List Files by Extensions - UNIX for Dummies Questions & Answers

newbienix · #1 (**permalink**) 05-24-2006

I have a unix directory with 500 plus files . When I do a ls -lR I can see ALL the files here . How can I sort this by the files extensions ?

I can't enter ls -lR *.ext1 *.ext2 *.ext3 etc in case I miss out some files .

Specify delimiter for sort as period(.) and sort based on the second key.

Code:

ls -lR | sort -t. -k 2

This assumes your filenames donot have any period(.) inbetween their names.

Yes ! It works now . Have sorted those 500+ files by extensions

Thanks
