grep -trying to get it work work


I would like to run a grep command. I type the grep command and press enter, but nothing happens, I just get a cursor that blinks. When I press CTR+C I get my cursor back, but no output.

I typed at the command prompt:
grep 10.151.253

I imagine that I need to press a special key besides enter, but I don't know what.

You need to supply input to grep

either the output of another command or a filename

i.e.

grep 10.151.253  fileName

or

somecommand |grep 10.151.253

another possibility is

grep -rn 10.151.253 directory

grep -n 10.151.253 file1 file2 file3  directory/file4  /path/to/somedir/file5

or    grep -n 10.151.253 *

for that matter
