May 19, 2015 - A Look At The New Commandlinefu
I've put together a short writeup on what kind of newness you can expect from the next iteration of clfu. Check it out here.

I'm Jon, I'll be maintaining and improving clfu. Thanks to David for building such a great resource!

Psst. Open beta.

Wow, didn't really expect you to read this far down. The latest iteration of the site is in open beta. It's a gentle open beta-- not in prime-time just yet. It's being hosted over at UpGuard (link) and you are more than welcome to give it a shot. Couple things:

  • » The open beta is running a copy of the database that will not carry over to the final version. Don't post anything you don't mind losing.
  • » If you wish to use your user account, you will probably need to reset your password.
Your feedback is appreciated via the form on the beta page. Thanks! -Jon & CLFU Team

Some command names are very different from the name of the package that installed them.

Sometimes, you may want to find out the name of the package that provided a command on a system, so that you can install it on another system.

If, for example, you want to remove all kernels and headers but the last three versions, you can't use one of that magic all-in-one "remove old stuff" commands.

With this simple but elegant command you can remove a range of versions, or a list of versions with e.g. {14,16,20}.

transfer() { basefile=$(basename "$1" | sed -e 's/[^a-zA-Z0-9._-]/-/g');curl --progress-bar --upload-file "$1" "https://transfer.sh/$basefile"|xsel --clipboard;xsel --clipboard ; }

access to the internet(http://transfer.sh)

This is an alias utilizing the transfer.sh service to make sharing files easier from the command line. I have modified the alias provided by transfer.sh to use xsel to copy the resulting URL to the clipboard.

The full modified alias is as follows since commandlinefu only allows 255 characters:

transfer() { if [ $# -eq 0 ]; then echo "No arguments specified. Usage:\necho transfer /tmp/test.md\ncat /tmp/test.md | transfer test.md"; return 1; fi if tty -s; then basefile=$(basename "$1" | sed -e 's/[^a-zA-Z0-9._-]/-/g'); curl --progress-bar --upload-file "$1" "https://transfer.sh/$basefile" |xsel --clipboard; else curl --progress-bar --upload-file "-" "https://transfer.sh/$1" |xsel --clipboard ; fi; xsel --clipboard; }

You can search for CVEs at https://security-tracker.debian.org/tracker/ or use --report to get full links. This can be added to cron, but unless you're going to do manual patches, you'd just be torturing yourself.

apt-cache pkgnames linux-
2014-12-14 06:48:57
User: benjabean1
Functions: apt

In this case, linux- is the prefix; simply running

apt-cache pkgnames

would list every package APT knows about.

The default APT config assumes -g, --generate; to use the cache as/is, you could similarly run:

apt-cache --no-generate pkgnames [prefix]

Adding --all-names, like so:

apt-cache --no-generate --all-names pkgnames [prefix]

would print all the packages APT knows about, using the cache as/is, including virtual packages and missing dependencies.

This command was shamelessly stolen from the apt-cache(8) man-page.

apt-get update && apt-get dist-upgrade -y --show-progress && apt-get autoremove -y && apt-get check && apt-get autoclean -y

# AllInOne: Update what packages are available, upgrade to new versions, remove unneeded packages

# (some are no longer needed, replaced by the ones from ap upgrade), check for dependencies

# and clean local cached packages (saved on disk but not installed?,some are needed? [this only cleans unneeded unlike ap clean]).

# aliases (copy into ~/.bashrc file):

alias a='alias'

a ap='apt-get'

a r='ap autoremove -y'

a up='ap update'

a u='up && ap upgrade -y --show-progress && r && ap check && ap autoclean'

# && means "and run if the previous succeeded", you can change it to ; to "run even if previous failed".

I'm not sure if ap check should be before or after ap upgrade -y, you can also change the alias names.

# To expand aliases in bash use ctrl alt e or see this ow.ly/zBKHs

# For more useful aliases go to ow.ly/zBMOx

If you run dpkg --clear-selections or have otherwise selected installed packages for deinstall, but want to undo it, run this. It will set all installed packages back to installed status so that they won't be removed by commands like "dpkg -Pa"

% sudo yum remove streams-$(uname-r)
dpkg-query -Wf '${Installed-Size}\t${Status}\t${Package}\n' | sort -n | grep installed
dpkg-query --show --showformat='${Package;-50}\t${Installed-Size}\n' `aptitude --display-format '%p' search '?installed!?automatic'` | sort -k 2 -n | grep -v deinstall | awk '{printf "%.3f MB \t %s\n", $2/(1024), $1}'

The other commands were good, but they included packages that were installed and then removed.

This command only shows packages that are currently installed, sorts smallest to largest, and formats the sizes to be human readable.

salt -G 'os_family:Debian' cmd.run 'apt-get dist-upgrade --dry-run | grep ^Inst | cut -d" " -f2'
salt -G 'os_family:Debian' cmd.run ' /usr/lib/update-notifier/apt-check --human-readable'

Functions: awk cut grep md5sum sed xargs

This functionality seems to be missing from commands like dpkg. Ideally, I want to duplicate the behavior of rpm --verify, but it seems difficult to do this in one relatively short command pipeline.

apt-popcon() { (echo \#rank; apt-cache search "$@" |awk '$1 !~ /^lib/ {print " "$1" "}') |grep -Ff- <(wget -qqO- http://popcon.debian.org/by_inst.gz |gunzip); }

Functions: apt awk echo grep wget

This will take the packages matching a given `apt-cache search` query (a collection of AND'd words or regexps) and tell you how popular they are. This is particularly nice for those times you have to figure out which solution to use for e.g. a PDF reader or a VNC client.

Substitute "ubuntu.com" for "debian.org" if you want this to use Ubuntu's data instead. Everything else will work perfectly.
