    If you want to find the file whose name is technical.txt in a current working directory, run following command:

    # find ./ -name technical.txt

    If you want to find all the file who name is starting with technical, run following command:

    # find ./ -name technical*

    Find all the files whose name is support.txt and contains both capital and small letters in /tmp directory.

    # find /home -iname support.txt

    If you want to find all files and want to ignore file with a specific pattern, you can invert the search with “-not” or “!”. If you use “!”, you must escape the character so that bash does not try to interpret it before find can act:

    # find -not -name technical.txt


    # find \! -name technical.txt

    Find all the files under /tmp directory with name technical.txt.

    # find /tmp -name tecmint.txt

    If you want to find all the file under /tmp directory who name is starting with technical, run following command:

    # find /tmp -name technical*

    Search files into multiple directories.

    # find /opt /usr /var /etc -name support.txt -type f

    Find files with different extensions or patterns.

    # find . -type f \( -name "*sh" -o -name "*xml" -o -name "*html" \)

    Finding by Type

    You can specify the type of files you want to find with the “-type” parameter. Use following command:

    # find / -type f technical.txt

    Some of the most regular descriptors that you can use to indicate the kind of document are here:

  • f: regular file
  • d: directory
  • l: symbolic link
  • c: character devices
  • b: block devices
  • We can search all the files that end with “.php”.

    # find /home -type f -name "*.php"

    To find all hidden files, use below command.

    # find /home -type f -name ".*"

    Enjoy it!
