Looking at your code, it looks like you are attempting to run a for loop, in simplified form it is:

system($_) for @command_list;

Without the if statements on the ends of some lines, everything is fine, and it does not matter what form of quoting you use to define the commands in your list.

However, when you add the if statement on the end of some lines, then it is syntax error, as you are trying to nest two things where they can't be nested.

There are two ways you could rewrite this. You could build the command list, by conditionally adding elements to it:

my @cmd_list;
push @cmd_list, qq(p4 sync -k "$options{v}");
push @cmd_list, qq(p4 -x "$options{f}" delete) if (exists $options{f})
+;

# ... etc.

system $_ foreach @cmd_list;

Or you could just run the commands conditionally:

system qq(p4 sync -k "$options{v}");
system qq(p4 -x "$options{f}" delete) if (exists $options{f});
# ... etc.
