What is a .PS1 file?
PS1 is a Microsoft PowerShell script - a plain-text file of PowerShell commands used to automate administration on Windows, macOS and Linux.
- Did you know
- PowerShell launched in 2006 and went cross-platform and open-source as PowerShell Core in 2016.
- PowerShell pipes rich .NET objects between commands rather than plain text, which sets it apart from traditional Unix shells.
- By default Windows blocks running .ps1 scripts, an execution policy meant to stop malicious scripts running by accident.
- What Analyser shows you
- Preview and inspect HTML, CSS, JavaScript, TypeScript, JSON, YAML, XML and Markdown source files, plus Windows scripts. TypeScript (TS, MTS, and .d.ts declaration files) gets a structure readout beside the source: the modules it imports (packages against local files, and which are type-only), the names it exports, what it declares - interfaces, type aliases, enums, classes, functions - a code/comment/blank line breakdown, and how often it steps around the type system with any, as casts, non-null assertions and @ts- suppressions. PowerShell (PS1, PSM1, PSD1) is read for its comment-based help synopsis, #Requires directives, function and parameter counts, CmdletBinding and Authenticode signing; batch/command scripts (BAT, CMD) for the echo state, labels, variables set and the external tools they invoke.
