I want to specify a range of time and count the weekdays within this range in bash. I found this snipped and edited it to print January and February in 2020:
#!/bin/bash startdate=2020-01-01 enddate=2020-02-28 curr="$startdate" while true; do echo "$curr" [ "$curr" \< "$enddate" ] || break curr=$( date +%Y-%m-%d --date "$curr +1 day" ) done
Now I only want to print all Mondays within this range, how can I do this?
I though of replacing
echo "$curr" by something like:
echo "$curr" | date +%Y-%m-%d-%a or without echo like:
date +%Y-%m-%d-%a <<< "$curr" to add the weekdays to the output with
%a and then filter the Mondays with
awk and count them. Though my approach of formatting the output this way does not work.
