How to count files

To count how many files for each extension are present in a path, you can use one of the answers of "Count files in a directory by extension" question of another site[1], e.g.:

ls | awk -F . '{print $NF}' | sort | uniq -c | awk '{print $2,$1}'

How to list grouped by extension

To group the files by extension you can use simply the -X option of ls

ls -X

--sort=WORD
          sort by WORD instead of name: 
          none -U, extension -X, size -S, time -t, version -v

Note:

  • The concept of extension is imported from DOS, under Unix there is only the file name eventually with more than one '.' character inside...

If I understand your question, you can use this command -

ls -ls | awk '{print $10}' | grep "\." | awk -F. '{print $2}' | sort | uniq -c

which count the extensions in the current path.
