Find Multiple words in a file

Shell Programming and Scripting

Hi all,
I have trouble in finding the multiple word in .txt file. Please help me with any solution.
I have 10,000 .txt files and in each file i have to search specific word but more than one, like
(data, machine learning, clustering) and all these keywords should be case insensitive because inside file same word is in caps and non caps as well. And the main objectives is to copy that file to another folder if the key word is present.

thanking you in advance.

Regards

create a file call it patterns.

machine
learning
data
cluster

cd /path/to/many/files
for fname in *
do
    fgrep -Fq patterns  $fname
    [ $? -eq 0 ]  && mv $fname  /path/to/another/place/${fname}
done

Your requirement is not yet clear.
The following wants at least 2 matching lines, where a match is any of the word1|word2|word3.
For the copy action we put a loop around it.

for file in *.txt
do
 if [ -f "$file" ] &&
  [ `egrep -ic 'data|machine learning|clustering' "$file"` -gt 1 ]
 then
  echo cp "$file" /another/folder
 fi
done

This might give "too many arguments". Then use find, feeding a read loop:

find . \! -name . -prune -type f -name "*.txt" |
while read file
do
 if [ `egrep -ic 'data|machine learning|clustering' "$file"` -gt 1 ]
 then
  echo cp "$file" /another/folder
 fi
done
The

\! -name . -prune prevents find from visiting sub folders.

This should do the trick according to your specs:

cp $(egrep -il 'data|machine learning|clustering' *) new-folder
