Adding spaces among two or more variables ....

[Manuales]

hi ..

this is the code in question:
a=`perl -MPOSIX -le 'print strftime "%b %d",localtime(time-86400)'`
echo valor de a $a
case `echo $a | cut -d" " -f2 | cut -c1 | sed 's/ //g'` in
"0" ) echo estoy adentro del case; mm=`echo $a | cut -d" " -f1`
dd=`echo $a | cut -d" " -f2 | cut -c2`; esp=" " ; b="$mm$esp$dd" ;;
esac


$ ./printers_in_use.sh
value of a: May 01
estoy adentro del case
esto vale ahora b: May 1

how can i do?
i need b appears as follows: May 1 (with two spaces between May and 1)

please let me kow.
thanks.

Hi Manuales:

> need b appears as follows: May 1 (with two spaces between May and 1)

You use this:

# perl -MPOSIX -le 'print strftime "%b %e",localtime(time-86400)'

That is, change the "%d" to a "%e" just as the manpages for 'date' would show you.

I did that
but i need "two spaces" not one ...
$ a=`perl -MPOSIX -le 'print strftime "%b %e",localtime(time-86400)'`
$ echo $a
May 1
$

how can i do it?

Im sorry
this is the correct script:

a=`perl -MPOSIX -le 'print strftime "%b %e",localtime(time-86400)'`
echo valor de a $a
case `echo $a | cut -d" " -f2 | cut -c1 | sed 's/ //g'` in
"0" ) echo estoy adentro del case; mm=`echo $a | cut -d" " -f1`
dd=`echo $a | cut -d" " -f2 | cut -c2`; esp=" " ; b="$mm$esp$dd" ;;
esac

$ a=`perl -MPOSIX -le 'print strftime "%b %e",localtime(time-86400)'`
$ echo $a
May 1

i need two spaces instead of one in "May 1"

Hi (again) Manuales:

> $ a=`perl -MPOSIX -le 'print strftime "%b %e",localtime(time-86400)'`
> $ echo $a

The Perl is now correct, but your 'echo' is NOT. You need to double quote the variable you echo to preserve multiple spaces:

# echo "$a"

$ a=`perl -MPOSIX -le 'print strftime "%b %e",localtime(time-86400)'`
$
$ echo "$a"
May 1
