|
* Takes utmp formated file on stdin and dumps it's contents
|
|
* out in colon delimited fields. Easy to 'cut' for shell based
|
|
* versions of 'who', 'last', etc. IP Addr is output in hex,
|
|
* little endian on x86.
|
|
*
|
|
* Modified to support all sort of libcs by
|
|
* Erik Andersen <andersen@lineo.com>
