Quickly add a new user to all groups the default user is in

This is a standard procedure for me, whenever I set up a new Raspberry Pi system. Because the default user is "pi", I quickly replace it with my own (e.g. "kostis"), but I have to substitute that user to all of pi's groups first, before deleting the default account. xargs helps a lot with that in a single line, while avoiding boring "for" loops. For everything trickier, there's always "parallel" :)
This is sample output - yours may be different.

groups pi | xargs -n 1 | tail -n +4 | xargs -n 1 sudo adduser kostis

Clean up after a poorly-formed tar file

These days, most software distributed in tar files will just contain a directory at the top level, but some tar files don't have this and can leave you with a mess of files in the current folder if you blindly execute tar zxvf something.tar.gz This command can help you clean up after such a mistake. However, note that this has the potential to do bad things if someone has been *really* nasty with filenames.
This is sample output - yours may be different.

tar ztf tar-lacking-subdirectory.tar.gz | xargs rm

get diskusage of files modified during the last n days

get diskusage of files (in this case logfiles in /var/log) modified during the last n days: sudo find /var/log/ -mtime -n -type f | xargs du -ch n -> last modified n*24 hours ago Numeric arguments can be specified as +n for greater than n, -n for less than n, n for exactly n. => so 7*24 hours (about 7 days) is -7 sudo find /var/log/ -mtime -7 -type f | xargs du -ch | tail -n1 Show Sample Output

$ sudo find /var/log/ -mtime -7 -type f | xargs du -ch | tail -n1

Counts number of lines (in source code excluding comments)

I took java to make the find command simpler and to state that it works for any language supported by cpp. cpp is the C/C++ preprocessor (interprets macros, removes comments, inserts includes, resolves trigraphs). The -fpreprocessor option tells cpp to assume the input has already been preprocessed so it will only replace comment lines with blank lines. The -L 1 option tells xargs to launch one process for each line, indeed cpp can only process one file at the time...
This is sample output - yours may be different.

find . -name '*.java' | xargs -L 1 cpp -fpreprocessed | grep . | wc -l

What's this?

commandlinefu.com is the place to record those command-line gems that you return to again and again. That way others can gain from your CLI wisdom and you from theirs too. All commands can be commented on, discussed and voted up or down.

Get a list of the erroring cifs entries in fstab

It disturbs me when my logwatch report tells me a share or machine has disappeared, esp as mount isn't telling me what's gone. This command outputs to stderr the erroring cifs entries from fstab.

Which processes are listening on a specific port (e.g. port 80)

swap out "80" for your port of interest. Can use port number or named ports e.g. "http"

Clear your history saved into .bash_history file!

Note the space before the command; that prevents your history eliminating command from being recorded. ' history -c && rm -f ~/.bash_history' Both steps are needed. 'history -c' clears what you see in the history command. 'rm -f ~/.bash_history' deletes the history file in your home directory.

Echo the latest commands from commandlinefu on the console

A Quick variation to the latest commands list with the new-lines skipped. This is faster to read.

Email yourself a short note

I created this so I could send myself an email alert when a long-running job was finished, e.g., $ my_long_job.exe ; quickemail my_long_job.exe has finished

Project your desktop using xrandr

HDMI-1 is the interface in the example, which can be obtained just by typing xrandr and surfing through the output. There are a hell lot of configurations that can be done but I prefer auto because it works in most cases. $ Lifesaver

List all packages in Ubuntu/Debian that no package depends on

Create a mirror of a local folder, on a remote server

Create a exact mirror of the local folder "/root/files", on remote server 'remote_server' using SSH command (listening on port 22) (all files & folders on destination server/folder will be deleted)

Get your commandlinefu points (upvotes - downvotes)

This will calculate the your commandlinefu votes (upvotes - downvotes). Hopefully this will boost my commandlinefu points.

Check which files are opened by Firefox then sort by largest size.

Just refining last proposal for this check, showing awk power to make more complex math (instead /1024/1024, 2^20). We don't need declare variable before run lsof, because $(command) returns his output. Also, awk can perform filtering by regexp instead to call grep. I changed the 0.0000xxxx messy output, with a more readable form purging all fractional numbers and files less than 1 MB.

Stay in the loop…

Follow the Tweets.

Every new command is wrapped in a tweet and posted to Twitter. Following the stream is a great way of staying abreast of the latest commands. For the more discerning, there are Twitter accounts for commands that get a minimum of 3 and 10 votes - that way only the great commands get tweeted.
