Solution

The correct command sequence to accomplish this task is:

total=0
for file in $(find /path/to/directory -type f); do
count=$(grep -c "specific word" $file)
total=$((total + count))
done
echo "Total count: $total"

This script works as follows:

  1. It initializes a variable total to 0. This variable will hold the total count of lines containing the specific word across all files.

  2. It uses a for loop to iterate over all files in the specified directory and its subdirectories. The find command is used with the -type f option to only consider files (not directories).

  3. Inside the loop, it uses the grep command with the -c option to count the number of lines in the current file that contain the specific word. This count is stored in the variable count.

  4. It then adds the count from the current file to the total count.

  5. After the loop has processed all files, it prints the total count.
