How to find string of file name of images?
Hi & good day,

How to use find correctly ?

I have several folders, _img1, _img2 etc.

Then I want to use the find command to find part of an image name, such as:

the string ”modern”

which is (at least) in:

”_img2/modern_world2PS220.jpg”

Also I want to know _in which folder_ it was found.

This does not work:
Code:
find . -type f -print modern *

Any ideas please?

with best regards,

Hello OmarKN,
If you are looking for strings within a file, then have a look at the grep command. It allows you to search within files for expressions or strings. It is often combined with find so that one finds a list of files matching on name, location, age etc. and then it repeatedly calls grep to search within those files.


I hope that this helps, but feel free to ask for more information if I'm not clear or I have gone off on the wrong direction.

Alternatively,

How to restrict the search to only certain folders? (such as _img1/ _img2/ )?

Hi Robin,

This was interesting.

Do you think you have an example as to first use find (a string in a file name) and then also grep (inside the file)?

That would be great!

Hello Omkar,

Here is the example as per your request, I am just using mtime which will look for files which are older than a day and then I am looking for a text in those files just for example.
Kindly let me know if this helps.


let us say we have following files in our test directory.

Code:
-rw-rw-r--. 1 singh singh   0 Aug 15 13:25 new file
-rw-rw-r--. 1 singh singh  74 Aug 18 10:44 check_data
-rw-rw-r--. 1 singh singh 136 Aug 19 09:10 get_data1211
-rw-rw-r--. 1 singh singh  81 Aug 19 09:26 get_data1211.ksh

Code:
find . -mtime -1 -type f -exec grep -i "chr1" {} \;

Output will be as follows.

Code:
chr1    3217769    3217789    2952725-5    255    +
chr1    3260455    3260475    2434087-6    255    -

Thanks,
R. Singh

You can restrict jpg and png files like this

Code:
find  -type f -name "*modern*.jpg" -o -name "*modern*.png"

2. find _img1/ _img2/ ...
