HIST(1) 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 exam-
ple,
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
