Hello I am trying to implement simple if statement in linux script however after executing it I get an error : [6: command not found - 6 is the number from input
I added chmod +x and execute it : ./script

#!/bin/bash

echo "input number"
read number

if [$number>5]
then echo "number greater than 5"
fi

Spacing is important: `if [ $number>5 ]`. – James Brown Nov 18 '20 at 08:59

Operators are important too. `>5` would redirect to a file named `5`. – KamilCuk Nov 18 '20 at 09:01
should I use -gt then instead of > ? – fluffy Nov 18 '20 at 09:05
Yup I tried it my scirpt print sth but at the same time I get an error no such file or directory when I changed it to -gt it works 100% fine now thanks – fluffy Nov 18 '20 at 09:08

For integer comparison you should use `-gt`, > should be used for string comparison and should be escaped `\>`. – vsergi Nov 18 '20 at 09:08
