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

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?

To clarify, if you enter those 2 commands I highlighted into a bash prompt it doesn't work ? (well, COOKIE and TEMP would need to be defined too I suppose... but you get where I'm going, trying to figure out how what you're doing is different than me...)

no if i run curl somesite.com/… -s -L -b $COOKIE -c $COOKIE > EDIT.$TEMP it's ignoring everything after the ampersand [1]+ Done curl somesite/admin.php?mod=editnews

if i run curl "somesite.com/…" -s -L -b $COOKIE -c $COOKIE > EDIT.$TEMP it works...

basically i need quotes for the ampersand in my link, but adding quotes in bash script doesn't work.

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.

the url link...the first command is an actual output from echo "curl \"$EDIT\" -s -L -b $COOKIE -c $COOKIE > EDIT.$TEMP" and i added quote because it contains ampersand in the link
