Removing lines from a file
I'm trying to find a command which will allow me to remove a range of lines (2-4) from a .dat file from the command line without opening the file.

Someone mentioned using the ex command?

Does anyone have any ideas?

thanks

Is there a way of substituting one word for another word, in the same manner?

no, this replaces ALL the occurances of 'oldword' to 'newword' on the CURRENT line where your cursor is.
