SYNOPSIS
needs [options] [executables...]
DESCRIPTION
needs is a CLI tool that verifies whether specified executables are installed on a system and can retrieve their version information. It runs checks with multi-threaded execution, provides colored output, supports pipe-friendly output, and logs timing per command.
Exit codes indicate whether all required tools are present, making it suitable for use in scripts and CI pipelines.
PARAMETERS
--no-version
Skip version checks for faster execution.-f, --file FILE
Read requirements from a needsfile.-v, --verbose
Show detailed timing and log information.
CAVEATS
Version detection relies on each tool supporting a standard version flag (--version or -v). Some tools may not be detected correctly.
HISTORY
needs was created by NQMVD and is written in Rust.
