rename a section of a filename, i. e. example.1.{txt,conf,db} or 12345.1.{wav,ogg,mp3} and

change the 1 to a 2 in the filename while preserving the rest of it.

$ zmv -n '(.)(<->)(.[^.]#)' '$1$(($2+1))$3' # would rename x.0001.y to x.2.y. $ zmv -n '(.0#)(<->)(.[^.]#)' '$1$(($2+1))$3'

Rename files to lower case

$ zmv '*' '${(L)f}'

serially all files (foo.foo > 1.foo, fnord.foo > 2.foo, ..)

$ autoload zmv

System Design Cheatsheet

Picking the right architecture = Picking the right battles + Managing trade-offs

Basic Steps

1. Clarify and agree on the scope of the system

• User cases (description of sequences of events that, taken together, lead to a system doing something useful)
  • Who is going to use it?
  • How are they going to use it?

Your problem with Vim is that you don't grok vi.

Answer by Jim Dennis on Stack Overflow question: what is your most productive shortcut?

You mention cutting with yy and complain that you almost never want to cut whole lines. In fact programmers, editing source code, very often want to work on whole lines, ranges of lines and blocks of code. However, yy is only one of many way to yank text into the anonymous copy buffer (or "register" as it's called in vi).
