Linux finds file names with a given string

Question

I'm on Ubuntu and I would like to find all the files in the current directory and subdirectories whose name contains the string "John". I know that grep can match the contents in files, but I have no idea how to use it with file names. Any help would be appreciated.

Answer 1

Use the find command ,

 find . -type f -name "*John*" 

Answer 2

The correct answer has already been set, but in order to learn how to help myself, I thought that I would choose something useful in a different way; if you can summarize what you are trying to achieve in one word, Linux has a powerful help function.

 man -k <your search term> 

What this means is to list all the teams that have a search query in the short description. This is usually a pretty good chance that you will find what you need.;)

This conclusion can sometimes be somewhat overwhelming, and I would recommend narrowing it down to executable files rather than all available man pages, for example:

 man -k find | egrep '\(1\)' 

or, if you also want to search for commands that require higher privilege levels, for example:

 man -k find | egrep '\([18]\)' 

Answer 3

use ack your simple. just type ack <string to be searched>

Answer 4

The find will take a long time, as it scans real files in the file system.

The fastest way is to use the locate command, which will immediately give the result:

 locate "John" 

If the command is not found, you must first install the mlocate package and run the updatedb command to prepare the search database for the first time.

Answer 5

This is a very simple solution using the tree command in the directory you want to find. -f shows the full path to the file, and | used to pass tree output to grep to find the file containing the string filename in the name.

 tree -f | grep filename
