If I had a perl string $newpw which is inputed by a user and it may
contain special characters such as '@' and '$' (e.g. "5a@Wf7$X"). How
to pass it to the system function properly?
This does not work:
system("/usr/local/bin/acthw -pw \"$newpw\"");
The simplest way would be to bypass the shell:
system '/usr/local/bin/acthw', '-pw', $newpw;
perldoc -f system
