Thanks , franklin you method worked, i knew i had to use a while loop and getline in there just didnt know the proper order Smilie

Hi everyone, im trying to make the following command line shorter by introducing a script that join up all the grep commands

./new1a < numbers.txt | grep -i -v '^a ' | grep -i -v '^the ' | grep -i -v '^or ' | sort -f

How would I go about merging all the greps into a scripe and putting all the words that should be excluded into a data file

With awk you can do something like this:

awk '
' "datafile.txt" "numbers.txt"

The OP deleted his question, for clarity, this was the request:
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:


Desired output:

hi how are you
what are you doing
yes sir

Try this:

./new < numbers.txt | awk '
  BEGIN{while(getline < "datafile.txt" > 0 ) {
