Piping find into grep is often more convenient; it gives you the full power of regular expressions for arbitrary wildcard matching.

For example, to find all files with case insensitive string "foo" in the filename:

~$ find . -print | grep -i foo

find will find all files that match a pattern:

find . -name "*foo"

However, if you want a picture:

tree -P "*foo"

Hope this helps!

If your shell supports a new globbing option (can be enabled by: shopt -s globstar), you can use:

echo **/*foo*

to find any files or folders recursively. This is supported by Bash 4, zsh and similar shells.

Personally I've got this shell function defined:

f() { find . -name "*$1*"; }

Note: Above line can be pasted directly to shell or added into your user's ~/.bashrc file.

Then I can look for any files by typing:

f some_name

Alternatively you can use a fd utility with a simple syntax, e.g. fd pattern.

Following command will list down all the files having exact name "pattern" (for example) in current and its sub folders.

find ./ -name "pattern"

I am surprised to see that locate is not used heavily when we are to go recursively.

I would first do a locate "$PWD" to get the list of files in the current folder of interest, and then run greps on them as I please.

locate "$PWD" | grep -P <pattern>

Of course, this is assuming that the updatedb is done and the index is updated periodically. This is much faster way to find files than to run a find and asking it go down the tree. Mentioning this for completeness. Nothing against using find, if the tree is not very heavy.

If you want to search special file with wildcard, you can used following code:

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

Suppose, you want to search every .conf files from here:

. means search started from here (current place)
-type means type of search item that here is file (f).
-name means you want to search files with *.conf names.

Below command helps to search for any files

1) Irrespective of case
2) Result Excluding folders without permission
3) Searching from the root or from the path you like. Change / with the path you prefer.

Syntax :
find -iname '' 2>&1 | grep -v "Permission denied"


find / -iname 'C*.xml' 2>&1 | grep -v "Permission denied"

find / -iname '*C*.xml'   2>&1 | grep -v "Permission denied"

Try with fd command if installed. Install instruction

find all file starts with 'name'

fd "name*"

This command ignores all .hidden and .gitignoreed files.

To include .gitignoreed files, add -I option as below

fd -I "name*"

To include hidden files, add -H option as below

fd -H "name*"

With Python>3.5, using glob, . pointing to your current folder and looking for .txt files:

 python -c "import glob;[print(x) for x in glob.glob('./**/*txt', recursive=True)]"

For older versions of Python, you can install glob2
