A bash function for prepending text to a file
Raw
prepend.md

Motivation

While bash lets you easily append to a file, there's no simple way to prepend to a file. The prepend function provides that functionality without relying on external tools like sed.

prepend() {
  printf '%s%s' "$1" "$(< $2)" > "$2"
}

Setup

Add the function to your .bashrc file.

Usage

$ prepend 'Text you want to prepend' path/to/file
