Shell Programming and Scripting

Hi,

How to write the recursive function.

I have a script,

Code:

#!/usr/bin/ksh
##
name=$1
outputfile='output.log'
sqlplus -s > ${outputfile} <<__END__
${USER}/${PASS}@${DB}
WHENEVER SQLERROR EXIT SQL.SQLCODE ROLLBACK
WHENEVER OSERROR EXIT FAILURE ROLLBACK
SET ECHO ON
SET SERVEROUTPUT ON SIZE 1000000
select count(*)  FROM table WHERE date = '$curdate'  and name='$name';
EXIT
__END__

exec >> $logfile 2>&1
echo "HI" > $logfile
/bin/mail -s "$SUBJECT" "$EMAIL" < $logfile

I have to run the script at 1,2,6,7 AM everyday without using crontab.
How to use the sleep command at regular intervals and runs it everyday and specific time

./abc.sh ABC should run at 1.10 AM

./abc.sh DEF should run at 2.30 AM

./abc.sh EFG should run at 6.10 AM

./abc.sh HJI should run at 7.22 AM

---------- Post updated at 01:10 AM ---------- Previous update was at 12:54 AM ----------

I am writing this in a separate shell script wrapper.sh
How to make the script till 1.10AM and how to add the condition like this

[Sleep till 1.10 AM and execute]
./abc.sh ABC should run at 1.10 AM
sleep 1 hour 20 min
./abc.sh DEF should run at 2.30 AM
sleep another 3 hours,40 min
./abc.sh EFG should run at 6.10 AM
sleep for 1 hour 12 min
./abc.sh HJI should run at 7.22 AM
sleep for 17hours

Hi

Check this geekstuff link usage of 'at' command: at atq commands (link removed)


Guru.

at -f ./abc.sh ABC now + 1 min
syntax error. Last token seen: A

In the script, I used the command with paramerter. ABC is the argument.

i can write a script for every day but this must be always working in background and is not never like crontab daemon..
according to me you may be use cron

for at command may be use this in your script add last line in your script

let try like this

Code:

 
wtime="13:10" #pm
parameter=ABC
script="./a.sh"
at now + 1 min <<<"$script ABC"
