You are tasked with writing a Bash script that searches for specific text patterns within a directory containing thousands of files. The script needs to be efficient and fast. Which of the following commands should you use within your script?1.0 Marks grep -r "pattern" /path/to/directoryfor file in $(ls /path/to/directory); do grep "pattern" $file; donefind /path/to/directory -type f -exec grep "pattern" {} \;cat /path/to/directory/* | grep "pattern"grep "pattern" /path/to/directory/*

Which command is commonly used in Linux for pattern matching using regular expressions?*1 pointa) regexb) grepc) rmatchd) find

You are a software developer working on a feature for a file management system. The feature must search through directories and subdirectories to find files matching certain criteria (e.g., file type, size). The search should delve deeply into directories before moving to the following directory at the same level. Which algorithm would be most suitable for searching deeply through directories and subdirectories to find specific files? 1. Breadth-first search 2. Depth-first search 3. Uniform-cost search Write a Python script to implement the selected algorithm. The script should read an input.txt file containing the input, which has a tree structure where each node represents a directory, and its children represent subdirectories/files. An example is given below. 'root': ['dir1', 'dir2'], 'dir1': ['file1', 'file2'], 'dir2': ['dir3'], 'dir3': ['file3'], 'file1': [], 'file2': [], 'file3': [] The output should be a list representing the order in which files are found. The output for a query to find “file3” in the above input file system is given below ['root','dir2', 'dir3', 'file3'] Ensure you follow the coding standards using meaningful variable names and adding comments to explain your logic. At the top of the script, after importing the libraries, add a block comment and mention which of the above algorithms is used in your script. Also, ensure that your script is error-free. This is a group project, and one submission per group is sufficient.

What two arguments commonly follow the grep command?1 pointThe string to search for and the file to search throughThe file to write to and the string to add to itThe file name to search for and the directory to search throughThe file to move and the new file location

You are writing a Bash script that needs to count the number of lines containing a specific word in multiple text files within a directory and its subdirectories. The script should provide a total count at the end. Which command sequence correctly accomplishes this task?0.5 Markstotal=0for file in $(find /path/to/directory -type f); docount=$(grep -c "specific word" $file)total=$((total + count))doneecho "Total count: $total"total=0for file in $(ls /path/to/directory); docount=$(grep -o "specific word" $file | wc -l)total=$((total + count))doneecho "Total count: $total"total=0for file in $(find /path/to/directory -type f); docount=$(grep -i -o "specific word" $file | wc -l)total=$((total + count))doneecho "Total count: $total"total=0for file in $(ls /path/to/directory); docount=$(grep -c "specific word" $file)total=$((total + count))doneecho "Total count: $total"total=0for file in $(find /path/to/directory -type f); docount=$(grep -o "specific word" $file | wc -l)total=$((total + count))doneecho "Total count: $total"
