Miscellaneous Utilities
Dick Grune
These are some useful (to me, that is) UNIX and MSDOS utilities that I have written over the years. Most of them are what one could call `orientation aids' to fight chaotic overload. For example, `lmr' ("List Most Recent") will quickly tell me what on earth I was doing in this directory when I last worked on it perhaps half a year ago. Most programs do more than has been indicated here; many have man pages; some are trivial but have yet proved useful.
Most programs are served as .tar or .zip files. Most compile on other OSs. Some come with .exe files.
eh
EH
- as in "Eh?" -
gives a first impression of the contents of its arguments, which may be
text files, directories, etc.
A usual call is
'eh *'
to see what is going on in this directory.
Less wide than the UNIX command `file', but digs deeper.

name, without modifying the JPG itself.

2. correcting incorrect camera date/time settings.
