Counting files in the current directory using linux

To determine how many files there are in the current directory, put in ls -1 | wc -l.

ls -1 (ie: a one):
prints in one column and avoids the display of the total line (which would otherwise increase the line count).
"total" indicates the number of file system blocks used by files in the directory.

wc -l (ie: an L):
counts the lines (as switched by the L, not interested in characters or words)

Fixing a https Cert in Windows

I renewed a https cert today in Windows and had problems with the new Cert sticking in Windows It would add fine, without error, but would disappear when the IIS Server Certificates screen would refresh. Open the Certificates in MMC (Local Machine) and inspecting the Web Hosting gave a clue, the new certificate was there, but with a key - the private key was missing. Could be because the original certificate was created on a completely different machine and imported to this new server. At any rate, a simple certutil command fixed it .

Ever need to reset a password in Bonobo Git Server ?

So, you've forgotten your password to bonobo git. Step 1: Get access to the sqlite file, probably called something like Bonobo.Git.Server.db, sitting in the "wwwroot\Bonobo.Git.Server\App_Data" directory. Step 2: Using another tool, generate an md5 hash of your new desired password (as far as I know, sqlite does not have md5 capability) Step 3: Back in sqlite, using SQL, update the relevant user record, something like update User set Password = UPPER( 'thenewMD5hash') where Username = 'admin' ; Step 4: That's it, you are done, log in with your newly found password.

The web.config no extension mime problem Lets Encrypt on IIS/Windows

Tip when using LetsEncrypt in Windows - Feature Requests - Let's Encrypt Community Support In a paragraph, just use the web.config file to set the mime type, eg... After trying to figure out why my Lets Encrypt failed to generate in Windows, and discovering that it's the no extension mime type problem, I wondered whether certbot could fill in the missing gap. All that is needed is the following web.config file to be placed in the same directory as the challenge <?xml version="1.0" encoding="UTF-8"?> <configuration> <system.webServer> <staticContent> <mimeMap fileExtension="." mimeType="text/xml" /> </staticContent> </system.webServer> </configuration> Because there's no mime type for files without an extension on IIS, IIS sends back a 404 when verification happens. The web.config file above sets the mime type. After I created the .well-known
