Re: gunzip tgz problems

see if this works
#gunzip xxx.tgz|xargs tar xvf

Any way u can do it in 2 commands ;)

Re: gunzip tgz problems

i wanted to place the output of the tar in
/usr/local/include ...

i was able to unzip the file which created a icu4c-3_6-src.tar file, and then i did a 'tar xvf icu4c-3_6-src.tar' and copied the resulting directory into /usr/local/include..

Re: gunzip tgz problems

you really cannot redirect the contents of an untar.

Tar achives are either absolute or relative and will restore including their archived paths.

If it is relative the tar will extract into the current directory. cd to change the directory.

And as mentioned, -f is the name of the tar file and in this case will attempt to extract from /usr/local/include which is a directory and not a tar file.


man tar

Hi,

a possible better solution:
cd /usr/local/include
/usr/contrib/bin/gunzip < /FULLPATH/icu4c-3_6-src.tgz | tar xf -

Because it's nonsense?.

What, exactly, are you trying to do?

Or, depending on what you really want to do,
possibly:

( cd /usr/local/include ; \
gzip -dc valid/path/to/icu4c-3_6-src.tgz | \
tar xf - )

But plopping junk directly into
/usr/local/include sounds like a bad idea, in
general.

What's in the tarfile? Are the paths relative or absolute?
If you need to change the paths, you can use pax's: -s:old:new:

>Tim: you really cannot redirect the contents of an untar.

Sure you can. It's called pax(1). :-)

Peter: gunzip < /FULLPATH/icu4c-3_6-src.tgz | tar xf -

Right. I typically use gzcat:
gzcat /FULLPATH/icu4c-3_6-src.tgz | tar -xf -

Or GNU "tar", but sometimes it get tiring to
recommend the same old solutions every time,
especially when the original problem
statement lacks enough detail to let anyone
discern what really needs to be done.

Re: gunzip tgz problems

becuase of my ignorance of unix i did ask a stupid question, i thought i could untar into a directory not realizing that the directory was already specified in the tar file..
