A newbie with a problem in A date Script
Hello everybody...
I'm a Unix newbie and i just got this task at work to figure out what's wrong with a daily script my team is using.
The idea behind the script is that it takes the day before in a
yyyymmdd format, find files with that date in a specific directory and executes an (irrelavant) operation on them.
The problem with the script is that it won't work in every 1st of every month. So in every 1st of each month they need to change the script manualy.
I think that it has to do with the $d-1 section so in eache 1st of the month it thinks that the day before is 0.
My task is to figure out a way to change the script so it will work every day of the month including the 1st of every month.
It's my first day on a new job and i dont know anything about scripting so please be gentle. I'd appreciate it if you could find a way to correct it and explain it to me.
The relevant lines are these:
d=`date '+%d'`
d=`/usr/bin/expr $d - 1`
if [ $d -lt 10 ]
then
DATE=`date '+%Y%m'`0$d
else
DATE=`date '+%Y%m'`$d
fi
DATE='20060831'
cd ${root_dir}
num=`ls -1 dec_${DATE}*|wc -l`>/dev/null
if [ $num -lt 21 ]
#if [ $num -lt 1 ]
then
Plz help...
Thx in advance !!!!

accounting
ACCOUNTING(1) SMPPPD ACCOUNTING(1)
NAME
accounting - calculates statistics about your internet connections
DESCRIPTION
accounting is a simple program to calculate statistics about your internet dial-up connections that are started and stopped by either ifup
and ifdown or by a frontend to smpppd like cinternet , qinternet or kinternet.
OPTIONS
These options are recognized by accounting. If a long option shows an argument as mandatory, then it is mandatory for the equivalent short
option also.
-l, --last=NUM
Only consider the last NUM connections.
-a, --after=DATE
Only consider connections started after DATE. DATE is a date with optional time in ISO 8601 format, e.g. `2002-12-24 20:15:00'.
Note that a date without time is treated as if the time is 00:00:00. Hence connections started on the specified date are consid-
ered.
-b, --before=DATE
Only consider connections started before DATE.
-u, --user=USER
Only consider connections started by user USER.
--this-year
Only consider connections started this year.
--last-year
Only consider connections started last year.
--this-month
Only consider connections started this month.
--last-month
Only consider connections started last month.
--this-week
Only consider connections started this week.
--last-week
Only consider connections started last week.
--today
Only consider connections started today.
--yesterday
Only consider connections started yesterday.
--per-year
Show summaries on a per year basis.
--per-month
Show summaries on a per month basis.
--per-week
Show summaries on a per week basis.
--per-day
Show summaries on a per day basis.
-c, --connections
Only list the connections but do not show provider statistics.
-p, --providers
Do not list the connections only show the provider statistics.
--connection-format=FORMAT
The names of the columns to print in the connection list. The names must be separated by a comma. Known column names are time,
type, provider, user, status, duration, rx, tx, rxtx, averx, avetx and averxtx. Each name may be appended by a colon and a number
indicating the width for the column, e.g. provider:25. The value will not be truncated if the width is too small.
--provider-format=FORMAT
The names of the columns to print in the provider list equivalent to the --connection-format option. Known column names are
provider, number, duration, rx, tx, rxtx, aveduration, averx, avetx and averxtx.
--local
Display all dates in local time. Also interpret dates on the command line in local time. This is the default.
--utc Display all dates in UTC. Also interpret dates on the command line in UTC.
--script[=STYLE]
Format output for script. Known styles are c and sh.
-f, --file=NAME
Use a different file with accounting information.
--report-errors
Report erros in the accounting file.
--version
Show program version and exit.
--help Show help information and exit.
NOTES
All informations are only obtained through the accounting log. Hence the informations, esp. the data volume, of currently active connec-
tions is not accurate. If you want the know the status of a connection, use ifstatus or a frontend to smpppd like cinternet , qinternet or
kinternet instead.
The user field is empty for connections started by a remote frontend of smpppd.
BUGS
Not yet implemented for ISDN (ippp).
FILES
/var/log/smpppd/accounting.log
File containing accounting information.
SEE ALSO
