hi all
i have a folder "images".
it contains a lot of images/files.
how to know the number of images/files in that folder.

find /path/to/images/folder -type f | wc -l

If its just the one single level dir,

ls|wc -l

thank you. it is very helpful

I have taken clue from previous post & come up with simplest way

Finding number of files in a folder
find . -type f | wc -l
this means output of find comand (which is only files no directories)is sent to wc which counts number of lines i.e number of files

Finding number of subfolders in a folder
(1)find . -type d | wc -l
This will give number of subfolders+1 because current folder also gets included.Note that the folders inside subfolders are also included in count.
(2)If you want to see only number of folders in current folder then
find . -maxdepth 1 -type d | wc -l
Here output is numberof subfolders+1
NOTE:folders inside subfolders not considered.

If this information helps you please thank me by pressing thumbs up button.Happy hacking.

It work well. Thanks for your support !
