linux - Perl script, how to source an environment variables from .bash_profile -

-

i need quick advice on perl script. created script calls other perl scripts , many other shell scripts within those. problem i'm facing, trying make run on universal level setting 1 environment variable.

this on linux rhel/centos way...

so add variables .bash_profile , works without issue if manually source file first, run perl script! is, ok, script automate part instead of needing extra, manual sourcing step.

so script looks this... in short

#!/usr/bin/perl use warnings; use strict;  `/bin/bash ~/.bash_profile`;  blah blah blah more code etc;

when launching main script (where part of code is) works no problem. it's subsequent calls made other scripts failing...as if not passing variable on rest of scripts.

any ideas??

thanks,

  • the easiest way set environment variables within perl $env{"name"}=.... these variables propagated automatically programs started within perl script, no matter if perl or shell scripts
  • alternatively open .bash_profile, parse within perl, extract variables , set them again within perl $env. error prone because there might several ways declare variables.
  • or spawn shell, reads .bash_profile , calls env afterwards. read , parse output shell. similar previous proposal, output have parse more defined.
  • or use shell script sources .bash_profile , spawns perl script.

php - render data via PDO::FETCH_FUNC vs loop -

-
i've been using 2 methods render data. the first one: function name($id,$name){ return '<div id="'.$id.'">'.$name.'</div>'; } echo implode($pdo->query("select id,name user")->fetchall(pdo::fetch_func,'name')); the second one: $users = $pdo->query("select id,name user")->fetchall(pdo::fetch_obj); foreach($users $user){ echo name($user->id,$user->name); } i don't understand how pdo::fetch_func works. tried figure out. however, not well-documented. could please explain fetch mode? , also, 1 performs better? thank you. both methods wrong , have learn how use templates , how separate business logic presentation logic. $users = $pdo->query("select id,name user")->fetchall(pdo::fetch_obj); tpl::assign('users', $users); is code business logic part. then in template <?php foreach $users $row): ?> <div id="<?=$...
