|

Usage : lrztar [lrzip options] <directory>
|
||||
Result: a lrzip tarball is produced.
|
||||
Extras: when an lrzip tarball is used with -d, -O, it gets extracted:
|
||||
|
||||
-h: will display this message.
|
||||
-d: <path1> will decompress a <path1> lrzip tarball to current directory.
|
||||
-O: <path2> will decompress a -d specified lrzip tarball to <path2> path.
|
||||
-f: will force overwrites.
|
||||
|
||||
Final :
|
||||
- You can use the remaining options of lrzip as they were.
|
||||
- lrzuntar is equivalent to lrztar [options] -d <filename>.
|
||||
- This script exists because of how lrzip behaves.
|
||||
- Beware the -f flag, it stands for what it says...
