usergen - user name generator

Small program to generate usernames, such as AmbitiousParrot2012, LonelyPossibility87965 and HopefulBird7776.

usergen offers a cheap, simple and fast way to create large numbers of user names, for example for testing or staging environments. No need to burn through your GPT tokens to generate user names 😊.

Without any command line arguments, usergen generates a single user name and prints it to stdout:

$>./usergen
GreenWeekend7438
$>

Pattern

You can provide a pattern to control how the user names are patched together. By default, the standard pattern is AdjectiveNounNumber4 (see also above). By providing a pattern as command line argument, usergen generates different user names. For example, the pattern the_Adjective_And___Noun generates user names of the following forms:

$>./usergen the_Adjective_And___Noun -c 5
the_Punctual_And___Bug
the_Comical_And___Dinner
the_Defiant_And___Yard
the_Mawkish_And___Kitchen
the_Quirky_And___Button
$>

The -c 5 parameter tells the program to generate five user names. The following elements are recognized to build patterns:

• Adjective: upper case adjective
• adjective: lower case adjective
• Noun: upper case noun
• noun: lower case noun
• Number: random number, followed by a single digit to denote the number of digits of the random number

Options

The following additional options can be used to control the output of usergen.

• -c, --count: number of user names to generate
• -s, --seed: srand initializer seed number. If not provided, a time-based initialization will be used.

How to compile

Since usergen is a single source file, compiling is trivial:

clang usergen.c -o usergen

I use clang in this case, but any other C compiler should do as well.

License

Do whatever you want with it. I stole parts of it and you can steal mine too.
