How to remove filenames having the same extension.?
hi,

i have a directory which contains some files and a subdirectory. i am writing only the files names to a file using the below code.
Code:
ls -ltr | grep "^-" | awk '{print $NF}' > /home/file_list$$

Code:
cat /home/file_list$$
s1_abc.txt
s2_def.xls
s3_def.xls

as you can see there is one .txt file and 2 .xls file.
i want to keep any one file for each extension. i.e i want to have unique file for each extension. so the
Quote:
file_list$$
will have only the following contents
Code:
s1_abc.txt
s2_def.xls

how can i do this?
