how to extract single Folder / File from .tar.gz

[zaji_nms]

Dear Expert

I am cracking my head but no success.

there are three question as below

how to view tar.gz to view files (all files including rrd xml) I tried as below but no success (not showing any rrd/xml files)

tar -ztvf nagiosxi.123456789.tar.gz

how to extract one full folder of /usr/local/nagios/share/perfdata/mydevice-7600/

how to extract single file /usr/local/nagios/share/perfdata/mydevice-7600/GigabitEthernet0_2.1234_Bandwidth.rrd

regards

Assuming nagiosxi.123456789.tar.gz is the backup file, run

Code: Select all

backupfile=/store/backups/nagiosxi/nagiosxi.123456789.tar.gz

to extract a dir

Code: Select all

tar -xzOf $backupfile $(basename $backupfile .tar.gz)/nagios.tar.gz | tar -xzf - usr/local/nagios/share/perfdata/mydevice-7600

to extract the file

Code: Select all

tar -xzOf $backupfile $(basename $backupfile .tar.gz)/nagios.tar.gz | tar -xzf - usr/local/nagios/share/perfdata/mydevice-7600/GigabitEthernet0_2.1234_Bandwidth.rrd

These files/directories will be placed in their path under where you are running the command, so if you run this from your home directory you would be able to view the file as:

Code: Select all

ls -l ~/usr/local/nagios/share/perfdata/mydevice-7600/GigabitEthernet0_2.1234_Bandwidth.rrd

i think it will work in two section basefile and then redirect as you mentioned in your solution

also can you please reply (solution) if i want to list files/folder

with FULL PATH
without FULL PATH (just filenames)

[scottwilkerson]

The backup actually contains what you showed, but it contains several other tar.gz files.

[scottwilkerson]

So for example to view the file in the inside nagios.tar.gz you could run

Code: Select all

tar -xzOf $backupfile $(basename $backupfile .tar.gz)/nagios.tar.gz | tar -ztvf -

[zaji_nms]

great its working fine

hopefully now last question in this thread...sorry to bother u....but may be useful for some time some user

its showing full path, how to do some trick with awk/sed to....

list only folders with PATH
list only folders without PATH
list only files without FULL PATH

Regards

[vtrac]

Here are couple examples:
list only folders with PATH (sort uniq):

Code: Select all

tar -zttf filename.tar.gz | awk '{print $6}' | sed  's/\(.*\/\)\(.*$\)/\1/g' | sort -u

list only files without FULL PATH:

Code: Select all

tar -zttf filename.tar.gz | awk '{print $6}' | sed  's/.*\///g'

Best Regards,
