These include: lockfile-create lockfile-remove lockfile-touchlock mail-lock mail-unlock mail-touchlock These programs use liblockfile to perform the file locking and unlocking, so they are guaranteed compatible with Debian's file locking policies.

Break lines after, for example 78 characters, but don't break within a word/string
Per default, linux/unix shells are configured with a width of 80 characters. If you like to edit a phrase or string on a line with more than 80 characters it might take long to go there (for example a line with 1000 characters and you like to edit the 98th word which is character 598-603). Maybe you might wish to use 78 characters, because if you forward the text via mail and the text will be quoted (2 extra characters at the beginning to the line "> "), you use 80 characters, otherwise 82, which are lame.

jhead is a very nice tool to do all sorts of things with photographs, in a batch-oriented way. It has a specific function to rename files based on dates, and the format I used above was just an example.
