Finding All Dates Between Two Dates in Bash

Question

I am trying to get all the dates that fall between a start and end date. This is what I did

start="2022-03-02" end="2022-03-07" while [[ $start < $end ]] do echo "$start" start=$(date -d "$start + 1 day" +"%Y-%m-%d") done

This results in an error

usage: date [-jnRu] [-d dst] [-r seconds] [-t west] [-v[+|-]val[ymwdHMS]] ... [-f fmt date | [[[mm]dd]HH]MM[[cc]yy][.ss]] [+format]

What is it I am missing?

I've tried it and it works in my environment. Output: 2022-03-02 2022-03-03 2022-03-04 2022-03-05 2022-03-06 — David Lukas

the code works for me; the issue is likely with your version of date; what does date --version report? — markp-fuso

offtopic: I would rename start to something like loopdate. Most people will expect a start value to be fixed. — Walter A

You can try this if you using on MacOs

date -j -v+1d -f %Y-%m-%d $start +%Y-%m-%d
