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

Try this to get the current Monday's date.

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

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

You can then do this:

# Most recent Monday
date -v -Mon

# Output as of this writing
Mon Jun 24 12:35:48 EDT 2013

date -v -Mon "+%Y%m%d"

# Outputs
20130624

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

# Today's date
date

# Outputs
Thu Jun 27 12:41:39 EDT 2013

# Most recent Thursday
date -v -Thu

# Outputs
Thu Jun 27 12:41:46 EDT 2013

#monday
date -dmonday +%Y%m%d

#last monday
date -dlast-monday +%Y%m%d

#next monday
date -dnext-monday +%Y%m%d

#two mondays from now
date -d'monday+14 days' +%Y%m%d

#two mondays ago
date -d'monday-14 days' +%Y%m%d

#although, if you fancy yourself an Abraham Lincolin
date -d'monday-fortnight ago' +%Y%m%d #2 weeks ago
date -d'monday+fortnight' +%Y%m%d #2 weeks from now

#Monday Next Year
date -d'52+monday' +%Y%m%d

#However, Monday Last Year
date -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 Tuesday
echo `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

I think this actually answers what was requested:

date -d "next monday - 7 days"
