UNIX for Dummies Questions & Answers

Hi all!

I'm writting one script to copy a file in various folders, but there are 2 things to validate. First that the folder where i'll be cpying exists, and second that i have permissions to copy the file in it.
so far i have found the way to validate the folder exists, but when trying to copy it, don't know how to validate if it was copied, since if I don't have permission to see the folder i wont be able to do ls | wc -l
this is the code:

Code:

if  [ -d $UIXMLDEVENG ] ; then
   echo 
else
   echo "PATH $UIXMLDEVENG does not exist">FinalLog.log
   exit 0
fi

cp $PRUEBA $UIXMLDEVENG

how to validate either the folder is there and have permissions not only to see it but also to copy a file inside of it???

Thanks!!!

Have you thought to change the permission of the file so you can read it?

chmod +r File

then cat into it.

I can't with the user i'm logged, the idea it's not to read a file, sorry if I didn't make myself clear, the idea is to evaluate if the destiny folder is available, and if so, if I have permissions to copy a file inside.
Thanks anyway Shaun.

ls -al

look for file, see the chmod on left? See if you have the permissions. If the file does not appear, it is not available. At least not in that directory. Can you get into su? if not, and you are not the file owner - I cant help you.

If i understood correctly..

Check man test :

Code:

      -w FILE
              FILE exists and write permission is granted

Code:

$ls -dl test
dr-xr-xr-x 2 user group 4096 2011-05-01 08:32 test
$test -w test
$echo $?
1
$chmod 655 test
$ls -dl test
drw-r-xr-x 2 user group 4096 2011-05-01 08:32 test
$test -w test
$echo $?
0

Thank you very much! It worked just fine!

Now, another issue, how to do the same validation on a file which is in a remote server, using the same shell script??, maybe by using telnet, ssh or even ftp???
how could it be possible?
Thanks!!!

Code:

ssh USERNAME@SERVERNAME "the command"
