Change numbers to random letter in SED
.everyoneloves__top-leaderboard:empty,.everyoneloves__mid-leaderboard:empty,.everyoneloves__bot-mid-leaderboard:empty{ margin-bottom:0;
}
Considering the following number: 145478
I want to replace these numbers with random letters from a to z.
My attempt so far: sed -r 's/[0-9]/[a-z]/g'
It does not change the pattern to another pattern but exactly whatever I typed in the second place.
The result I got is: [a-z][a-z][a-z][a-z][a-z][a-z]
How do I make it into an actual pattern? In other words, how do I turn these numbers into random letter?

Not an awk or sed solution, but I hope this helps anyway. Are the same numbers always supposed to be replaced by the same letters? If not:
perl -pe 's/[0-9]/chr 97+rand 26/eg' input.txt
If they are, then this is one solution:
perl -MList::Util=shuffle -M5';$x=join"",shuffle a..z' -pe 'eval"tr/0-9/$x/"' input.txt
Update: For shorter versions of the second one, see this thread.
