I use this code in gnu screen's statusbar:

backtick 1 1 1 sh -c 'perl -ne "/^(la|re|st)[^:]+:\s+(\S+)\s/and \$h{\ +$1}=\$2}{\$h{st}=~s/of.*/-/;\$h{st}=~s/on.*/+/;printfq(%.0f%%%s),\$h{ +re}*100/\$h{la},\$h{st}" /proc/acpi/battery/BAT0/* /proc/acpi/ac_adap +ter/ACAD/state'

[Lady_Aleena]: shmem, that is understandable! The two examples in File::Find don't make sense to me on a quick glance.
[marioroy]: LA if the find worked from Unix command line, or does it not. Likely a quoting issue inside Perl qx.
[Lady_Aleena]: marioroy, the find worked fine at the command line.
[marioroy]: LA, yeah. than there's no reason why it cannot work inside qx. But chatting is hard in PM. I cannot see the code now.
[shmem]: Lady_Aleena: sometimes a quick glance isn't enough.
