dt00=$(date +%Y%m%d%H%M%S) echo "// __ \$dt00: |${dt00}|" ... after some long processing for which seconds would be exact enough, then I would like to get the seconds elapsed since dt00, like this:
dt02=$(date +%Y%m%d%H%M%S) echo "// __ \$dt02: |${dt02}|" you get seconds in dt00 and dt02 and then the difference. You can't go: $(( dt02 - dt00 )) because bash Arithmetic is 10-based. I am pretty sure there is such a thing in bash, but I can't find it in my scripts. lbrtchx
