increase time by n minutes

[ogniemi]

hello,

begin hour is 00:00

I need to increase it by 5 minutes in loop to get:

00:05
00:10
00:15
...
...
23:50
23:55


Thank you in advance,
r.m.

2 nested loops perhaps?

Like this using
man seq for details

#! /bin/ksh
for HH in $(seq 0 23)
do
        for MN in $(seq 0 5 55 )
        do
                printf "%.2d:%.2d\n" $HH $MN
        done
done

Hi

You not specified your shell. If it is [tt]bash[/tt] :

echo {[purple]00[/purple][teal]..[/teal][purple]23[/purple]}[teal]:[/teal]{[purple]00[/purple][teal]..[/teal][purple]59[/purple][teal]..[/teal][purple]5[/purple]}

Tested with [tt]bash[/tt] 4, in older versions not works. See Brace Expansion in [tt]man bash[/tt] for details.

Sorry, I need something for ksh.

if you don't have seq:

[tt]hh='0 1 2 4 3 5 6 7 8 9 10 11 12 13 14 15 16 17 18 19 20 21 22 23'
mm='0 5 10 15 20 25 30 35 40 45 50 55'
for h in ${hh}
do
for m in ${mm}
do
time=$(printf "%02d:%02d\n" ${h} ${m})
echo $time
done
done[/tt]

Wait for 00:00:00 and start:

for (( i=0; i<$((24*12)); ++i )); do date +%M:%S ; sleep 5; done

Note: it will run in 24 minutes, not hours! Very efficiently!

Seems to work in ksh too.
