Brrrr, such an ugly solution. If you want proof against future then you should use longer naming, maybe something that ends in <First name initial, Last name initial, Middle name initial, Underscore, my>. Allows to get better implementations of existing ones and having a fixed schema can help you in the future as your personal tools library grows.
Examples:
cat -> cat_uni_my (personal implementation of standard cat)
grep -> grep_uni_my (personal implementation of standard grep)
maybe, but it's a lot easier to understand if you share your tools with other people. As for personal use, sure, you can do whatever you want, including using his comma style naming.
Examples:
cat -> cat_uni_my (personal implementation of standard cat)
grep -> grep_uni_my (personal implementation of standard grep)
