Tool in UNIX to subtract dates
Is there any tool in Solaris UNIX (so no GNU tool available) to subtract dates? I know that in Linux we have gawk that can subtract one date from another. But in Solaris the maximum we have is nawk (improved awk) which cannot perform date calculations. Also I cannot use perl.

How to recover data from a bad SD card?
I have a 4GB SD card with some family pictures on it that I need to recover. When I insert the card into my card reader, it shows up as an unknown 32MB device (as /dev/sde) and cannot be mounted. When inserting back into the camera (a Nikon D60), it says the cards needs to be formatted (as does inserting it into a Windows machine). I want to recover all of the pictures on the card (there were others before the family pictures) because I don’t know how many I took or their exact sizes (but I believe they were all JPEGs). The card should be formatted as a FAT32 filesystem.

Why does this happen? Everything else printable with uname is shown.
I am not looking into fixing this. Even the manual page of uname says that it’s a common output.
sponge from moreutils – what’s the difference to shell redirect? useful examples?
sponge reads standard input and writes it out to the specified file.
Unlike a shell redirect, sponge soaks up all its input before writing
the output file. This allows constructing pipelines that read from
and write to the same file.
