Unselect Files ---need help

[arz_razi]

Hi.. I have a problem on filtering the data in unix

The files is
         abc.done
         gba.done  
         a.txt
         c.txt
         b.sh
         <any file that doesnt have .done extension>

How can is select all the files without selcting the file that have extension of .done .
How can is use 'll or ls' command to unselect .done data.

$ll -lrt <to unselect .done data>

Please help me as i'm new in UNIX envoirement.
Thank YOu

If your ls version have a --hide option,

Code: [Select]

ls -ltr --hide=*.done

or you can use combination of ls and grep

Code: [Select]

ls -ltr |grep -v ".done"

or you can use find command

Code: [Select]

find . -maxdepth 1 -not -name "*.done" #find only current directory
