I'm pretty sure that zgrep only work on .gz files, not .par (i.e. zip) files. :)

      Incorrect. The only chance for zgrep to succeed is that your data is too small, so zip used "store" instead of the "deflate" algorithm. To wit:
      % perl -e 'print "DB_File" x 1000' > test.txt
      % zip test.zip test.txt
      % zgrep DB_File test.zip |wc
             0       0       0
      
        [user@dirty-bastard ddate]$ zipinfo ddate.zip
        Archive: ddate.zip 20000 bytes 7 files -rw---- 2.0 fat 5145 tx defX 13-Feb-99 05:00 DDATE.MAN -rw---- 2.0 fat 4917 tx defX 13-Feb-99 05:00 DDATE.TXT -rw---- 2.0 fat 10529 tx defX 13-Feb-99 05:00 DDATE2D3.C -rwx--- 2.0 fat 9658 bx defX 13-Feb-99 05:00 DDATE2D3.EXE -rw---- 2.0 fat 10427 tx defX 13-Feb-99 05:00 DDATE3D3.C -rw---- 2.0 fat 431 tx defX 13-Feb-99 05:00 MANIFEST -rw---- 2.0 fat 772 tx defX 13-Feb-99 05:00 WHATS.NEW 7 files, 41879 bytes uncompressed, 19116 bytes compressed: 54.4%

        [user@dirty-bastard ddate]$ zgrep ddate ddate.zip

        ddate - converts Gregorian dates to Discordian dates therefore getting ready to complain that ddate returns C:\> ddate C:\> ddate +"Today is %{%A, the %e of %B%}, %Y. %N%nCelebrate % +H" C:\> ddate +"It's %{%A, the %e of %B%}, %Y. %N%nCelebrate %H" 9 + 26 1995 C:\> ddate +"Today's %{%A, the %e of %B%}, %Y. %N%nCelebrate %H +" 2 29 1996 ddate returns non-NULL values for September 3 rd - today etc. ddate won't stop stop you from telling it there
