Last date of the previous month

I want to get the Last date of the previous month and the code I'm using is date -d "$(2022-04-30 %Y%m01) -1 month" %Y-%m-%d. The output I'm getting is 2022-04-24 instead of 2022-03-31. I'm using Debian Linux.

Try out this one:

last_date=$(date -d "`date  %Y%m01` -1 day"  %Y-%m-%d)

CodePudding user response：

# last day of last month
date -d "$(date  %d) days ago"  %Y-%m-%d
# or
date -d "-$(date  %d) days"  %Y-%m-%d

# last day of this month
date -d "$(date  %d) days ago month"  %Y-%m-%d
# or
date -d "-$(date  %d) days month"  %Y-%m-%d
