You can use the if command with the test command to check if the string matches a specific criterion:
- if [$string1 = $string2]: This checks if string1 is identical to string2
- if [$string1 != $string2]: This checks if string1 is not identical to string2
- if [$string1 \< $string2]: This checks if string1 is less than string2
- if [$string1 \> $string2]: This checks if string1 is greater than string2
The less than and greater than should be escaped with a backslash as if it shows a warning.
- if [-n $string1]: This checks if string1 is longer than zero
- if [-z $string1]: This checks if string1 has zero length
Let's see some examples to explain how if statements work:
#!/bin/bash if [ "mokhtar" = "Mokhtar" ] then echo "Strings ...
