Use GNU commands on macOS

README.md

coreutils

• Using GNU command line tools in macOS instead of FreeBSD tools

The default installed commands, such as date, may not be compatible with general Linux systems.

$ date -d '+10 minutes' +%s
date: illegal option -- d
usage: date [-jnRu] [-I[date|hours|minutes|seconds]] [-f input_fmt]
            [-r filename|seconds] [-v[+|-]val[y|m|w|d|H|M|S]]
            [[[[mm]dd]HH]MM[[cc]yy][.SS] | new_date] [+output_fmt]

To resolve this, install coreutils:

brew install coreutils

Next, add the following line to either ~/.zprofile or ~/.bash_profile:

export PATH="/opt/homebrew/opt/coreutils/libexec/gnubin:$PATH"

Afterward, the command should work as expected:

$ date -d '+10 minutes' +%s
1683467946

gnu-sed

brew install gnu-sed

export PATH="/opt/homebrew/opt/gnu-sed/libexec/gnubin:$PATH"

grep

brew install grep

export PATH="/opt/homebrew/opt/grep/libexec/gnubin:$PATH"

findutils

brew install findutils

export PATH="/opt/homebrew/opt/findutils/libexec/gnubin:$PATH"

gnu-time

brew install gnu-time

PATH="/opt/homebrew/opt/gnu-time/libexec/gnubin:$PATH"
alias time='/opt/homebrew/opt/gnu-time/libexec/gnubin/time'

or use TIMEFMT

export TIMEFMT=$'\n\n========================\nProgram : %J\nCPU     : %P\nuser    : %*Us\nsystem  : %*Ss\ntotal   : %*Es\n========================\n'

make

brew install make

PATH="/opt/homebrew/opt/make/libexec/gnubin:$PATH"

gzip

brew install gzip
