Shell Programming and Scripting

Hi

source is text file named alpha.text containing entries

ABC
DEF
XYZ
YYY
BBB


I need a small shell script which should do read the entries in alpha.text one by one and check it with the current date. If the date is Mon (monday) and entry read from the file is 'DEF' then this should be ignored and the script should read the next line XYZ....YYY etc. The output i need is

echo "ABC is present on Sun"
echo "XYZ is present on Mon"

Thanks

Requirement is not very clear; what do you want to happen on Saturday, Sunday, Monday, Tuesday, Wednesday, etc?

other days are normal for all strings. Only on Monday and only for that one string 'DEF' on Monday the script should ignore

day=`date +%w`
while read line
do
if [ "$day" == 1 -a "$line" == "DEF" ]; then
skip=0
else
echo $line
fi
done < ref_date

contents of the ref_date file is as below:

ABC
DEF
XYZ
YYY
BBB

requirement still not very clear. provide output/input sample when run on a SAT.

set `date`;
while read line;
do if [[ "$line" == "DEF" && "$1" == "Mon" ]];then
null;
else echo "$line is present on $1";
fi;
done < filename

This will give o.p as
ABC is present on Sat
DEF is present on Sat
XYZ is present on Sat
YYY is present on Sat
BBB is present on Sat
