Hello Aditya121,

Could you please try following command for same.

Code:

find -maxdepth 1 -type f | awk '{sub(/\.\//,X,$0);print "tar -cvf " $0".tar " $0}'

If you are happy with the results of above command then kindly use following script and let me know if this helps.

Code:

cat move_tar_files.ksh
find -maxdepth 1 -type f | awk '{sub(/\.\//,X,$0);print "tar -cvf " $0".tar " $0}' | sh
find `pwd` -maxdepth 1 -type f -exec sh -c  'mv -v "${0}" target_directory' {} \;

NOTE: I have used -maxdepth 1 which means it will only look for current directory's files not inside of directories on present directory.
Also I am trying to do it within single find command, will let you know if I get that done.

Thanks,
R. Singh

Hello aadiya321,

Please note that when we willl run the find command as follows.

Code:

find -maxdepth 1 -type f

It will provide us output as follows.(Just some example files in my system.)

Code:

./get_data
./bcd.txt
./abc.txt
./testtest1
./check420
./check13
./check2

So in order to remove ./ before filenames I have used that expression, whose explaintaion is as follows.

Code:

sub(/\.\//,X,$0)  #### sub is the utility in awk to perform substitution operation in 
                          ####sub(pattern or regular expression, substitue with string/var, in string). 
                          ####So match ./(which I have escaped here by \as they are Meta characters here) then substitute them with 
                          ####a variable named X(which has NULL value) and perform this on $0 means whole line.

Hope this helps.

Thanks,
R. Singh

How about simple pax :

Code:

cd /home/admin
pax -d -rw * /dis/wis

This will not traverse the directories (-d) but they will be copied.
Also it will not match .files or .directories, you will need to match those separately, with another pax or shell regex.

Alternatively, if you want to archive and copy your entire home with sub directories and everything use :

Code:

cd /home/admin
pax -rw . /dis/ws

After the pax command you can use rm to remove old files.

Hope that helps.

Peasant.

Not sure what exactly you want to achieve. tar by itself will backup the entire tree that it is pointed to, you can exclude files and directories if need be, and then, if /dis/wis is on the same file system as /home/admin, a simple rename (mv) should suffice...?
