This revision to my command (command #8851) was called for when it failed to find the parent

package of 'rlogin', which is really a deep symbolic link to /usr/bin/ssh.

This revision fixes this newfound issue, while ensuring fixes of other older issues work too.

apt-file search iostat
whichpkg () { dpkg -S $1 | egrep -w $(readlink -f "$(which $1)")$; }

Advanced revision to the command 8776 . This revision follows symbolic links.

The quotation-marks surrounding $(which $1) allows for graceful handling of errors ( ie. readlink does not complain incase 'which' command generates (null) output)

function whichpkg { dpkg -S $1 | egrep -w $(which $1)$; }

Similar to command 7822, but handles errors gracefully.

+1 for this command

This is useful on rpm based systems like RedHat/SuSE/CentOS. I wonder if this was voted down by the Debian/Ubuntu folks? The dpkg alternatives don't work on rpm systems. +1 from me for the "rpm -qf" part. I'm not sure you need a function (or alias) for it, but either way it's useful and unfairly voted down.
