Terminates the currently running Perl script and executes
the program named in command. The Perl program does not
resume after the
exec unless the
exec cannot be run and
produces an error.
system, the executed command is not forked off
into a child process. An
exec completely replaces the script
in its current process.
command may be a scalar containing a string with the
name of the program to run and any arguments. This string is
checked for shell metacharacters, and if there are any, passes
the string to
/bin/sh/ -c for parsing.
Otherwise, the string is read as a program command, bypassing any
shell processing. The first word of the string is used as the
program name, with any remaining words used as arguments.
command may also be a list value where the first element is parsed as the program name and remaining elements as arguments. For example:
Theexec 'echo', 'Your arguments are: ', @ARGV;
execfunction is not implemented for Perl on Win32 platforms.
