If you are just looking for files containing a dot, you might run into problems with false positive.

Give an example of what the filenames are, is there anything that will identify the filenames?
If you are just looking for files containing a dot, you might run into problems with false positive.
An example would be: A-12345.123.jpg

These need to be changed from A-12345.123.jpg to A-12345_123.jpg

Thanks.

epinfo

EPINFO(1)							   User Commands							 EPINFO(1)

NAME

       epinfo - extract technical information from digital camera generated files

SYNOPSIS

       epinfo [-h] [-V] [-z] [-r] [-t] [-f fmt] [-T <TagName>] <filename> ...

DESCRIPTION

       This  command extracts the contents of TIFF directory of Exif files or APP12 marker from JFIF files, parses it and optionaly finds specific
       data inside it.	If used without -T, -r and -t options, dumps the complete block data in human readable format.	With -r  and  -t  options,
       renames and changes timestamp of the files.

OPTIONS

       -h   This option produces a help screen of all options and commands.

       -V   This option prints software revision information.

       -z   This  option  sets no time-zone processing mode.  Use this option if the camera's clock is set up shifted by the local timezone offset
	    (as it is when you set it manually to the local time).

       -r   Rename files, generating new name based on the time of snapshot and -f option value.

       -t   Set timestamp of the files to the time of snapshots.

       -f timeformat
	    This option allows to specify the format for automatically generated image file names; the value is used  as  the  format  string  for
	    strftime(3)  function.   By  default, names of the format "MMDD_NNN.jpg" are generated, where MM is a month, DD is a day, and NNN is a
	    count starting from 001.  A good starting point for the timeformat value could be "%Y_%m_%d-%H_%M_%S.jpg".	If the format string  con-
	    tains  context  "%%XXXd"  where  XXX  are digits, it is taken for the count, i.e. if the file with such name is present, next count is
	    tried.  If the format string does not contain "%%XXXd" part, the count field, if necessary, is appended at the end of the name.

	    A few single-character formats are used as shortcuts.  "x" makes the name of seconds since the epoch in hexadecimal format (8  charac-
	    ters  +  ".jpg"),  "d"  -  the  same in decimal format (10 characters), "1" stands for default format "%m%d_%%03d.jpg", "2" stands for
	    "%y%m%d%%02d.jpg", "3" stands for "%Y_%m_%d-%H_%M_%S.jpg" and 4 stands for "%Y/%m/%d/%H_%M_%S.jpg".  The program  attempts	to  create
	    intermediate directories is necessary (and possible).

       -T <TagName>
	    Output the value of this keyword in the information block.	Note that keywords are case sensitive.	TagName DateTime has special mean-
	    ing: if the file is Exif, it just prints the value of DateTime tag, and if the format is old APP12, it outputs the value  of  TimeDate
	    tag in the same format as Exif DateTime.

ARGUMENTS

       <filename> ...
	    List of filenames to process.

EXAMPLES

       % epinfo -f3 -rt pic00001.jpg

       % epinfo -T FNumber 0512_003.jpg
