Date Range in UNIX
Hi Everyone How all are doing today, Want some help from All in Unix, What I am trying to do is , A shell file should be a called with two date parameters suppose the shell file name is run.sh run.sh <start_date> <end_date> If end date is not given it will pick today's date. The date should be in format yyyy-mm-dd. Now the twist is suppose I have given the dates Code:
run.sh 2012-01-01 2012-01-30 Inside this shell file It should pick the data range max of 6 days from start date like at first hit the Start date and end date should be 2012-01-01 and 2012-01-07 #- 6days and print on the screen at second hit the Start date and end date should be 2012-01-07 and 2012-01-13 #- 6days .. . . . . at last hit the Start date and end date should be 2012-01-25 and 2012-01-30 #- 6days .. I hope I am able to clear you Thanks |

Using the ksh93 shell ... Code:
#!/bin/ksh93
nextdate=$(printf "%(%s)T" "$1")
enddate=$(printf "%(%s)T" "$2")
typeset -i DAY=24*60*60
while (( nextdate < enddate ))
do
printf "%(%Y-%m-%d)T" "#${nextdate}"
for ((i=1; i < 7 && 0 == $(( (nextdate + $DAY) > enddate )); i++))
do
(( nextdate += $DAY ))
done
printf " %(%Y-%m-%d)T\n" "#${nextdate}"
doneproduces Code:
$ ./run.sh 2012-01-01 2012-01-30 2012-01-01 2012-01-07 2012-01-07 2012-01-13 2012-01-13 2012-01-19 2012-01-19 2012-01-25 2012-01-25 2012-01-30 $ |

If you have
GNU date Code:
#!/bin/bash
DT1=$1
DT2=$2
E_DT1=$( date -d"$DT1" +"%s" )
E_DT2=$( date -d"$DT2" +"%s" )
while [ $E_DT1 -lt $E_DT2 ]
do
printf "%s " $( date -d@"$E_DT1" +"%Y-%m-%d" )
DT1=$( date -d"$DT1 +6 days" +"%Y-%m-%d" )
E_DT1=$( date -d"$DT1" +"%s" )
[[ $E_DT1 -le $E_DT2 ]] && printf "%s\n" $( date -d@"$E_DT1" +"%Y-%m-%d" ) || printf "%s\n" $( date -d@"$E_DT2" +"%Y-%m-%d" )
