Take action only if a file is X hours (or seconds) old
shell: #!/bin/ash
I searched and found a few relevant posts (here and here - both by porter, on the same day (?)) however both are just a do while loop, I need to check a file date and compare it to the current time.
I would like it to say if file 'test' is more than 12 hours old than "right now" to echo back "file is stale" else echo "file is ok". I was thinking I could get the "unix time" of the file and just subtract them, but honestly I have no idea how to get the unix time of a file (much less in a script)
concept:
Code:
touch magic
$timediff = creation time of file magic - creation time of file test (in seconds)
if $timediff > 43200 (seconds) then echo "file is stale" else "file is ok"
I'm sure there is a better/easier way to do this... Thanks all!
# the last time a file was changed in epoch seconds
perl -e '@arr=stat $ARGV[0]; print "$arr[9]\n" ' filename
# now in epoch seconds
perl -e ' $now=time; print "$now\n" '
# therefore: now - filetime == age of file in seconds
perl -e '@arr=stat $ARGV[0]; $diff = time - $arr[9]; print "$diff\n" ' filename
There are less readable more compact ways to write the code, but this works for starters.
If you have GNU date on your system something similar is possible.
Have some files in /tmp/dir
abc.zip
123.zip
345.zip
