From Independent routines
(Independent routines) sub chmod
Defined as:
sub chmod(Int() , * --> List)
Coerces all @filenames
to IO::Path
and calls IO::Path.chmod
with $mode
on them. Returns a List
containing a subset of @filenames
for which chmod
was successfully executed.
chmod 0o755, <myfile1 myfile2>; # make two files executable by the owner
class IO::Path
From IO::Path
(IO::Path) method chmod
Defined as:
method chmod(IO::Path: Int() --> Bool)
Changes the POSIX permissions of a file or directory to $mode
. Returns True
on success; on failure, fails with X::IO::Chmod.
The mode is expected as an integer following the standard numeric notation, and is best written as an octal number:
'myfile'.IO.chmod(0o444); # make a file read-only'somedir'.IO.chmod(0o777); # set 0777 permissions on a directory
Make sure you don't accidentally pass the intended octal digits as a decimal number (or string containing a decimal number):
'myfile'.IO.chmod: '0444'; # BAD!!! (interpreted as mode 0o674)'myfile'.IO.chmod: '0o444'; # OK (an octal in a string)'myfile'.IO.chmod: 0o444; # Also OK (an octal literal)
