defining a 3rd (and fourth) if statement

aristosv · 08-14-2015, 11:25 AM

I am using the script below to play music from predefined folders. If it's a week day I play from $morning folder and if it's a weekend I play from $weekend folder.

Quote:

if [[ $(date +u) -lt 6 ]] ; then
/usr/bin/mpg123 -Z -q -f $volume $morning/* &
else
/usr/bin/mpg123 -Z -q -f $volume $weekend/* &
fi

I need to somehow play music from $evening folder, only if its after 3pm and only if its a weekday.

Can I get some help on doing that?

Thanks.

You ought to be able to use a nested if. Something like this:

Code:

#!/bin/bash

# Check if weekday or not
if [[ $(date +u) < 6 ]]; then
    if [[ $(date +%H) > 15 ]]; then
        echo "A weekday after 3pm (15:00 hours)."
        echo "Play from evening directory"
    else
        echo "A weekday before 3pm (15:00 hours)"
    fi  
else
    echo "Play from weekend directory"
fi

Upon execution (now, at fri 14 aug 2015 19:06:25 CEST), I get this result:

Code:

$ ./check_day_time.sh 
A weekday after 3pm (15:00 hours).
Play from evening directory

If I simulate -7 hours:

Code:

#!/bin/bash

# Check if weekday or not
if [[ $(date +%u) < 6 ]]; then
    #if [[ $(date +%H) > 15 ]]; then
    if [[ $(date -d '7 hour ago' "+%H") > 15 ]]; then
        echo "A weekday after 3pm (15:00 hours)."
        echo "Play from evening directory"
    else
        echo "A weekday before 3pm (15:00 hours)"
    fi  
else
    echo "Play from weekend directory"
fi

I get this result.

Code:

./check_day_time.sh 
A weekday before 3pm (15:00 hours)

And finally, if I simulate a weekend:

Code:

!/bin/bash

# Check if weekday or not
#if [[ $(date +%u) < 6 ]]; then
if [[ $(date -d '+1 day' "+%u") < 6 ]]; then
    #if [[ $(date +%H) > 15 ]]; then
    if [[ $(date -d '7 hour ago' "+%H") > 15 ]]; then
        echo "A weekday after 3pm (15:00 hours)."
        echo "Play from evening directory"
    else
        echo "A weekday before 3pm (15:00 hours)"
    fi  
else
    echo "Play from weekend directory"
fi

I get this result:

Code:

$ ./check_day_time.sh 
Play from weekend directory
