cd a
tar xvf files.tar a
It gives the error like
tar: files.tar: No such file or directory

Dear Anjaneyulu,

where you are going take a backup for using tar.

for examble u use the below method.

login to the home directory.

cd /home
home> tar -cvf files.tar 1 2 a

it's stored in the same home directory.like files.tar and remove it the exitsting directory.

then,

home> tar -xvf files.tar a

it will restore the mentioned directory.

u try this and revert back.....

Regards,
Unixguy.

Hi Anjaneyulu,

here the steps to follow.
tar options (destination) (source)
#tar cvf file.tar 1 2
#cd a
#tar xvf file.tar .

[Anjaneyulu]

I followed your commands.

But it shows same error.

I want to copy the files from /home/anji to a1 directory

After you did 'cd a'. you don't have to again specify 'tar xvf file.tar a'. Just specify 'tar xvf files.tar' (inside 'a' dir)

[Anjaneyulu]

$ tar xvf file.tar
tar: file.tar: No such file or directory

It gives above error in dirctory a.

Hi Anjaneyulu,

>>>I want to copy the files from /home/anji to a1 directory<<

First copy all the files from /home/anji and stored in /tmp/anji.tar

#tar -cvf /tmp/anji.tar /home/anji

Now goto the directory wherever you want to restore. Then extract the file.

#cd /tmp/a
#tar -xvf /tmp/anji.tar

It will restore all the files in /tmp/a directory.

Hi Anjaneyulu,

Better u login to that directory.

cd /home/anji

home/anji> tar * files.tar

then that a1 directory is in home,login into a1.

home/anji>cp files.tar /home/a1

cd ..

cd a1

home/a1> tar -xvf files.tar

Hope now u r understood.

you must not reside in the directory where you wanna restore files.

don't cd to a directory

cd to previous directory from where you taken the tar files and run command

#tar xvf files.tar a/

[Wim Rombauts]

Well, it's very simple :

tar cvf files.tar 1 2 a
cd a
tar xvf ../files.tar a

Since you create "files.tar" in the local directory and then do "cd" to a subdirectory, you have to go to the directory above to find your tar file.

[Venkatesh BL]

> tar cvf files.tar 1 2 a

As 'a' is the destination directory, that should not be specified during 'archival'

Example:

# ls
a.c a.out a1 a1.c a2 a2.c aa.c test
# tar -cvf a.tar a.c a1.c
a a.c 4 blocks
a a1.c 2 blocks

# mkdir xyz
# ls xyz
# mv a.tar xyz
# cd xyz
# tar -xvf a.tar
x a.c, 1631 bytes, 4 tape blocks
x a1.c, 781 bytes, 2 tape blocks
# ls
a.c a.tar a1.c

Hi,

'tar cvf files.tar 1 2'
'mv files.tar a'
'cd a'
'tar xvf files.tar'

OR simply:

'mv 1 a'
'mv 2 a'
'cd a'

OR

'tar cvf a/files.tar 1 2'
'cd a'
'tar xvf files.tar'

Hi ,

Pls try to understand the below ex.

1)tar - cvf /tmp/file.tar /home/pr/A/*
suppose i m going to diff directory
cd /home/qt
and run the below command
tar - xvf /tmp/file.tar
it will extarct the file in /home/xospnw01/A
============================================
now second example
cd /home/pr/A
tar - cvf /tmp/file.tar ./*
cd /home/qt
tar -xvf /tmp/file.tar
it will extact the file in /home/qt

==============================
If u r using the absolute path for doing the tar then u can extarct in the same path only.
=================================
if u r using relatve path for taring then u can exatrct in any path.

Hope u will underastand the concept

Why didn't you say so at the beginning?

mkdir a # If needed.
( cd /home/anji ; tar cf - . ) | \
( cd a ; tar xf - )

There's no real need to create a "files.tar".

[Prashanth Waugh]

Hi ,
small correction here

1)tar - cvf /tmp/file.tar /home/pr/A/*
suppose i m going to diff directory
cd /home/qt
and run the below command
tar - xvf /tmp/file.tar
it will extarct the file in /home/pr/A

steven's solution is right on target...

and, of course, an example of that solution can be found in "man tar", had the original poster read it.
