IF With Number
We can use IF with the test command.
#!/bin/bash
number=5
if test $number -eq 5
then
echo "number is euqal to five"
fi
instead of test command, we can use its alias that is [.
- eq use for equals operations.
- lt is used for less than.
- gt is used for greater then
- le is used for less than or equal.
- ge is used for greater than or equal.
- ne is used for not equal.
#!/bin/bash
number=15
# eq is for equal, if number is equal to 5 then the below condition will become true.
if [ $number -eq 5 ]
then
echo "number is eq 5"
fi
# lt is for less then, if number is less than 11 then the below condition will become true.
if [ $number -lt 10 ]
then
echo "number is less than 10"
fi
# gt is for greater then, if number is greater than 4 then the below condition will become true.
if [ $number -gt 4 ]
then
echo "number is greater then 4"
fi
# ge is for greater then or equal, if number is greater than or equal to 5 then the below condition will become true.
if [ $number -ge 5 ]
then
echo "number is grater than or equal to 5"
fi
# le is for less then or equal, if number is less than or equal to 5 then the below condition will become true.
if [ $number -le 5 ]
then
echo "number is less than or equal to 5"
fi
# ne is for not equal, is number is not euqal to 5 then below condition will become true.
if [ $number -ne 5 ]
then
echo "number is not equal to five."
fi
