grep for date in file

scabral · #1 (**permalink**) 05-29-2007

Hi,

i have a script that stores the date in a variable as follows:

DATESTAMP=`date +"%m%d%Y"`

I also have another file called HOLIDAYFILE which stores all of our holidays as follows:

01/01/2007
07/04/2007

What i need to do is use the grep statement in my script to see if DATESTAMP is in the HOLIDAYFILE and store that in another variable, let's say HOLIDAY, and if HOLIDAY has a value then do nothing and exit the script, otherwise proceed with the code.

anyone have a good grep statement that would do this?

thanks
scott

DATESTAMP can be made to conform to the date format you have in HOLIDaYFILE

Code:

DATESTAMP=`date +"%m/%d/%Y"`

then you can grep for it.

If you can't modify the format of the date in DATESTAMP, create another variable with the right format :

Code:

DATESTAMP2=`date +"%m/%d/%Y"` # Sol 1
DATESTAMP2=$(echo $DATESTAMP | sed 's_^\(..\)\(..\)_\1/\2/_') # Sol 2

if grep -q $DATESTAMP2 HOLIDAYFILE
then
   echo "Holiday !!!"
fi
