Print date for the monday of the current week (in bash)

#mondaydate -dmonday +%Y%m%d#last mondaydate -dlast-monday +%Y%m%d#next mondaydate -dnext-monday +%Y%m%d#two mondays from nowdate -d'monday+14 days' +%Y%m%d#two mondays agodate -d'monday-14 days' +%Y%m%d#although, if you fancy yourself an Abraham Lincolindate -d'monday-fortnight ago' +%Y%m%d #2 weeks agodate -d'monday+fortnight' +%Y%m%d #2 weeks from now#Monday Next Yeardate -d'52+monday' +%Y%m%d#However, Monday Last Yeardate -d'52-monday' +%Y%m%d  #DOES NOT  WORK#you can try a day other than monday#and format this differently.

if a range is what your after you may need to do a few things

#Tuesday to Sunday#since today is monday, I'll use Tuesdayecho `date -dtuesday +%Y%m%d-``date -dnext-sunday +%Y%m%d`

which would output:

20110628-20110703

More on Dates

note this only works on GNU date

I have read that:

Solaris version of date, which unable to support -d can be resolve with replacing sunfreeware.com version of date

For those of us without GNU dates (like us OS Xers), we may have the "-v" parameter

You can then do this:

# Most recent Mondaydate -v -Mon# Output as of this writingMon Jun 24 12:35:48 EDT 2013date -v -Mon "+%Y%m%d"# Outputs20130624

This also seems to not be a problem if today is Monday, in my current case Thursday

# Today's datedate# OutputsThu Jun 27 12:41:39 EDT 2013# Most recent Thursdaydate -v -Thu# OutputsThu Jun 27 12:41:46 EDT 2013

Try this to get the current Monday's date.

wd=`date +%u`; let wd=wd-1; mon=`date --date="-$wd day" +%Y%m%d`;
