Formatting dates to a specific pattern
Hello, I need to format the current date (as returned by date(1) ) to the pattern m-d-, where m is the month in one or digits, d is the day in one or two digits, and is the year in four digits. The problem for me is the day and the month, for example August should be 8, and not 08, and 5th of September should be 9-5-2008 and not 09-05-2008. I read the man page of date(1) but date(1) seems to always put leading zeros. I appreciate any help on how to format the date the way I want. In case you wonder why I need such a format: I am using a hosting company to run a web site. They are backing up my files in a .tar.gz archive and I can download it. The name of the backup archive contains the date formatted as I explained. I want to write a daily cron job script that will download the backup for me.

hello rambius!
you can give this script a try - it seems to do what you want and
has comments too. save it as de0.sh, chmod +x it and run it as
./de0.sh `date +%m-%d-%Y`
(there are no doubt better ways to do what you want especially if you
use a more advanced shell like zsh, but this may be sufficient)
==
#!/bin/sh
# removes 0 from mm-dd-
# run with ./de0.sh `date +%m-%d-%Y`
#the whole date from argument $1
mmdd=$1
#get the year
=${mmdd##*-}
#get the month and day
mmdd=${mmdd%-*}
#get the day
dd=${mmdd#*-}
#get the month
mm=${mmdd%-*}
#remove 0 if only at beginning of month, day and add on the year
echo ${mm#0}-${dd#0}-$

Re: Formatting dates to a specific pattern
I need to format the current date ... to the pattern m-d- ... date(1) seems to always put leading zeros. # date +%m-%d-%Y | sed 's/^0//g' 8-30-2008 Not quite. That fixes the month, but not the day: $ echo 02-04-2008 | sed 's/^0//g' 2-04-2008 (The g does nothing, because the ^ can match only at the beginning of a line.) This does both: $ echo 02-04-2008 | sed -e 's/^0//' -e 's/-0*/-/' 2-4-2008 ___ freebsd-questions@freebsd.org mailing list http://lists.freebsd.org/mailman/listinfo/freebsd-questions To unsubscribe, send any mail to [EMAIL PROTECTED]
Re: Formatting dates to a specific pattern
Hello, Thank you for all of your responses. I received earlier a private answer from another member of list. He told me to use the '-' sign after '%' in the date pattern of date(1) command: $ date +%-m%-d%Y This one seems to not include leading zeros and I reworked it to $ date +%-m-%-d-%Y to fit my needs :) Regards Rambius -- Tangra Mega Rock: http://www.radiotangra.com ___ freebsd-questions@freebsd.org mailing list http://lists.freebsd.org/mailman/listinfo/freebsd-questions To unsubscribe, send any mail to [EMAIL PROTECTED]
