command line
Git Previous Branch
When working with Git on the command line, I spend a lot of time switching back and forth between two branches. Even with Git tab completion, it is a lot of typing. However Git has a shortcut for the previous branch, a single dash (-).
Curl Get Redirect
When creating 301 redirects, I often want to check multiple URLs quickly from the command line (to avoid the manual clicking in the browser and browser caching of results). I’ve written this script to speed up my process.
grep inside gzipped files
When faced with a folder full of gzipped files, I found I was unable to use my usual go to program grep to search for text in the files. However, zgrep came to my rescue.
DIG and WHOIS returning different name servers
You can look up the name servers associated with a domain name using either “whois” or “dig NS”. In some rare occasions, I have gotten back two different answers using these two techniques. In my experience, “dig NS” is the more trustworthy of the two.

Checksum on Mac OS X Command Line
The checksum is like a fingerprint for the file. A file is processed through a known algorithm which results in the checksum, a.k.a “hash”, which is a string of letters and numbers unique to that file, e.g. 8ab686eafeb1f44702738c8b0f24f2567c36da6d. If the file is modified, the resulting checksum will be different. This allows a quick way to […]
