compress in diffrent directory

scofiled83 · 06-02-2009, 02:23 AM

Hi

I have a file size 7gb.
I cannot compress this file in current directory beacuse of insufficient space.

Can I perform the compression in some other mount point?

I use compress command.

Unix

Does compress -c file > /somepath/compressed_file

work?

scofiled83 · 06-02-2009, 03:02 AM

No it doesnt work

billymayday · 06-02-2009, 03:03 AM

Why not? It worked for me.

scofiled83 · 06-02-2009, 03:07 AM

could you please show in an example

Billimayday already showed you an example in post #2. If something goes wrong, please paste/copy the exact error message together with the issued command and give any additional information. In alternative to the compress command you can try gzip, using the same syntax:

Code:

gzip -c file_to_gzip > /path/to/file_gzipped.gz

the -c option sends output to standard output, leaving the original file unchanged. The redirection actually stores the output in a compressed file.

Hi
I have managed to compress file.
Its size is without compression 7gb
after compression 1gb.

I cannot uncompress the file by issuing:

uncompress full.dmp

file too large.

I used uncompress -c full.dmp

Since my file is binary, I see weird outputs in the screen during uncompression.

I am not sure wheter it is uncompressing or not, Is that normal or how can I uncompress it?

Of course you would have to use

uncompress -c full.dmp > full.dmp.uncompressed

although I suspect (but haven't tried it) it you compressed to full.dmp.Z (or renam it) you could just use

uncompress full.dmp.Z

scofiled83 · 06-02-2009, 04:16 AM

When I just use:

uncompress full.dmp.Z

I get file too large error message

billymayday · 06-02-2009, 04:24 AM

What about the first version?

Do you have enough space?

scofiled83 · 06-02-2009, 04:25 AM

I have space, but I cannot uncompress it

uncompress -c full.dmp.Z > full.dmp
full.dmp: File too large

billymayday · 06-02-2009, 04:29 AM

What type of filesystem is it?

Old applications supported files of only 2GB size - maybe it's your case.

7-zip ( http://www.7-zip.org/ ) supports unpacking of .Z files among others; it can be built under UNIXish systems, so maybe it'll solve your problem.

It compressed it though. I'm guessing it could be a FAT filesytem
