(n) glob qualifierGlobs sort filenames character by character, so numbered files often come out in a surprising order, with 10 before 2. Zsh has a neat fix for this: the n glob qualifier, which applies a “natural” sort, treating any run of digits as a number rather than a string of characters.

:r (root) and :e (extension)Zsh modifiers are a family of suffixes that transform words as they’re expanded. Several of them are dedicated to slicing up filenames, replacing fiddly calls to dirname, basename, and friends. Let’s take a look at them now!
(e) or + glob qualifiersZsh glob qualifiers can select files by many built-in attributes: type, size, modification time, and more. But when no built-in qualifier fits, you can bring in the e or + qualifiers to run arbitrary code, making globs a fully programmable file filter. With great power comes great responsibility!

(om[1]) glob qualifiersI’ve recently been using memray, a memory profiler for Python, to optimize the startup memory usage (and time) for a client. It’s a fantastic tool, but its flexibility hampers getting instant feedback. It takes three commands to profile a program, generate a flame graph from the profile, and open the flame graph in the browser:
