Assuming the stat command on your system allows for the -f (--file-system) option, and shamelessly stealing from Don Cragun's earlier post, and NOT being able to ultimately test this on my system, I'd propose this (printing some meaningful numbers for debug purposes) and ask you to comment back:
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,
I have tested your code . do you see if your wonderful solution to on right track to reach my goal). Its lot of pain to duplicate files and renamed it correctly to make sure it crosses 70% of discspace (as this is test vm) By the way, if every thing looks good, where I need to place actual rm command
So after every echo, the printed line is number of blocks to be removed ?.. I think file wise it showing first 3 files based on names marked for deletion..thats good.. I think i am almost there what I need.. Thank you very much.. Awaiting your comments.
