Go

Environment Setup

Go is configured system-wide in /etc/profile:

export PATH=$PATH:/usr/local/go/bin

Optional (if you want Go-installed binaries accessible globally):

export GOPATH=/root/go
export PATH=$PATH:$GOPATH/bin

Apply immediately:

source /etc/profile

Workspace Layout

• /root/go/bin → binaries installed via go install (not in PATH unless you add it)
• /root/go/pkg → compiled package cache
• /root/go/src → source code

Useful Commands

• go version → check version
• go env → inspect environment
• go run → run a program
• go build → compile
• go install → install
