HIST(1)

NAME
hist, history - print file names from the dump

SYNOPSIS
hist [ -vdu ] [ -s yyyymmdd ] files ...

DESCRIPTION
Hist prints the names, dates, and sizes of all versions of the named files, looking backwards in time, stored in the dump file system. If the file exists in the main tree, the first line of output will be its current state. For example,

        hist ~rsc/.bash_history

produces

        May 19 16:11:37 EDT 2005 /home/am3/rsc/.bash_history 6175
        May 18 23:32:16 EDT 2005 /dump/am/2005/0519/home/am3/rsc/.bash_history 5156
        May 17 23:32:31 EDT 2005 /dump/am/2005/0518/home/am3/rsc/.bash_history 5075
        May 16 07:53:47 EDT 2005 /dump/am/2005/0517/home/am3/rsc/.bash_history 5065

The -v option enables verbose debugging printout.

The -d option causes diff(1) -c to be run for each adjacent pair of dump files, while -b runs diff -cb.

The -u option causes times to be printed in GMT (UT) rather than local time.

Finally, the -s option sets the starting (most recent) date for the output.

EXAMPLES

Examine changes in block.c:

        hist -d block.c

BUGS
Should be called history, but that name is taken by sh(1).
