+# Exercise 8, lab 8 #
+This exercise was about writing a nice little script that you find useful.
+Only requierment was that it should use sed and/or awk.
+So for this exercise I've written the following script(s).
+
+* [configure.sh](https://github.com/jackbenny/scripts_grundkurs/blob/master/Labb8/ovning5/configure.sh)
+	- A small script that configures failed\_logins.sh with new variables
+	for the hardcoded binary pathes. Useful in case this script is being run
+	a different distro which doesn't have the same pathes as Ubuntu.
