That does not sound correct. According to your description ftp will
not run until the tar is complete.

Now that will cause problems because the & will cause control to
return to ftp before the tar is complete.

Ok, kick off all the tars, and create a loop which will watch for the
last tar to complete.

man pgrep


You can use the return code from pgrep to control the while/until
loop to know when all the tars are complete.

loop syntax can be found at

Greetins,

Im trying to achieve the following thing :

tar cz /somedir -f somedir.tgz
then put via ftp somedir.tgz to a remote server.

I can do all this with no pb on command line.

When i make it via script, it tries to ftp the file while it is still
under construction -> file not found.

I could do it like this :
tar cz /somedir -f somedir.tgz &
ftp

but I tar several files in several archives and need to transfer all of
them then "rm" them.

Can someone tell me how can I make bash wait for tar processes to be done ?

thank you !
