Re: [Bug-tar] Using tar with lz4

[Adam Erikssen]

Thanks for the hints

 

I was thinking about the second solution (add it) (and indeed, I was too wondering which letter could still be available for it, but ok, a long command --lz4 is a nice backup).

 

The first solution  

./configure --with-gzip=lz4

is an interesting intermediate step that I was not aware of,

although it seems to entirely remove gzip support from command line.

From my point of view, lz4 does not "replace" gzip. It's very useful for many transmission jobs I do, short-lived traces, log files, and so on, but the stronger compression ratio of gzip will sound preferable for some other usages.

Do you propose to use it instead of gzip?  You can do it using
the --with-gzip option while configuring GNU tar:

 ./configure --with-gzip=lz4 [...]

On the other hand, if you propose to add it as an additional
complressor, then of course it is possible.  Note, however, that we are
out of short command line options, so the only possibility is --lz4.

In the meantime, instead of

> tar -c [files] | gzip > archive.tar.gz

you can do this:

tat -c -f archive.tar.gz -Ilz4 [...]
