Instead of relying on $$ to not collide with an existing path. Quoting the Bash manual about $$: > Expands to the process ID of the shell. In a () subshell, it expands > to the process ID of the current shell, not the subshell. So, this is different from $BASHPID: > Expands to the process ID of the current bash process. This differs > from $$ under certain circumstances, such as subshells that do not > require bash to be re-initialized. But even $BASHPID is prone to race conditions if the process IDs wrap around, so to be on the safe side, we're using mktemp here. Closes #3784. Signed-off-by: aszlig <aszlig@redmoonstudios.org> |
