Remove all but newest two files (Not a duplicate post)
Code:
TARGET_DIR='/media/andy/MAXTOR_SDB1/Ubuntu_Mate_18.04/'
REGEX='[0-9]{4}-[0-9]{2}-[0-9]{2}_[0-9]{2}:[0-9]{2}'   # regular expression that match to: date '+%Y-%m-%d_%H:%M'
LATEST_FILE="$(ls "$TARGET_DIR" | egrep "^${REGEX}$" | tail -1)"

find "$TARGET_DIR" ! -name "$LATEST_FILE" -type f -regextype egrep -regex ".*/${REGEX}$" -exec rm -f {} +
# not working find "$TARGET_DIR" ! -name "$LATEST_FILE" -type f -regextype egrep -regex ".*/${REGEX}$" -print -f {} +

The REGEX and find statement is complicated and I do not understand much of what is going on behind the scenes.

I would like to modify it so it deletes these type of files from the next dir.

grepdiff

GREPDIFF(1)							     Man pages							       GREPDIFF(1)

NAME

       grepdiff - show files modified by a diff containing a regex

SYNOPSIS

       grepdiff [[-n] | [--line-number]] [--number-files] [[-p n] | [--strip-match=n]] [--strip=n] [--addprefix=PREFIX] [[-s] | [--status]]
		[[-i PATTERN] | [--include=PATTERN]] [[-x PATTERN] | [--exclude=PATTERN]] [[-v] | [--verbose]] [[-E] | [--extended-regexp]] [[-H]
		| [--with-filename]] [[-h] | [--no-filename]] [--output-matching=WHAT] {[REGEX] | [-f FILE]} [file...]

       grepdiff {[--help] | [--version] | [--list] | [--filter ...]}

DESCRIPTION

       For each file modified by a patch, if the patch hunk contains the REGEX then the file's name is printed.

       The regular expression is treated as POSIX Basic Regular Expression syntax, unless the -E option is given in which case POSIX Extended
       Regular Expression syntax is used.

       For example, to see the patches in my.patch which contain the regular expression "pf_gfp_mask", use:

	   grepdiff pf_gfp_mask my.patch | 
	     xargs -rn1 filterdiff my.patch -i

       You can use both unified and context format diffs with this program.

OPTIONS

       -n, --line-number
	   Display the line number that each patch begins at. If verbose output is requested, each matching hunk is listed as well.

	   For a description of the output format see lsdiff(1).

       --number-files
	   File numbers are listed, beginning at 1, before each filename.

       -p n, --strip-match=n
	   When matching, ignore the first n components of the pathname.

       --strip=n
	   Remove the first n components of the pathname before displaying it.

       --addprefix=PREFIX
	   Prefix the pathname with PREFIX before displaying it.

       -s
	   Show file additions, modifications and removals. A file addition is indicated by a "+", a removal by a "-", and a modification by a
	   "!".

       -i PATTERN, --include=PATTERN
	   Include only files matching PATTERN.

       -x PATTERN --exclude=PATTERN
	   Exclude files matching PATTERN.

       -E, --extended-regexp
	   Use POSIX Extended Regular Expression syntax.

       -H, --with-filename
	   Print the name of the patch file containing each match.

       -h, --no-filename
	   Suppress the name of the patch file containing each match.

       -f FILE, --file=FILE
	   Read regular expressions from FILE, one per line.

       --output-matching=hunk|file
	   Display the matching hunk-level or file-level diffs.

       --help
	   Display a short usage message.

       --version
	   Display the version number of grepdiff.

       --filter
	   Behave like filterdiff(1) instead.

       --list
	   Behave like lsdiff(1) instead.
