Get output from a while loop

Question

I have a file with dates where i want the dates to change to the day of the week using bash. I did this by the following while statement:

while read p; do
    date -d $p +%A
done <dates.txt

This works fine, but now i want the output of this statement in a file, say output.txt.

I tried

while read p; do
    date -d $p +%A
done <dates.txt >output.txt

But this gives the error date: extra operand '+%A'

I guess you want while IFS= read -r p; do date -d "$p" +%A; done > output.txt — KamilCuk

Welcome! Are you sure no change was made to dates.txt in-between the code change? Please note double quotes around $p in KamilCuk's suggestion, that's generally important. — Quasímodo

It worked, thanks for the help.

I now have

while IFS= read -r p; do
   date -d "$p" +%A
done <dates.txt >output.txt
