ha ha i forgot command how to delete file
 

It's look like funny i had installed Redhat on my pc and i forgot the command to delete a file.and another thing is that how to create a new file and i like to write some chracter and like to save with a particular name please ....... help me for this

to delete a file use
rm -f filename
to create an empty file issue
touch filename
then you can open it and write whatever you want
also you can create an empty file and start editing it right away with any text editor, for instance vi
vi filename

also to add to this, rmdir will remove a directory.

man rmdir
man rm
for all available options.
