Hi, what is your OS?

If you have GNU date you could do:
Code:
date -d"last month" +%b%y

or
And if you then also have a recent ksh93 you could use:
Code:
printf "%(%b%y)T\n" "last month"

Try:
Code:
perl -MPOSIX -sle '@t=localtime; $t[4]-=1 ; print strftime("%b%y",@t)'

or:
Code:
perl -MPOSIX -sle '@t=localtime; $t[4]-=$m ; print strftime("%b%y",@t)' -- -m=1


--
EDIT:

This does not work reliably when $t[4]-=1 is not a valid date..
Instead try:

Code:
perl -MPOSIX -sle '@t=localtime; $t[4]-=1 ; $t[3]=15; print strftime("%b%y",@t)'

or
Code:
perl -MPOSIX -sle '@t=localtime; $t[4]-=$m ; $t[3]=15; print strftime("%b%y",@t)' -- -m=1

Like so?
Code:
NewLogDirName=$(perl -MPOSIX -sle '@t=localtime; $t[4]-=1 ; print strftime("%b%y",@t)')

I noticed you used %d%b%Y though? Then use [ICODE]"%d%b%Y"[/ICODE] instead of [ICODE]"%b%y"[/ICODE]

--EDIT:--
That should be
Code:
perl -MPOSIX -sle '@t=localtime; $t[4]-=1 ; $t[3]=15; print strftime("%b%y",@t)'
