 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 words from one line into an array in bash and ksh, then expand each as args
 read -ra args < <(pkg-config --libs openssl)
+gcc "${args[@]}" client.c # expand as args
 
-# expand args
-gcc "${args[@]}" client.c
+# Read lines into an array, then expand each as args
+readarray -t file_args < <(find /etc/ -type f | grep some-check)
+your-linter.sh "${file_args[@]}" # expand as args
