I would like to have a tidy resource that deletes all files recursively
from directories matching a pattern, except for the most recently modified
file.
Something like this:
tidy {
'clean up files except most recently modified one':
path => '/path/to/files',
recurse => true,
rmdirs => true,
age => '1h',
matches => 'some-pattern',
unless => '{bash script returning most recently modified file name}',
;
}
I understand that this is really stretching the scope of what tidy is for.
That is why I have decided to just use an exec with a long line of bash
that does what I want. However, this long and complicated line of bash code
is not ideal for me because it is hard to understand and maintain, it's
just kind of ugly:
# 1 - find all directories matching a pattern, print the most recently
modified time and path
# 2 - sort by most recently modified
# 3 - remove the timestamp
# 4 - remove the last item
# 5 - rm -rf all of the paths
find /path/to/files -maxdepth 1 -type d -name 'some*pattern' -printf '%T+
%p\n' | sort | cut -d' ' -f2 | head -n -1 | xargs rm -rf
Even if tidy is not an option, does anyone else have any better ideas than
my exec?
Thanks in advance
-Tony
