The OP deleted his question, for clarity, this was the request:
Quote:
Output of his command "./new < numbers.txt ":

hi how are you
what are you doing
or am i sleeping
the zebra ate the lion
yes sir
a banana fell

File datafile.txt:

a
the
or

Desired output:

hi how are you
what are you doing
yes sir

Try this:

Code:
./new < numbers.txt | awk '
  BEGIN{while(getline < "datafile.txt" > 0 ) {
    arr[$1]=$1
  }
  close("datafile.txt")
}
!arr[$1]{print}
'

Xmark datafile DESCRIPTION
Xmark is a shell script that reads the indicated datafile and compiles a benchmark which it writes to standard output. It writes three numbers: A weighted performance number for the x11perf results. A weighted performance number for a standard SparcStation 1, with SunOS 4.1.2, X11R5 Xsun, and a CG3 dumb Color Frame Buffer. The Xmark, which is the ratio of the two numbers above. The datafile must be an ordinary file, produced by x11perf in the following way: x11perf -display display -v1.3 -rop GXcopy GXxor -all > datafile It is possible to run the GXcopy and GXxor tests separately, as long as they are concatenated to the same output file: x11perf -display display -v1.3 -rop GXcopy -all > datafile x11perf -display display -v1.3 -rop GXxor -all >> datafile or x11perf -display display -v1.3 -rop GXxor -all > datafile x11perf -display display -v1.3 -rop GXcopy -all >> datafile FILES
