To extract the third field separated by forward slash (/) delimiter in Unix/Linux shell, you can use the following command:
echo "field1/field2/field3/field4" | awk -F'/' '{print $3}'
This uses the awk command to split the input string on forward slashes (/) and then prints the third field ($3). The -F option is used to specify the field delimiter.
You can replace "field1/field2/field3/field4" with your actual input string, and adjust the field number as needed.
