YESTERDAY(1) General Commands Manual YESTERDAY(1)NAMEyesterday - print file names from the dumpSYNOPSISyesterday [ -c ] [ -date ] files ...DESCRIPTIONYesterday 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.EXAMPLESBack 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.outFILES/n/dumpSOURCE/rc/bin/yesterdaySEE ALSOfs(4)BUGSIt's hard to use this command without singing.
