Don't understand your first question. But for your 2nd question, to search for word in files in directory,

Pure shell solution

shopt -s nullglob
for file in *
do
  while read -r line
  do
     case "$line" in
        *searchword*) echo "$file: $line";;
     esac
  done < "$file"
done

Using grep

grep -l "pattern" *

Using awk

awk '/pattern/{print FILENAME": "$0}' *

For the second question:

find . | xargs grep word_to_search

It will list recursively all files from the current dir (.) . Then it gives them as input to grep.

For the first question: if you plained to constantly monitor the files changes, you may consider to use svn.

You can monitor the files using inotifywait(1).

inotifywait efficiently waits for changes to files

It is suitable for waiting for changes to files from shell scripts

I agree with others, the first part of your question is too vague. Why not add some detail like 'I expected the file to change like XXXX', how do I confirm that?'

You wrote

what command searches for particular word in all files in one directory

Just use plain grep, i.e.

cd myDataDir
grep 'searchTarget' *

I hope this helps.

P.S. as you appear to be a new user, if you get an answer that helps you please remember to mark it as accepted, and/or give it a + (or -) as a useful answer.
