Question

If i run this command in linux command line manually it works, and EDIT.3126026369 is not empty

curl "http://somesite.com/admin.php?mod=editnews&action=editnews&id=14058" -s -L -b cookie.ck -c cookie.ck > EDIT.3126026369

in bash:

curl \"$EDIT\" -s -L -b $COOKIE -c $COOKIE > EDIT.$TEMP

but in a bash script it generate an empty file. what am missing here?

Answer 1

Use the quotes when defining your $EDIT variable:

EDIT="http://somesite.com/admin.php?mod=editnews&action=editnews&id=14058"

Then lose the escaped quotes on the curl command:

curl $EDIT -s -L -b $COOKIE -c $COOKIE > EDIT.$TEMP

Seems to work fine for me this way, how about you?

Answer 2

What's in your $EDIT variable, and do you need to quote it like that? If it's your URL, I would simply expect you to write

curl $EDIT ....

If you run your bash script with a -x option, it'll show you each line that it executes. That's a very useful debugging technique.
