Code:

{ cd /backup; stat -fc"%b %a %S" .; stat -c"%n %b %B" 2018*.tar.gz | sort; } | awk '
NR == 1         {print Needed = ($1 * PCT - $2) * $3 
                 next
                }

                {split ($1, T, "_")
                 if (T[1] == KnownTime) print "echo rm " LastFile
                 KnownTime = T[1]
                 LastFile = $1
                 print SUM += $2 * $3
                 if (SUM >= Needed) exit
                }
 ' PCT=0.4

Once happy with what is delivered, we can pipe this into an sh command to be executed.

Hi RudiC,

Thankyou very much for snippet, shall try it on different test machine, sorry for dumb question, which line one specifies 60 % as thread hold...I wanted to test on a sample % as threshold on test machine. because test machine i have 10 gb of these tar files
