i need to do a demonstration on the following question and i really don't know what command to use for these.i need to do this demo using linux terminal.plz help me and thanks in advance.

Append a statement, namely “test” to the file named “linux”.


I tried to google looking what is the meaning for append and it says ;

To place after, or at the end of, a character, a line, or a file. In the vi editor, certain commands let you append text in a document. In the Bourne and C shells, the symbol )) allows you to append output to an existing file (or create a new file if the file does not yet exist).

plz explain and help me.thanks alot for all your help.

plz help

echo test >> linux

That will append the word test to the end of a file named linux.

thanks alot mate...

just another doubt:

how to check whether the name test already added?

is there any other command to check this.

plz help.....

Checking to see if a file exists is slightly more complicated, and since this sounds like a homework assignment you're going to have to learn to use google on your own.
