issue with grep command

[Jul]

in tcsh terminal i have the following line of code

cat fileName.txt | grep "a"

which extracts all the instances of "a" from the file in the
terminal..

however when i am trying to create a txt while, i am unable to do so
for some reason..this is the syntaxt i am using --

cat fileName.txt | frep "a" > a.txt


file then appears in the folder, however, it can no be opened because
"the file is not in the right format"..

does anybody know how to correct this problem?

thanks so much

thats what i have so far --

#!/usr/bin/python

import os.path

#open up the file
formisanoOpen = open("formisano_num.txt", "r")

#read in all the data into a list
readData = formisanoOpen.readLines()

#set up a sum
sum = 0;

#begin a loop
for trial in readData:

#the next line is indented (YA doesn't indent)
sum += int(trial)

#loop is over, so unindent
#report the sum
print sum


end

but it doesnt want to run for some reason
