File Permissions

I am running Perl on an AIX box and have written a script that automatically  creates a file should the file be removed / deleted etc.  However when the file is created it inherits only the read / write permissions of the user who ran the script at that time.

Is there any way I can overide this and set global permissions to this file as everyone uses the script?????

sure you can do that.

you can embed the following command in you PERL script right after you have closed the file


open(FILE,">file.txt") || die $!;

###Do some file write...


`chmod 775 $yourfile`;
If you want to avoid launching an external process you can use the perl command "chmod" like so:

Here's how to change the permissions of fred and barney while checking the errors for each:

foreach $file ("fred","barney") {
  unless chmod (0777,$file) {
  warn "hmm... couldn't chmod file.$!";
