 In rare cases you actually want word splitting, such as in
 
+```sh
 # shellcheck disable=SC2046
 gcc $(pkg-config --libs openssl) client.c
+```
 
 This is because `pkg-config` outputs `-lssl -lcrypto`, which you want to break up by spaces into `-lssl` and `-lcrypto`.
 
 A bash alternative in these cases is to use `read -a` for words or `mapfile` for lines. ksh can also use `read -a`, or a `while read` loop for lines. In this case, since `pkg-config` outputs words, you could use:
 
+```sh
 # Read words into an array in bash and ksh
 read -ra args < <(pkg-config --libs openssl)
 
 # expand args
 gcc "${args[@]}" client.c
+```
