How To Find a Text File with a Specific Word on Ubuntu

Ubuntu 17

In this article, we will explore different methods to find a text file that contains a specific word on Ubuntu. This can be achieved using various command-line tools or GUI applications.

Quick Answer

To find a text file with a specific word on Ubuntu, you can use the grep command in the terminal. Simply navigate to the desired directory and run the command grep -rIH 'word' .. This will display a list of files that contain the specified word. Alternatively, you can use the find command with grep by running find . -type f -exec grep -IH 'word' {} \;. Another option is to use the GUI application gnome-search-tool, which allows you to search for files containing a specific word. Install it using sudo apt-get install gnome-search-tool and then use the application to perform the search.

Using the grep Command

The grep command is a powerful tool that searches input files for lines containing a match to a given pattern list. Here’s how to use it:

  1. Open the terminal.
  2. Navigate to the directory where you want to start the search. For instance, if you want to start the search from the root directory, you would use the cd / command.
  3. Run the following command: grep -rIH 'word' .
    • -r or --recursive performs a recursive search in all subdirectories.
    • -I ignores binary files. This is useful as binary files can sometimes disrupt the output.
    • -H or --with-filename displays the filename where the word is found.
    • Replace ‘word’ with the specific word you’re searching for.
    • The . at the end specifies the current directory as the starting point for the search.

This command will display a list of files that contain the specified word, along with the matching lines in these files.

Using the find Command with grep

The find command is used to search and locate the list of files and directories based on conditions you specify. Here’s how to use it with grep:

  1. Open the terminal.
  2. Navigate to the directory where you want to start the search.
  3. Run the following command: find . -type f -exec grep -IH 'word' {} \;
    • find . performs a search for files starting from the current directory.
    • -type f filters the search to only include regular files.
    • -exec executes the grep command on each file found.
    • -H displays the filename where the word is found.
    • Replace ‘word’ with the specific word you’re searching for.
    • {} is a placeholder that find replaces with the current file name being processed.
    • \; indicates the end of the -exec command.

This command will display a list of files that contain the specified word, along with the matching lines in these files.

Using a GUI Application

For those who prefer a graphical interface, you can use the gnome-search-tool:

  1. Install the gnome-search-tool package by running sudo apt-get install gnome-search-tool in the terminal.
  2. Open the “Search for files” application (sometimes called “Search” or “Files”).
  3. Select “Select More Options” or a similar option to access advanced search options.
  4. Enter the word you want to search for in the “Contains the text” field.
  5. Choose the directory or drive where you want to search.
  6. Click “Find” or a similar button to start the search.

The application will display a list of files that contain the specified word.

Conclusion

Finding a text file with a specific word on Ubuntu can be achieved through various methods. Whether you prefer using the command line with tools like grep and find, or a GUI application like gnome-search-tool, Ubuntu provides you with the flexibility to choose the method that suits you best.

How can I search for a case-insensitive word in a text file on Ubuntu?

To search for a case-insensitive word in a text file on Ubuntu, you can use the -i option with the grep command. The command would be grep -ri 'word' file.txt. This will search for the word ‘word’ in the file ‘file.txt’ regardless of its case.

Can I search for multiple words in a text file using `grep`?

Yes, you can search for multiple words in a text file using grep. To do this, you would separate the words with the pipe symbol |. For example, to search for either ‘word1’ or ‘word2’ in a file, you would use the command grep -rH 'word1\|word2' file.txt.

How can I search for a whole word using `grep`?

To search for a whole word using grep, you can use the -w option. For example, if you want to search for the word ‘word’ as a whole word in a file, you would use the command grep -rHw 'word' file.txt. This will match ‘word’ as a standalone word and not as part of another word.

Can I search for a word in multiple files or directories at once using `grep`?

Yes, you can search for a word in multiple files or directories at once using grep. To do this, you would specify the files or directories you want to search after the grep command. For example, to search for the word ‘word’ in multiple files, you would use the command grep -rH 'word' file1.txt file2.txt file3.txt. To search in multiple directories, you would use the command grep -rH 'word' dir1 dir2 dir3.

How can I search for a word recursively in subdirectories using the `find` command?

To search for a word recursively in subdirectories using the find command, you can combine it with the grep command. The command would be find . -type f -exec grep -H 'word' {} \;. This will search for the word ‘word’ in all regular files within the current directory and its subdirectories.

Can I search for a word in a specific file extension using the `find` command?

Yes, you can search for a word in a specific file extension using the find command. To do this, you would add the -name option to the find command followed by the file extension. For example, to search for the word ‘word’ in all text files with a .txt extension, you would use the command find . -type f -name "*.txt" -exec grep -H 'word' {} \;.
