How to find stuff on your Mac hard drives


Here are my notes on finding (and replacing) stuff on a Mac.



Hidden files

If you are searching for hidden files:

How to Search the Content of Your Files on Windows

Using Command line

  1. cd to the path

  2. To find text “Exception” within files of “.md” type at the current folders down:

    find . –name “*.md” –print | xargs grep “Exception”

Find “foo” within files by diving recursively into folders :

grep -ri “foo” .

Remove the i to not ignore case distinctions.

Display print only the filenames with GNU grep:

grep -r -l “foo” .


Use -print0 option to find filenames that contain spaces or other metacharacters:

find /path/to/dir -type f -print0 xargs -0 grep -l “foo”

Find file names

Find files using file-name ( case in-sensitve find)

find -iname “MyCProgram.c”

Execute commands on files found by the find command

find -iname “MyCProgram.c” -exec md5sum {} \;

Find all empty files in home directory

find ~ -empty
