Shell Programming and Scripting

Hi guys,

I am really newbie of csh and I am stuck with a script.

Basically what I want to do is assign to a variable (array) the output of "ls". Then look at this array and if there is the word "my_file", delete it from the array and echo the new array.

Moreover, I would like to have that every single item of my array is the input of a program.

Well I am stuck with both things. This is what I thought:

Code:

#!/bin/csh

set list=`ls *.img`

echo  -n "Name of your final dataset:"

set y = $myfile (the item that I want to remove from the array)

foreach i ($list)
if ($i =~ $y) then		
unset ${list[$i]}	
echo $list
/my_program <<EOF
$i
data
EOF

endif

I don't know how to find the index of an item in the list and delete exactly that item.

Please help...

Thanks guys.
