Answer : Removing old files

To remove files older than 1 minute, do:

touch -t `perl -MPOSIX -e 'print strftime "%Y%m%d%H%M", localtime(time-60)'` /tmp/ref
find /some/dir ! -newer /tmp/ref -exec rm -f {} \;

For yesterday it depends if you mean 24 hours ago or based on midnight.  It's easy for 1 day or 7 days, you just do

find /some/dir -mtime +0 -exec rm -f {} \;
find /some/dir -mtime +6 -exec rm -f {} \;
