Red Hat Based Distributions (Fedora/RHEL/CentOS/Amazon Linux)

Builds

We publish pre-built binaries as well as debs and rpms for the following OS:

• Darwin (Mac OS X)
• Linux
• FreeBSD

On these platforms:

• amd64 (64 bit x86)
• armv6 (32 bit ARM v6)
• armv7 (32 bit ARM v7)
• arm64 (64 bit ARM v8)

Currently we don't publish any 32-bit or Windows builds. If this causes hardship, let me know.

I don't think saw works in the Windows terminal emulator as is.

Usage

• Basic

  # Get list of log groups
  saw groups
  
  # Get list of streams for production log group
  saw streams production

• Watch

  # Watch production log group
  saw watch production
  
  # Watch production log group streams for api
  saw watch production --prefix api
  
  # Watch production log group streams for api and filter for "error"
  saw watch production --prefix api --filter error
