Otherwise, without the execute permission but with read permission you can

Code:
ksh original.sh

by the way if you put
Code:
#!/usr/bin/ksh

as a first line, it might be a good idea to name it
Code:
original.ksh

instead ...

Thank again,

What should i do if I want to to remove the #, I have tried coule of things on the sed you've told me, however it didnt work.


Now if I have sth like

echo "a"
#echo"b"
echo "c"



when I tried I ended up deleting everything until the word I've searched;

echo "a"
b"
echo "c"

but I want to have

echo "a"
echo"b"
echo "c"
