Thanks. I'm now beginning to understand the different features of sed vs awk.

From an article I have just read (as a new member I can't post the link yet) ..

Code:

Quote:
awk's key feature being to automatically split input lines into their component fields.
sed and awk both work through as python subprocess call (executing command line in python).

approx-import

APPROX-IMPORT(8)					      System Manager's Manual						  APPROX-IMPORT(8)

NAME

       approx-import - copy local .deb files into the approx cache

SYNOPSIS

       approx-import [OPTION]... file.deb ...

DESCRIPTION

       approx-import copies local .deb files, such as those found in /var/cache/apt/archives, into the approx(8) cache.

       It  does  so  by computing the MD5 checksum of each argument.  If it matches a package in one of the Packages files in the approx(8) cache,
       then the file is copied to the appropriate location in the cache.

       Note that all Packages files must be scanned, regardless of how many .deb files are being imported, and this process may take several  min-
       utes.

       The approx-import command must be run by the superuser or the approx(8) user.

OPTIONS

       -c file, --config file
	      Specify an additional configuration file.  May be used multiple times.

       -s, --simulate
	      Process files but do not actually copy them into the cache.

       -q, --quiet
	      Don't print the names of files that are imported.

       -v, --verbose
	      Print the disposition of each file.

EXAMPLES

       To import packages from the local apt(8) cache:

	      approx-import /var/cache/apt/archives/*.deb

       To import packages from another proxy's cache:

	      find other-cache -name "*.deb" | xargs approx-import

       (where other-cache is the pathname of the other proxy's cache directory)

FILES

       /etc/approx/approx.conf
	      Configuration file for approx and related programs.

       /var/cache/approx
	      Default cache directory for archive files.

SEE ALSO

       approx.conf(5), approx(8)
