Top Forums UNIX for Beginners Questions & Answers Compress and logging files from October 6th in a loop Post 303024697 by rbatte1 on Monday 15th of October 2018 11:38:40 AM
Old 10-15-2018
Personally, I would avoid reading the output of ls -l because you could get false positives too easily. Maybe another approach might be better:-
Code:
touch -mt 201810060000 /tmp/start_point
touch -mt 201810070000 /tmp/end_point

echo "$(date) : Starting"

for file in $(find . -type f -newer /tmp/start_point ! -newer /tmp/end_point ! -name "*.gz")
do
   echo "$(date) : Compressing ${file}"
   echo gzip ${file}
done
echo "$(date) : Complete"

Remove the dark read echo if you are happy that it should work.

Does that help?

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. AUTHOR
