Dear All, My file is like the following: data_1.dat pre= -1908.77 post= -48977.33 diff= -448.947 data_2.dat pre= -444.333 post= -333.545 diff= -777.333 . .
I hope to find out a regular expression subtitution commad to delete everything after "dat" to get a file like:
data_1.dat data_2.dat . .I know visual mode will do the work too. But I still hope to find out the substitution command using regular expression so I can use sed to make it automatic.
Thank you very much.
