copy files containing specific words in a specified line
 
Anyone knows how to use bash script to copy / move files containing particular words in a specified line to other folders?

for example:

lots of text files *.txt in a folder /tmp
I'd like to move files containing "my book" in the line 9 to another folder /home/abenmao/my book/, and move files containing a word "my dog" in the line 9 to another folder /home/abenmao/my dog/ ...

Thank you for looking into my question

grep with the -l switch will list only the file names. Test it first:
Code:
grep -l "my book" *
Now use cp to copy the hits to somewhere else.
Code:
cp `grep -l "my book" *` /home/abenmao/mybook/
Repeat with 'my dog' instead of 'my book'.

A requirement is "pattern in line 9". I would keep it simple and use a loop like this:
Code:
#!/bin/bash
while read file
do
  if sed -n 9p "$file" | grep -q "my book"
  then
    mv "$file" "/home/abenmao/my book/"
  elif sed -n 9p "$file" | grep -q "my dog"
  then
    mv "$file" "/home/abenmao/my dog/"
  fi
done < <(find /tmp -type f -name "test*")
As a general tip, I would not use blank spaces in the directory names. This makes things a bit more complicate in shell scripting. Use _ (underscore) instead.

ehh.. missed the line-9 requirement. Your script is pretty neat.
