I want to use the command find to delete files over a certain date from a FTP directory on the router (these are CCTV recordings so take up a fair bit of room on my external drive). My plan was to use the find command in a cron script thus: find ‘/mnt/data/ftp_root/cctv/’ -type f -mtime +3 -delete
The version of find in Busybox on the router appears to not have the -mtime option included? (I haven’t tried the -delete option yet as I didn’t want to delete everything in that dir!)
BusyBox v1.25.1 (2017-09-13 19:43:58 CEST) multi-call binary.
Usage: find [-HL] [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’
-L,-follow Follow symlinks -H ...on command line only -xdev Don't descend directories on other filesystems -maxdepth N Descend at most N levels. -maxdepth 0 applies actions to command line arguments only -mindepth N Don't act on first N levels -depth Act on directory *after* traversing it
Actions:
( ACTIONS ) Group actions for -o / -a
! 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
-path PATTERN Match path to PATTERN
-ipath PATTERN Case insensitive -path
-regex PATTERN Match path to regex PATTERN
-type X File type is X (one of: f,d,l,b,c,…)
-perm MASK At least one mask bit (+MASK), all bits (-MASK),
or exactly MASK bits are set in file’s mode
-user NAME/ID File is owned by given user
-group NAME/ID File is owned by given group
-size N[bck] File size is N (c:bytes,k:kbytes,b:512 bytes(def.))
+/-N: file size is bigger/smaller than N
-prune If current file is directory, don’t descend into it
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
Though the busybox command help shows it should be there!

Am I doing something wrong or is this a software issue not spotted yet?
