[TriLUG] BASH oddity

[Paul G. Szabady]

Greetings,

I'm trying to write a script and find something confusing.  If you look at
the examples below, I was using #2.  It works if I manually set it to '8',
but not '08'.  It works with both '6' and '06'.

So, what's special about '08'?

#1
[paul at at paul]$ declare -i dirx=$(date +%g)
[paul at at paul]$ echo $dirx
6


#2
[paul at at paul]$ declare -i dirx=$(date +%V)
-bash: declare: 08: value too great for base (error token is "08")
[paul at at paul]$ echo $dirx
6


#3
[paul at at paul]$ declare -i dirx=08
-bash: declare: 08: value too great for base (error token is "08")
[paul at at paul]$ echo $dirx
6


#4
[paul at at paul]$ declare -i dirx=8
[paul at at paul]$ echo $dirx
8


#5
[paul at at paul]$ declare -i dirx=06
[paul at at paul]$ echo $dirx
6



[paul at at paul]$ export thisweek=(date +%g) ; echo $thisweek
(date +%g)
[paul at at paul]$ export thisweek=$(date +%g) ; echo $thisweek
06
[paul at at paul]$ export thisweek=$(date +%V) ; echo $thisweek
08
[paul at at paul]$
