Shell : Script that iterates all it directory and sub directory and find the word search and print the complete file path.

Shell Scripting @ Freshers.in

One common task is searching for a specific word in all files in a directory and its subdirectories. This is useful to quickly find files that contain a specific keyword.

To search for a specific word in all files in a shell script, we can use the grep command with the -r option. The -r option searches all files in a directory and its subdirectories. We can also use the -l option to print only the file name that matches the search pattern, and the -i option to ignore the case of the search pattern.

Here’s an example script that searches for the word “search” in all files in the current directory and its subdirectories and prints the complete file path:

#!/bin/bash
echo "Searching for files containing the word 'search':"
for file in $(grep -rli search .); do
  echo "$file"
done

Let’s break down how this script works.

The first line #!/bin/bash is called a shebang and specifies which shell should be used to execute the script. In this case, we are using the bash shell.

The script uses a for loop to iterate over all files in the current directory and its subdirectories that contain the word “search”.

Inside the loop, the echo command is used to print the complete file path of each file that contains the word “search”.

The grep command with the -rli options is used to search for the word “search” in all files in the current directory and its subdirectories. The -r option searches recursively, -l option prints only the name of the matching files, and the -i option makes the search case-insensitive. The grep command returns the names of all files that contain the word “search”.

We can run the script by saving it as a file, for example search-files.sh, and then making it executable using the chmod command:

chmod +x search-files.sh

We can then execute the script by running:

./search-files.sh

This will output the complete file path of all files in the current directory and its subdirectories that contain the word “search”. Searching for a specific word in all files in a directory and its subdirectories is a common task in shell scripting. We can use the grep command with the -rli options to search for the word, and a for loop to iterate over all matching files and print their complete file path.
