zcat won't unzip files properly

Question

I need to unzip a compressed file on the fly in my program. It works when I try it on my own linux computer, but for some reason the school computers fail whenever I tell them to do it. To unzip I'm using the following command:

 zcat /file/address/file.tar.gz

and get the error:

 /file/address/file.tar.gz.Z: No such file or directory

I tried looking through the documentation but couldn't find a flag to turn off this odd behavior.

Answer 1

Your school's system still has the old "compress" style utilities rather than the newer GNU "gzip" based ones.

You need to use gzcat rather than zcat , assuming that it's available.

Answer 2

当我想gzip时，我一般只是直接使用gzip：

gzip -dc /file/address/file.tar.gz

Answer 3

zcat archive.tgz | tar -x --wildcards apri/fls/filename

Answer 4

gzip --解压 /file/address/file.tar.gz

Answer 5

If you ad the .Z to the end of the filename like this :

zcat /file/address/file.tar.gz.Z

then it will find the file .
