Shell Programming and Scripting

{Hello All,
Here is what I am trying to do:


I have an archive file: AppName.ear

Code:

jar -tvf AppName.ear
 60459 Thu May 01 09:29:36 EDT 2008 /SharedResources/Application/App.dat
 67542 Thu May 01 09:29:36 EDT 2008 JDBCConn/Application/App.dat
 14488 Thu May 01 09:29:36 EDT 2008 config.xml

what I am doing is, converting the ear file to a directory with files/dirs in the ear file in it, to under that directory.

Code:

EARFILE="AppName.ear"
DIRNAME="$EARFILE"
mv $EARFILE $EARFILE.tmp
unzip $EARFILE.tmp $DIRNAME

Code:

Output:
# ls -lrt AppName.ear
total 32
-rw-r--r--   1 root     other      14488 May  1 09:29 config.xml
drwxr-xr-x   3 root     other        512 May 21 14:25 SharedResources
drwxr-xr-x   3 root     other        512 May 21 14:25 JDBCConn

But the problem is, if an entry starts with / in the ear file(SharedResources), I have to create the directory as __SharedResources.

I am able to get till getting the entries of the ear file,
for i in `jar -tvf AppName.ear | awk {'print $8'}`; do echo $i; done

but how do I look for the files/dirs starting with / and replace it with __ ?

Thanks,
Chiru
