What is commandlinefu?
Have you ever heard of "commandlinefu" website? Many developers and system administrators have been posing very convenient Linux commands. You should be able to find some great Linux commands on the website.You can search a part of Linux command or what you would like to do in the search box, so that you can get a list of Linux commands and its explanation.

However, when you are working on Linux terminal software, you may need to search a great Linux command, so you always need to switch to web browser to access the commandlinefu website, but if you are able to keep staying in the Linux terminal and search commandlinefu contents, that would be great.
Install commandlinefu search tool
Below is the tool's URL.https://github.com/samirahmed/fu
Installing the tool is very easy as follows.
$ git clone git://github.com/samirahmed/fu.git $ cd fu/ $ sudo make install
How to use the tool
It is easy to use the tool. You just need to type a keyword right after the "fu" command, so that the command shows a list of Linux commands and its explanation.For example, as a search keyword, I use "ssh" as follows. Once the search result is shown, you just need to copy and past the command, so you can run a great Linux command very easily.
$ fu ssh 1 # output your microphone to a remote computer's speaker dd if=/dev/dsp | ssh -c arcfour -C username@host dd of=/dev/dsp 2 # Mount folder/filesystem through SSH sshfs name@server:/path/to/folder /path/to/mount/point 3 # Compare a remote file with a local file ssh user@host cat /path/to/remotefile | diff /path/to/localfile - 4ms total:25I also searched with "windows" (this is not a Linux command), but it searches command explanation, as a result of that, it shows some commands.
$ fu windows 1 # Shutdown a Windows machine from Linux net rpc shutdown -I ipAddressOfWindowsPC -U username%password 2 # Convert PDF to JPG for file in `ls *.pdf`; do convert -verbose -colorspace RGB -resize 800 -interlace none -density 300 -quality 80 $file `echo $file | sed 's/\.pdf$/\.jpg/'`; done 3 # Save your sessions in vim to resume later :mksession!861ms total:25
By default, the "fu" command shows only 3 results, but if you need full results, you can add "-a" option, so that you can get all the search result.
$ fu -a ssh 1 # output your microphone to a remote computer's speaker dd if=/dev/dsp | ssh -c arcfour -C username@host dd of=/dev/dsp 2 # Mount folder/filesystem through SSH sshfs name@server:/path/to/folder /path/to/mount/point 3 # Compare a remote file with a local file ssh user@host cat /path/to/remotefile | diff /path/to/localfile - 4 # SSH connection through host in the middle ssh -t reachable_host ssh unreachable_host 5 # Copy your SSH public key on a remote machine for passwordless login - the easy way ssh-copy-id username@hostname 6 # Copy your ssh public key to a server from a machine that doesn't have ssh-copy-id cat ~/.ssh/id_rsa.pub | ssh user@machine "mkdir ~/.ssh; cat >> ~/.ssh/authorized_keys" 7 # Create a persistent connection to a machine ssh -MNf@ 8 # Remove a line in a text file. Useful to fix ssh-keygen -R 9 # Attach screen over ssh ssh -t remote_host screen -r 10 # directly ssh to host B that is only accessible through host A ssh -t hostA ssh hostB 11 # Synchronize date and time with a server over ssh date --set="$(ssh user@server date)" 12 # Duplicate installed packages from one machine to the other (RPM-based systems) ssh root@remote.host "rpm -qa" | xargs yum -y install 13 # Port Knocking! knock 3000 4000 5000 && ssh -p user@host && knock 5000 4000 3000 14 # run complex remote shell cmds over ssh, without escaping quotes ssh host -l user $( /dev/null" 22 # Tell local Debian machine to install packages used by remote Debian machine ssh remotehost 'dpkg --get-selections' | dpkg --set-selections && dselect install 23 # throttle bandwidth with cstream tar -cj /backup | cstream -t 777k | ssh host 'tar -xj -C /backup' 24 # Resume scp of a big file rsync --partial --progress --rsh=ssh $file_source $user@$host:$destination_file 25 # Single use vnc-over-ssh connection ssh -f -L 5900:localhost:5900 your.ssh.server "x11vnc -safer -localhost -nopw -once -display :0"; vinagre localhost:5900 5ms total:25
Again, you can stay in a LInux terminal and can search some great Linux commands. Let's install the "fu" command now!
