Question

How can I list all files newer than a given time? I’m looking for a one-liner that I can run in Bash with standard Linux utilities.

I know how to list all files newer than a given file (find . -newer FILE), but in my case I have a Unix timestamp (e.g. 1312604568) to compare them to, instead of a file.

This is a bit circuitous because touch doesn’t take a raw time_t value, but it should do the job pretty safely in a script. (The -r option to date is present in MacOS X; I’ve not double-checked GNU.) The ‘time’ variable could be avoided by writing the command substitution directly in the touch command line.

time=$(date -r 1312603983 '+%Y%m%d%H%M.%S')
marker=/tmp/marker.$$
trap "rm -f $marker; exit 1" 0 1 2 3 13 15
touch -t $time $marker
find . -type f -newer $marker
rm -f $marker
trap 0
