Find out which debian package a command (executable) belongs to on debian-based distros

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.

Alternatives

There are 5 alternatives - vote for the best!

Terminal - Alternatives
dpkg -S $( which ls )
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.

whichpkg() { rpm -qf "$@"; }
