    <p>I have a Perl script that does various installation steps to set up a development box for our company. It runs various shell scripts, some of which crash due to lower than required <code>ulimit</code>s (specifically, stack size <code>-s</code> in my case).</p> <p>Therefore, I'd like to set a <code>ulimit</code> that would apply to all scripts (<code>children</code>) started from within my main Perl one, but I am not sure how to achieve that - any attempts at calling ulimit from within the script only set it on that specific child shell, which immediately exits.</p> <p>I am aware that I can call <code>ulimit</code> before I run the Perl script or use <code>/etc/security/limits.conf</code> but I don't want the user to know any of this - they should only know how to run the script, which should take care of all of that for them.</p> <p>I can also run <code>ulimit</code> every time I run a command, like this <code>ulimit -s BLA; ./cmd</code> but I don't want to duplicate this every time and I feel like there's a better, cleaner solution out there.</p> <p>Another crazy "workaround" is to make a wrapper script called BLA.sh which would set ulimit and call BLA.pl, but again, it's a hack in my mind and now I'd have 2 scripts (I could even make BLA.pl call itself with "ulimit -s BLA; ./BLA.pl --foo" and act differently based on whether it sees --foo or not but that's even hackier than before).</p> <p>Finally, apparently I could install BSD::Resource but I'd like to avoid using external dependencies.</p> <p><strong>So what is <em>THE</em> way to set the ulimit from within a Perl script and make it apply to all children?</strong></p> <p>Thank you.</p>

    1. COjust use BSD::Resource. alternatively, compile your own XS module to do the same. don't know why you would do that, though.

A row detail

Detail views are divided into sections. All the information in the data section comes from columns in the selected row. The other sections display data from other, related rows.

Related data can be related in a to-one or a to-many fashion. Captions of data related in a to-many fashion link to a list view showing a filtered view of the table.

Try moving around until you find a non-empty to-many entry and click on the label to get to one. You can move back to the root by clicking on the database name in the header.
