Shell Programming and Scripting

Hi All,

I have a requirement to search 3 files in a directory and process them after they arrive. I know the names of the files and also the directory where I have to search them. These things are going to be constant.

I used the "test -f" command to search a single file. That is working fine.

while ( test ! -f $P_DATA_FILE_PATH/$P_DATA_FILE_NAME)
do
sleep 10
done

The code above searches the file until it arrives. Now I want to check existence of 3 files & process each file separately when it arrives. I tried using the logical OR (||) by giving ( test ! -f $P_DATA_FILE_PATH/$P_DATA_FILE_NAME) || ( test ! -f $P_DATA_FILE_PATH/$P_DATA_FILE_NAME1) condition. But it does not work.

Can somebody help?

Bourne shell syntax:

Code:

$  [ condition1 -o condition2 ]

Korn shell syntax:

Code:

$  [[ condition1 || condition2 ]]

Regards
