# can you write a small script in a language of your choice that takes input as defined by the name of the input file, searches for patterns that resemble an ethernet mac address including those that omit the zero, such as like when netstat on macos does, then replace the last three octets of the mac address with xx:xx:xx | |
# it wrote python but python requires xcode so I asked for a rewrite in bash | |

Another way to characterize this is that the Ext4 file system variants tend to perform better on systems that have limited I/O capability. Ext3 and Ext4 perform better on limited bandwidth (< 200MB/s) and up to ~1,000 IOPS capability. For anything with higher capability, XFS tends to be faster. XFS also consumes about twice the CPU-per-metadata operation compared to Ext3 and Ext4, so if you have a CPU-bound workload with little concurrency, then the Ext3 or Ext4 variants will be faster. In general, Ext3 or Ext4 is better if an application uses a single read/write thread and small files, while XFS shines when an application uses multiple read/write threads and bigger files. | |

Git merge is like getting married. You find someone (or some branch) that you like and want to spend the rest of your life (or project) with. You propose (or create a pull request) and hope they say yes (or approve). Then you have a big ceremony (or a commit message) where you exchange vows (or diffs) and become one (or merge). You celebrate with your friends and family (or collaborators and followers) and hope for a happy future together. | |
But sometimes, things don't work out as planned. Maybe you rushed into the marriage (or merge) without knowing your partner (or branch) well enough. Maybe you had unrealistic expectations or incompatible goals. Maybe you discovered some flaws or bugs that you couldn't live with. Maybe you fell out of love (or sync) or found someone else (or a better branch). Whatever the reason, you decide to get a divorce (or revert the merge). | |
Getting a divorce (or reverting a merge) is not as easy as getting married (or merging). You have to go through a lot |
