Shell Programming and Scripting

Hi.

First of 17 million hits from Google search for linux sequence of dates display OR compute: unix - How to generate a sequence of dates given starting and ending dates using AWK of BASH scripts? - Stack Overflow

You'll need to do work on those selections to create a list similar to that from dateutils.dseq.

Best wishes ... cheers, drl

we are currently on Redhat linux 6.5..The command apt-get install date-utils asked for execution is for Ubuntu Linux.

Hello tradingspecial,

Could you please check following script and let me know if this helps you.

Code:

cat script.ksh
PWD=`pwd`
OUT_FILE=$PWD"/output_file"
ZERO=0
if [[ -f $OUT_FILE ]]
then
        echo "Run script here."    ####You could call you script/command here.
        rm $OUT_FILE
        exit;
fi
VAL=`cal 12 2016 | awk -vout_file="$OUT_FILE" 'NR>2{for(i=1;i<=NF;i++){if(($i==2 || $i==4 || $i==7) && (i==7 || i==1)){print $i " of this month is falling on a working day." > out_file;print 1} else {print 0}}}'`
 
if [[ $VAL == $ZERO ]]
then
        echo "Run script here."   ####You could call you script/command here.
fi

So following things also should be done by you apart from above code.
i- Create a script(as above shown) with proper permissions.
ii- Schedule an entry in cronby doing crontab -e.
iii- Entry should be like that so it should run that script for each month from dates 1 to 8.
It could be like as follows, where I am running script from each month's 1st to 8th date on 1 AM of your box timing.

Code:

0 1 1-8 * * /path/to/exact/script.ksh

iv- Also in above code I have tested it with command cal 12 2016 because it has 2nd of October falling on Sunday, you could change it to cal in above code.
A big disclaimer here, I haven't tested it at all, this goes to your plate, please do proper testing and get back to us then.

Thanks,
R. Singh
