what am i doing wrong
#!/bin/bash
$1 | cat >> - $2

I am trying to write a script that takes that takes two arguments. The first being a line of text, the second being a file you create. The script should take the first argument and insert it into the very top (the first line) of the file named in your second argument

Cant see whats wrong with the above. Anyone any clues.

Code:
#!/bin/bash
echo $1 | cat - $2

This will output the first arg followed by the contents of the file named in the second arg on screen.

Try this :

cp $2 $2_temp
awk -v val1=${1} -F , 'BEGIN {
print val1
}' > temp

cat temp $2_temp > $2
rm temp $2_temp
