How to Use ‘find’ Command to Search for Multiple Filenames (Extensions) in Linux

Many times, we are locked in a situation where we have to search for multiple files with different extensions, this has probably happened to several Linux users especially from within the terminal.

There are several Linux utilities that we can use to locate or find files on the file system, but finding multiple filenames or files with different extensions can sometimes prove tricky and requires specific commands.

One of the many utilities for locating files on a Linux file system is the find utility and in this how-to guide, we shall walk through a few examples of using find to help us locate multiple filenames at once.

Before we dive into the actual commands, let us look at a brief introduction to the Linux find utility.

The simplest and general syntax of the find utility is as follows:

# find directory options [ expression ]

Let us proceed to look at some examples of find command in Linux.

1. Assuming that you want to find all files in the current directory with .sh and .txt file extensions, you can do this by running the command below:

# find . -type f \( -name "*.sh" -o -name "*.txt" \)
Find .sh and .txt Extension Files in Linux
Find .sh and .txt Extension Files in Linux

Interpretation of the command above:

  1. . means the current directory
  2. -type option is used to specify file type and here, we are searching for regular files as represented by f
  3. -name option is used to specify a search pattern in this case, the file extensions
  4. -o means “OR”

It is recommended that you enclose the file extensions in a bracket, and also use the \ ( back slash) escape character as in the command.

2. To find three filenames with .sh, .txt and .c extensions, issues the command below:

# find . -type f \( -name "*.sh" -o -name "*.txt" -o -name "*.c" \)

3. Here is another example where we search for files with .png, .jpg, .deb and .pdf extensions:

# find /home/aaronkilik/Documents/ -type f \( -name "*.png" -o -name "*.jpg" -o -name "*.deb" -o -name ".pdf" \)

When you critically observe all the commands above, the little trick is using the -o option in the find command, it enables you to add more filenames to the search array, and also knowing the filenames or file extensions you are searching for.

In this guide, we covered a simple yet helpful find utility trick to enable us find multiple filenames by issuing a single command. To understand and use find for many other vital command line operations, you can read our article below.

      You can use a similar command like this:

      $ find . -newerct "1 Dec 2018" ! -newerct "4 Dec 2018" -ls
      

      For more information, see the find man page.

      That works but it may not be efficient and reliable enough for the job, especially when you want to search in several locations.

    • ls” works only for current directory content listing. It won’t search files recursively in any sub directories if available. So, we need to use find command only which will search in sub-directories also.

  2. Another way is using -regextype and -iregex switch, fore example:

    $ find . -regextype posix-egrep -iregex '.*\.(xml|txt)$' -type f

    The above command find all files with xml or txt extension.
