8: Syntax error: word unexpected (expecting ")")

Question

The following code:

weekday=$(date +%a) day=$(date +%d) month=$(date +%m) if [[ ( $month == 03 || $month == 10 ) && $weekday = "Sun" && $day > 24 ]] then # DO SOMETHING exit 1 else # DO SOMETHING fi 

leads to the error:

 8: Syntax error: word unexpected (expecting ")") 

when executing with:

/bin/sh script.sh 

What is wrong here and how can this be fixed?

I need to use sh how i need to modificate this code to get working with sh?

Answer 1

weekday=$(date +%a) day=$(date +%d) month=$(date +%m) if [ \( \( $month -eq 03 \) -o \( $month -eq 10 \) \) -a \( "$weekday" = "Sun" \) -a \( $day -gt 24 \) ] then # DO SOMETHING echo ok else # DO SOMETHING echo ko fi 

Answer 2

The correct way is:

weekday=$(date +%a) day=$(date +%d) month=$(date +%m) if { [ $month -eq 03 ] || [ $month -eq 10 ]; } && [ $weekday = "So" ] && [ $day -gt 24 ] then echo "true" else echo "false" fi
