Special commands in Porteus:lzm2xzm as an example
Posted: 03 Jul 2011, 04:18
This thread aim at giving more detailed explanations for some Porteus special and unique commands.
Here is one that I used lzm2xzm. It permits the transformation of modules compressed in the lzm format to be compressed in xzm, an even more efficient form of compression. In the following lines, some information will be given on its use, its syntax, but also some of its limitations.
Porteus has choosen xzm (for XZ compression modules) for verion 1,0 of its OS. XZ is synonym of LZMA2 compression:
Use:
lzm2xzm will allow the conversion of lzm modules into xzm modules.
Syntax:
lzm2xzm gimp.lzm
lzm2xzm gimp.lzm gimp.xzm
Limitations:
1. It works only for 32-bit to 32-bit modules or for 64-bit modules to 64-bit modules. You could not convert 32-bit to 64-bit and vis-et-versa, The libraries for these program being different and not compatible,see:

2. You can not use it for modules on NTFS or FAT partifion, see:

Other commands specific to Porteus, and that could be treated on this thread are:
txz2xzm
dir2xzm
Do you have some few to submit?
