Untar file into a specific folder?

[youradds]

Hi. I have search hi-and-low for this. Google, Yahoo, Ask.com, looked at the official website for Tar, but still no luck.

Is it possible to extract *one* file from a .tar file, into a given directory, in the command. Something like;

`tar -xof /full/path/to/file.tar file.txt > /path/to/extraxct/to`

I'm ultimatly trying to do this with PHP, so its vital I can do it in one command

Cheers

Andy

tar xvf tarfile.tar filetoextract -C /path/to/extract

You can also use the Midnight Commander (mc) utility to extract single files from tarballs or RPM packages.

Hi. Thanks for the feedback. However, it doesn't seem to be working for me :/ I tried this from SSH;

tar -xvf /home/linkssql/public_html/new/account/Thumb.tar Install.pm -C /home/linkssql/public_html/new/account/


Any ideas?

TIA.

Andy

cd /home/linkssql/public_html/new/account/
tar xvf Thumb.tar `tar tf Thumb.tar | grep 'Install.pm$'` -C .

maybe ...

what does:
tar tf Thumb.tar | grep 'Install.pm$'

give you?

Could this be run with one single PHP system() command though? As I originally said, I need it to do it in one command, otherwise I could just use;

cd /path/to/folder
tar -xof File.tar Install.pm

:-/

Cheers

What OS and version are you running? Try removing the - in front of xvf. It works fine on my Red Hat 9 box...


[root@nagios temp]# ls
nagiosconfigs.tar
[root@nagios temp]# tar xvf nagiosconfigs.tar cgi.cfg -C ./
cgi.cfg
[root@nagios temp]# ls
cgi.cfg nagiosconfigs.tar
[root@nagios temp]#

it could be it wants the full path of 'Install.pm' rather than just the filename.

Example.
[root b]# touch a
[root b]# tar cvf a a.tar
[root b]# tar cvf a.tar a
a
[root b]# mkdir b
[root b]# tar xvf a.tar -C b/
a
[root b]# cd b/
[root b]# ls -tr
a
[root b]#


However


[root /]# tar cvf c.tar /tmp/c
tar: Removing leading `/' from member names
tmp/c
[root /]#
[root /]# tar xvf c.tar -C /tmp/b/
tmp/c
[root /]# cd /tmp/b/
[root b]# ls -tlr
total 32
-rw-r--r-- 1 root root 10240 Sep 1 12:56 a
-rw-r--r-- 1 root root 20480 Sep 1 12:56 a.tar
drwxr-xr-x 2 root root 14 Sep 1 12:57 b
drwxr-xr-x 2 root root 14 Sep 1 12:59 tmp[root b]# cd tmp
[root tmp]# ls
c
[root tmp]# pwd
/tmp/b/tmp



See tar is quite stupid sometimes so it won't give you the results you need all the time.

Enjoy !

You typed it wrong. The command is....

tar zxvf tarball.tar.gz /filetoextract -C /where/to/extract

An even easier way to extract files from a tarball or RPM package is using the mc (Midnight Commander) utility. I thought the utility was completely useless up until recently. Try it out, type 'mc' in a virtual console and then search for a .rpm or .tar.
