Adding a Fileinput loop to exsiting script.

Shell Programming and Scripting
1

:confused: I'm very confused on what I need to do. I've looked at if, while, but I can't seem to visualize where in my current script to put the commands.
I'm looking to read a directory /ERD/iface/data/ocom/citi/idd because there will be multible files, but I need to process them one at a time. The Process is copy the file, encrypt the file, send the file, delete the file. How do I loop this? Thank you VERY much.

To keep the forums high quality for all users, please take the time to format your posts correctly.

First of all, use Code Tags when you post any code or data samples so others can easily read your code. You can easily do this by highlighting your code and then clicking on the # in the editing menu. (You can also type code tags

```text
 and 
```

by hand.)

Second, avoid adding color or different fonts and font size to your posts. Selective use of color to highlight a single word or phrase can be useful at times, but using color, in general, makes the forums harder to read, especially bright colors like red.

Third, be careful when you cut-and-paste, edit any odd characters and make sure all links are working property.

Thank You.

Example for loop that print all the files insede directory /ERD/iface/data/ocom/citi/idd

for name_file in `ls /ERD/iface/data/ocom/citi/idd`
do
   echo $name_file
done
