Top Forums Shell Programming and Scripting script to view files based on date Post 85273 by vino on Tuesday 4th of October 2005 09:05:07 AM

In short RTFM.

From man touch

Code:
       -d, --date=STRING
              parse STRING and use it instead of current time

       -F, --forward=SECONDS
              Modify  the time by going forward SECONDS seconds.  For example,
              touch -r foo -F 5 bar will make the file  bar  5  seconds  newer
              than file foo.

       -r, --reference=FILE
              use this file's times instead of current time

That means create /tmp/OLD which has a timestamp provided by the user.

And then create /tmp/NEW which is exactly 24 hours newer compared to /tmp/OLD

And from man find,

Code:
       -newer file
              File was modified more recently than file.  -newer  is  affected
              by  -follow  only  if -follow comes before -newer on the command
              line.

       -size n[bckw]
              File uses n units of space.  The units are  512-byte  blocks  by
              default  or  if `b' follows n, bytes if `c' follows n, kilobytes
              if `k' follows n, or 2-byte words if `w' follows  n.   The  size
              does  not  count  indirect  blocks,  but it does count blocks in
              sparse files that are not actually allocated.

The find script says -- find all files which are newer than /tmp/OLD but not /tmp/NEW and whose size is not zero.

dh_compress

DH_COMPRESS(1)							     Debhelper							    DH_COMPRESS(1)

NAME
       dh_compress - compress files and fix symlinks in package build directories

SYNOPSIS
       dh_compress [debhelperoptions] [-Xitem] [-A] [file...]

DESCRIPTION
       dh_compress is a debhelper program that is responsible for compressing the files in package build directories, and makes sure that any
       symlinks that pointed to the files before they were compressed are updated to point to the new files.

       By default, dh_compress compresses files that Debian policy mandates should be compressed, namely all files in usr/share/info,
       usr/share/man, files in usr/share/doc that are larger than 4k in size, (except the copyright file, .html and other web files, image files,
       and files that appear to be already compressed based on their extensions), and all changelog files. Plus PCF fonts underneath
       usr/share/fonts/X11/

FILES
       debian/package.compress
	   These files are deprecated.

	   If this file exists, the default files are not compressed. Instead, the file is ran as a shell script, and all filenames that the shell
	   script outputs will be compressed. The shell script will be run from inside the package build directory. Note though that using -X is a
	   much better idea in general; you should only use a debian/package.compress file if you really need to.

OPTIONS
       -Xitem, --exclude=item
	   Exclude files that contain item anywhere in their filename from being compressed. For example, -X.tiff will exclude TIFF files from
	   compression.  You may use this option multiple times to build up a list of things to exclude.

       -A, --all
	   Compress all files specified by command line parameters in ALL packages acted on.

       file ...
	   Add these files to the list of files to compress.

CONFORMS TO
       Debian policy, version 3.0

SEE ALSO
       debhelper(7)

       This program is a part of debhelper.
