pyp
Easily run Python at the shell for data plumbing
TLDR
Double each line as an integer
$ seq 3 | pyp 'int(x)*2'
Sum numbers from stdin$ seq 10 | pyp 'sum(map(int, lines))'
Pretty-print JSON lines$ cat [data.jsonl] | pyp 'json.loads(x)'
Run with automatic imports explained$ pyp -b '...'
SYNOPSIS
pyp [*options*] *expression*
DESCRIPTION
pyp lets you use short Python expressions as shell filters. Each stdin line is available as x (and related helpers), and lines exposes all input for reductions. It automatically imports common modules when referenced, aiming to replace many awk/sed one-liners when Python is a better fit.Install via pip install pypyp (package name pypyp on PyPI; command is pyp).
PARAMETERS
*expression*
Python expression or small script applied to input.-b, --explain / magic import related flags
Explain automatic imports or control behavior (see pyp --help).-h, --help
Full option list for your installed version.
INSTALL
brew install pyp
nix profile install nixpkgs#pyp
CAVEATS
Python startup cost makes it slower than awk for huge streams. Automatic imports can surprise; prefer explicit imports for production scripts. Not a replacement for complex multi-file programs.
