Fix all the bad dates in your CPAN changes file and get it right with the formal specification. This code assumes your dates aren't so mangled that they can't be parsed by Time::ParseDate
cp Changes Changesx ; grep -P '^\d' Changes | perl -MTime::ParseDate -nE 'chomp; $_ =~ s/.*?\s//; $orig = $_; $_ = Time::ParseDate::parsedate( $_ ); ($sec,$min,$hour,$mday,$mon,$year,$wday,$yday,$isdst) = localtime( $_ ); $mon+=1; $year+=1900; say sprintf "%4d-%02d-%02d | $orig", $year, $mon, $mday;' | while read parseddate; do echo "$parseddate" | perl -MFile::Util -E '$file = shift @ARGV; $ftl = File::Util->new; $content = $ftl->load_file( $file ); undef $/; $swap = <>; chomp $swap; ( $good, $bad ) = split / \| /, $swap; $content =~ s/\Q$bad\E/$good/smg; $ftl->write_file( $file => $content )' Changesx; echo "$parseddate"; done
# the fixed file is in "Changesx"

Script to quickly scan the S.M.A.R.T. health status of all your hard drive devices in Linux (at least all the ones from /dev/sda to /dev/sdzz). You need smartctl installed on your system for this script to work, and your hard drives need to have S.M.A.R.T. capabilities (they probably do).
#!/bin/bash
# install the smartctl package first! (apt-get install smartctl)
if sudo true
then
true
else
echo 'Root privileges required'

This LSB-compliant Linux boot init script lets you auto-start VMware virtual machines on a Linux host machine running VMware Workstation. Tested successfully on Debian 7 and assumed safe for any Ubuntu or Ubuntu-based distro as well. May need some minor tweaks before you can use it on CentOS or RHEL.To use this script, follow installation instru…

Patch that makes suid binaries possible for App::PAR::Packer (pp), version 1.015 It will not work if you build it with the -c or --clean option when invoking pp. Crypto filters are still in bounds though and work well. My pp helper build script is below. You don't have to use it; it just makes things easier. Substitute filenames as desired. #!/b…
