Help with a simple function
Hi there

Everytime it calls the second if statement it keeps calling the first echo message from the first if statement.

how do I get it to display the second echo message in the second if statement?

Thanks.


Code:
function (verbose) { 

if [ "args_V" = v" ] ; then 
echo "rm: cannot remove $1 : is a directory"

elif [ "$args_V" = "v" ] && [ -f "$1" ] ; then 
echo "removed \`$1'"

if [[ "$args_V" = "v" &&  "$args_I" = "i" &&  "$args_R" = "r" ] then
interactive $1

fi 
fi 
}

There are syntactical problems with your snippet. The function name cannot have parentheses, on the second line there is a double quote missing. I suggest you have another look at the syntax...

And still there is a double quote missing on line 2 (and a $-sign?)

Since elif is being used, the second condition does not get evaluated when condition 1 is true, and it always evaluates to false when condition 1 is false, so condition 2 never becomes true.....

Oh i see however the second condition (elif) does evaluate so in this case it does remove the file but it doesn't execute the second echo statement. What can i do to fix this?
