Read line by line in bash script

Question

I want to do the following, read line by line of a file and use the value per line as params

FILE=\"cat test\"
echo \"$FILE\" | \\
while read CMD; do
echo $C         


        

Answer 1

If you want to use each of the lines of the file as command-line params for your application you can use the xargs command.

xargs -a  

A params file with:

a
b
c
d

and the file tr.py:

import sys
print sys.argv

The execution of

xargs -a params ./tr.py

gives the result:

['./tr.py', 'a', 'b', 'c', 'd']
