thegeekstuff/projectbackup/src/ directory. If the source files has a common pattern, use wild-cards as shown below. $ cp global.c main.c parse.c /home/thegeekstuff/projectbackup/src/ You can copy more than one file from source to destination as shown below:

Src/ bin/ doc/ lib/ test/ readme.txt LICENSE 2. Src/ bin/ doc/ lib/ test/ readme.txt LICENSE $ cp project/readme.txt projectbackup/ДЄ directory (and all its content) can be copied from source to destination with the recursive option -r as shown below: $ ls project If you want to copy a file from one folder to another with the same name, just the destination directory name is good enough as shown below. The following example copies the file from project/readme.txt to projectbackup/readme-new.txt $ cp project/readme.txt projectbackup/readme-new.txt To copy a file, you need to pass source and destination to the copy command. Copy a file or directory from source to destination The general form of copy command: cp source destination 1.

You already know that it is used to copy one or more files or directories from source to destination. We discuss using the less command in this article.Cp is one of the basic command in Unix.

Start typing the text you want to add to the file. cat > file4.txtДЄ cursor will appearВ on the next line below the prompt.

Type the cat command followed by the double output redirection symbol ( >) and the name of the file you want to add text to. If you want to add a bit of new text to an existing text file, youВ use the cat command to do it directly fromВ the command line (instead of opening it in a text editor). Then, type two output redirection symbols ( >) followed by the name of the existing file you want to add to.

Type the cat command followed by the file or files you want to add to the end of an existing file. cat file1.txt file2.txt file3.txt | sort > file4.txtДЄs we mentioned earlier, there is also a way append files to the end of an existing file.

All the lines of text in the result file will be sorted alphabetically.

Then, type the output redirection symbol ( >) followed by the name of the file into which you want to copy the combined text. To do this, enter the basic cat command we previously showed you followed by the pipe command (|) and the sort command. If youвЂ™re combining lists of items from multiple files and you want them alphabetized in the combined file, you can sort the combined items in the resulting file. If you openВ file4.txt (either with the cat command or with the text editor of your choice), you should find that it contains the text of the first three text files.
