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?

ZMORE(1)						    BSD General Commands Manual 						  ZMORE(1)

NAME
zmore, zless -- view compressed files SYNOPSIS
zmore [flags] [file ...] zless [flags] [file ...] DESCRIPTION
zmore is a filter that allows the viewing of files compressed with Lempel-Ziv encoding. Such files generally have a ``Z'' or ``gz'' exten- sion (both the compress(1) and gzip(1) formats are supported). Any flags that are specified are passed to the user's preferred PAGER (which is /usr/bin/more by default). zless is equivalent to zmore but uses less(1) as a pager instead of more(1). When multiple files are specified, zmore will pause at the end of each file and present the following prompt to the user: prev_file (END) - Next: next_file Where prev_file is the file that was just displayed and next_file is the next file to be displayed. The following keys are recognized at the prompt: e or q quit zmore. s skip the next file (or exit if the next file is the last). If no files are specified, zmore will read from the standard input. In this mode zmore will assume gzip(1) style compression since there is no suffix on which to make a decision. ENVIRONMENT
PAGER Program used to display files. If unset, /usr/bin/more is used (zmore) or /usr/bin/less (zless). SEE ALSO
compress(1), less(1), more(1) BSD
