yesterday
YESTERDAY(1) General Commands Manual YESTERDAY(1)
NAME
yesterday - print file names from the dump
SYNOPSIS
yesterday [ -c ] [ -date ] files ...
DESCRIPTION
Yesterday prints the names of the files from the most recent dump. Since dumps are done early in the morning, yesterday's files are really
in today's dump. For example, if today is March 17, 1992,
yesterday /adm/users
prints
/n/dump/1992/0317/adm/users
In fact, the implementation is to select the most recent dump in the current year, so the dump selected may not be from today.
With option -c, yesterday copies the dump file to the current directory.
The date option selects other day's dumps, with a format of 2, 4, 6, or 8 digits of the form dd, mmdd, yymmdd, or yyyymmdd.
Yesterday does not guarantee that the string it prints represents an existing file.
EXAMPLES
Back up to yesterday's MIPS binary of vc:
cd /mips/bin
yesterday -c vc
Temporarily back up to March 1's MIPS C library to see if a program runs correctly when loaded with it:
bind `{yesterday -0301 /mips/lib/libc.a} /mips/lib/libc.a
rm v.out
mk
v.out
