Help With Custom Script

[ecnav]

I'm trying to make a script that finds DIRECTORIES that are older than X days and delete them. So far, I am successful doing so if I'm trying to delete FILES. But I need it to include directories.

This is what I have:
#!/bin/sh
find /tmp/mnt/sdb1/Left/Archive/ -mtime +15 -exec rm -rf {} \;
find /tmp/mnt/sdb1/Right/Archive/ -mtime +15 -exec rm -rf {} \;

I don't believe this will include the directories inside the Archive directory. Adding -type d does not work; -type is not a valid switch here. It seems to be valid in DDWRT but not in Merlin.

Here's a quick test:
RT-N66U:/jffs/scripts# find /tmp/mnt/sdb1/Left/ -type d -mtime +15 -exec ls -lh {} \;
find: unrecognized: -type
BusyBox v1.20.2 (2015-01-09 00:44:43 EST) multi-call binary.

Usage: find [PATH]... [OPTIONS] [ACTIONS]

Search for files and perform actions on them.
First failed action stops processing of current file.
Defaults: PATH is current directory, action is '-print'

-follow Follow symlinks

Actions:
! ACT Invert ACT's success/failure
ACT1 [-a] ACT2 If ACT1 fails, stop, else do ACT2
ACT1 -o ACT2 If ACT1 succeeds, stop, else do ACT2
Note: -a has higher priority than -o
-name PATTERN Match file name (w/o directory name) to PATTERN
-iname PATTERN Case insensitive -name
-mtime DAYS mtime is greater than (+N), less than (-N),
or exactly N days in the past
If none of the following actions is specified, -print is assumed
-print Print file name
-print0 Print file name, NUL terminated
-exec CMD ARG ; Run CMD with all instances of {} replaced by
file name. Fails if CMD exits with nonzero

There is a directory in there:

RT-N66U:/tmp/mnt/sdb1/Left# ls -lh |grep -i archive
drwxrwxrwx 2 Admin root 704.0K Feb 24 01:00 Archive

Any other suggestions as how I can accomplish this? I don't mind if it blows out all the files AND directories. I just need the directories gone.

How about "find tmp/mnt/sdb1/Left/Archive/ -ctime +15 -delete"?

 

[ColinTaylor]

You just have to be patient.

Because you have just deleted files within a directory the modification time of that directory is updated, so it no longer matches the "-mtime +15". Assuming that you don't modify that directory again, after another 15 days the test will match that directory and it will be deleted.

Thanks for your responses all.

What will +ctime do that +mtime is not? I also do not see -ctime listed as a valid option.

ColinTaylor - That makes perfect sense now. I'll try to wait it out to see if the directories ultimately go away. I don't mind if it is behind; as long as it cleans itself up without me having to log in.

As you have noticed +ctime is not an available option on the ASUS. If it were, here is a good explanation of how ctime and mtime effects directories: http://serverfault.com/questions/38...ways-change-when-a-new-file-is-created-inside

Perhaps install "findutils" via Entware?
(I forgot I had installed it.)

Here are some it's extended features, as seen on my RT-N66U.

admin@merlin:/tmp/home/root# find --help
Usage: find [-H] [-L] [-P] [-Olevel] [-D help|tree|search|stat|rates|opt|exec] [path...] [expression]

default path is the current directory; default expression is -print
expression may consist of: operators, options, tests, and actions:

operators (decreasing precedence; -and is implicit where no others are given):
      ( EXPR )   ! EXPR   -not EXPR   EXPR1 -a EXPR2   EXPR1 -and EXPR2
      EXPR1 -o EXPR2   EXPR1 -or EXPR2   EXPR1 , EXPR2

positional options (always true): -daystart -follow -regextype

normal options (always true, specified before other expressions):
      -depth --help -maxdepth LEVELS -mindepth LEVELS -mount -noleaf
      --version -xdev -ignore_readdir_race -noignore_readdir_race

tests (N can be +N or -N or N): -amin N -anewer FILE -atime N -cmin N
      -cnewer FILE -ctime N -empty -false -fstype TYPE -gid N -group NAME
      -ilname PATTERN -iname PATTERN -inum N -iwholename PATTERN -iregex PATTERN
      -links N -lname PATTERN -mmin N -mtime N -name PATTERN -newer FILE
      -nouser -nogroup -path PATTERN -perm [-/]MODE -regex PATTERN
      -readable -writable -executable
      -wholename PATTERN -size N[bcwkMG] -true -type [bcdpflsD] -uid N
      -used N -user NAME -xtype [bcdpfls]
      -context CONTEXT


actions: -delete -print0 -printf FORMAT -fprintf FILE FORMAT -print
      -fprint0 FILE -fprint FILE -ls -fls FILE -prune -quit
      -exec COMMAND ; -exec COMMAND {} + -ok COMMAND ;
      -execdir COMMAND ; -execdir COMMAND {} + -okdir COMMAND ;
