Menu
Open File Explorer; if you do not have an icon for this in the task bar; click Start, click Windows System, and then File Explorer. Click the View tab in File Explorer. Click the box next to File name extensions to see file extensions.
Folder extensions are . dir . If you right-click a folder and go to Properties > General, it says Type: File Folder (. dir).
To sort files in a different order, click one of the column headings in the file manager. For example, click Type to sort by file type. Click the column heading again to sort in the reverse order.
To find out file types we can use the file command. Using the -s option we can read the block or character special file. Using -F option will use string as separator instead of “:”. We can use the –extension option to print a slash-separated list of valid extensions for the file type found.
Try this (not sure if it's the best way, but it works):
find . -type f | perl -ne 'print $1 if m/\.([^.\/]+)$/' | sort -u
It work as following:
No need for the pipe to sort, awk can do it all:
find . -type f | awk -F. '!a[$NF]++{print $NF}'
Recursive version:
find . -type f | sed -e 's/.*\.//' | sed -e 's/.*\///' | sort -u
If you want totals (how may times the extension was seen):
find . -type f | sed -e 's/.*\.//' | sed -e 's/.*\///' | sort | uniq -c | sort -rn
Non-recursive (single folder):
for f in *.*; do printf "%s\n" "${f##*.}"; done | sort -u
I've based this upon this forum post, credit should go there.
My awk-less, sed-less, Perl-less, Python-less POSIX-compliant alternative:
find . -type f | rev | cut -d. -f1 | rev | tr '[:upper:]' '[:lower:]' | sort | uniq --count | sort -rn
The trick is that it reverses the line and cuts the extension at the beginning.
It also converts the extensions to lower case.
