Help with Date Variable
Hi all,

Am flustered up with date... interesting what I had used to work in Fedora 4 and now with a system update to fedora 10 it doesn't and really not sure why?

I assign a variable: date_log=`date -d '1 day ago' +"%h %e"` which is for a specific system log that uses dates in format "Feb 5" losing the leading 0's. So I used this for about 2 years on fedora 4 by setting up log collections for last 10 days using the string format assigned to a variable, passed that to a function and grep'd out some stuff by day.

Now with fedora 10 bash strips the leading extra space after it puts it in the variable.

This works: foo=`date +"%h %e"` foo shows "Feb 5" with two spaces
this does not: foo=`date -d '1 day ago' +"%h %e"` foo shows "Feb 5" with one space. I can type the same date command at CLI and it shows two spaces. Interesting it worked fine in fedora 4??

Actual code truncated:
Code:
	case $menuDate in
	"1")	data_date=`date +%Y%m%d`
			data_date_log=`date +"%h %e"`
			data_date_dec=`date +%m%d`
			GetData ;;
	"2")	data_date=`date -d '1 day ago' +%Y%m%d`
			data_date_log=`date -d '1 day ago' +"%h %e"`
			data_date_dec=`date -d '1 day ago' +%m%d`
			GetData ;;

Get data simply greps out some dates such as:
Code:
grep "$data_date_log" $DIR3/errorlog.txt > /usb/$site'_'$data_date/$errorlog'_'$data_date.txt

Really confused why the space is now truncated.

I tried assigning the variable in quotes like date="$(date -d '1 day ago' +"%h %e")"

Tried using %b %_d as the format.

I can always get date to respond properly with appropriate formatting, but once I shove it into a variable the space goes away.

Idea's?

Thanks a bunch!
