Top Forums Shell Programming and Scripting Compressing & removing files in a directory & subdirectory Post 302983228 by Peasant on Saturday 8th of October 2016 03:31:13 AM

Use \+ if you are passing files to utilities which can handle multiple files.

This is valid in both gzip and cp, and you should gain performance with small change.

Also, files with .gz extension gzip will not attempt to compress, but rather print on stderr that file(s) already have gz extension and it will skip it.
Keep in mind that if fileXYZ.gz exists on same location where same fileXYZ is being compressed, gzip will prompt you for overwrite halting your program awaiting user input.

You really don't want to come to a machine after N days/months to see N crons with N finds awaiting user input..

Hope that helps

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

NAME
zmore -- view compressed files SYNOPSIS
zmore [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). 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. SEE ALSO
compress(1), less(1), more(1) BSD
