1) Creating an empty file. We can use touch command for make a new file in Linux. Syntax is following.
touch [new file name]
2) Deleting a file When deleting a file we use the command rm.
rm [file name]
  3) Copy or move a file. For copy a file to a different location we use cp command.
cp /var/www/html/new.php /temp
To move a file we use same syntax with the command mv.
mv /var/www/html/new.php /temp
4) Renaming a file. The command we use to rename a file is same as moving file.we can do it like this.
mv /var/www/html/new.php /var/www/html/new2.php
