Alternative for Solaris compx/decompx utilities?

[d_girish_d]

We have compx/decompx utilities on solaris platform, which are from bTrade.
Now we are migrating from Solaris 5.8 to RHEL5, I am wondering do we have something similar over there? obviously we are not looking into buying the license for RHEL.

Thanks in advance,
Girish

A quick google search didnt help me much.

What are compx/decompx doing?

[d_girish_d]

These utilities are part of TDAccess software from bTrade.

So TDAccess is some kind of secure fileserver with access management capabilites, including certificates.
Is that right?

And from the sound of compx and decompx, they are used for compression.

But a little more information from your side would be helpful.
You are a user of TDAccess, most are not.

1) again: what do compx / decompx do?
2) are you looking for a DropIn replacement for TDAccess or just for compx/decompx?
3) what are you trying to achieve?

1) what do compx / decompx do?:
They are file compression utilities similar to compress/uncompress
2) are you looking for a DropIn replacement for TDAccess or just for compx/decompx?:
Just compx/decompx
3) what are you trying to achieve?
compx uses different compression alogorithm, which does not works with compress/tar utilities. so I am looking for some tool with which we can replace compx/decompx

gzip/gunzip and bzip2/bunzip2 are widely used on all unix like operating systems.
You might try and open your compx-files with them.

Perhaps this can give more information about the file format.

file <compx-file>

If it just returns "data", then the file format is unknown to file.

There is a possibilty, that compx/decompx uses own, proprietary compression algorithms.
If that is the case, you are out of luck.

This would then be called "vendor lock in".


As a last resort, you could decompress all your files with decompx and then recompress with a more standard tool, like the two mentioned above.

Solaris 5.8 wow that is old! If you aren't going to purchase a license for RHEL why would you install it? You should just use CentOS so you can get updates.
