In this article we will provide you a bash script code with live demo to check if a substring is present at the end of a string or array. We will also see the code for conditions when substring is not at the end.
Code Example –
1. Check if substring is at the end of string –
#!/bin/bash
var="This is a string"
if [[ $var == *ing ]]; then
printf '%s\n' "var ends with sub_string."
fi
# Output:
# var ends with sub_string.
2. Check if substring is NOT at the end of string –
#!/bin/bash
var="This is a string"
if [[ $var != *str ]]; then
printf '%s\n' "var does not end with sub_string."
fi
# Output:
# var does not end with sub_string.
3. Check if substring is at the end of array –
#!/bin/bash
arr=("This" "is a" "string")
if [[ ${arr[*]} == *ing ]]; then
printf '%s\n' "sub_string is at end of array."
fi
# Output:
# sub_string is at end of array.
4. Check if substring is NOT at the end of array –
#!/bin/bash
arr=("This" "is a" "string")
if [[ ${arr[*]} != *str ]]; then
printf '%s\n' "sub_string is not at end of array."
fi
# Output:
# sub_string is not at end of array.
