How to GZIP all the files or a list of files from some path?
gzip will always compress each file into a single .gz file when given a list of files on its command line.
For example
$ gzip -r log.2011
to recursively walk the log.2011 directory and compress all files it finds, or
$ gzip log.2011/*
to compress only the files in the log.2011 directory without descending into subdirectories.
This will output a gz archive for each matching file, files are replaced by the archive:
gzip fileprefix*
Have a look to the '-r' flag too.
