dynamic date value in shell scripts

dynamic date value in shell scripts
using a variable – easier to read in scripts:
NOW=$(date +”%Y%m%d%H%M%S”)
echo “bar” > “$NOW”foobar.txt

one-line, equivalent to above:
echo “bar” > $(date +”%Y%m%d%H%M%S”)foobar.txt

alternate single-line format:
echo “bar” >> $(date “+myfile%Y%m%d.txt”)

man strftime to see formatting values
