xargs vs exec with find:

Hi All,

i'm trying to create a tar of all the .txt files i find in my dir . I've used xargs to acheive this but i wanted to do this with exec and looks like it only archives the last file it finds . can some one advice what's wrong here :

Code:

find . -type f -name "*.txt" -print0 | xargs -0 tar -cf txtarchive.tar

$ tar -tvf txtarchive.tar
-rw-r--r-- user/None  123 2012-06-30 17:39 ./employe.txt
-rw-r--r-- user/None   18 2012-07-04 12:59 ./file.txt
-rw-r--r-- user/None    5 2012-07-04 12:59 ./file2.txt
-rw-r--r-- user/None   13 2012-07-14 14:34 ./files.txt
-rw-r--r-- user/None   72 2012-07-12 14:12 ./filesfound.txt
-rw-r--r-- user/None 4938 2012-07-05 09:53 ./sql.txt
-rwxrwxrwx user/None    6 2012-02-15 16:35 ./users.txt

the same action but using exec:

Code:

$ find . -type f -name "*.txt" -exec tar -cvf archivetxt1.tar '{}' \;
./employe.txt
./file.txt
./file2.txt
./files.txt
./filesfound.txt
./sql.txt
./users.txt

$ tar -tvf archivetxt1.tar
-rwxrwxrwx chaitanya/None    6 2012-02-15 16:35 ./users.txt

can some advice whats wrong with my usage of exec here ?

cheers

X2SYS_MERGE(1gmt)					       Generic Mapping Tools						 X2SYS_MERGE(1gmt)

NAME

       x2sys_merge - Merge an updated COEs tables

SYNOPSIS

       x2sys_merge -Amain_COElist.d -Mnew_COElist.d

DESCRIPTION

       x2sys_merge  will read two crossovers data base and output the contents of the main one updated with the COEs in the second one. The second
       file should only contain updated COEs relatively to the first one.  That is, it MUST NOT contain any new  two  tracks  intersections  (This
       point  is  NOT checked in the code). This program is useful when, for any good reason like file editing NAV correction or whatever, one had
       to recompute only the COEs between the edited files and the rest of the database.

       -A     Specify the file main_COElist.d with the main crossover error data base.

       -M     Specify the file new_COElist.d with the newly computed crossover error data base.

OPTIONS

       No space between the option flag and the associated arguments.

       EXAMPLES
	      To update the main COE_data.txt with the new COEs estimations saved in the smaller COE_fresh.txt, try

	      x2sys_merge -ACOE_data.txt -MCOE_fresh.txt > COE_updated.txt
