Clean upgrade of Ubuntu

sudo sh -c "apt-get update;apt-get dist-upgrade;apt-get autoremove;apt-get autoclean"

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.

archive all files containing local changes (svn)

This works more reliable for me ("cut -c 8-" had one more space, so it did not work)

copy from host1 to host2, through your host

This is a 'nocd' alternative :)

Assign function keys to your frequent commands

This is a common use of bind. Hitting any key after will output the key's character sequence. This makes possible using it into a bind command. So pressing ctrl+v and then F2 will output "^[[12~", once binded every time you'll press the function key F2 it will execute your command. Added the \n to make it execute it as well.

Using vim to save and run your python script.

This will save and execute your python script every time your press the F5 function key. It can also be added to your .vimrc: autocmd BufRead *.py nmap :w^M:!python % NOTE: the ^M is not just caret-M, it can be created by type: ctrl-v ctrl-m

Remove a file whose name begins with a dash ( - ) character

Using the redundant ./ directory information prevents the dash from occurring at the beginning of the filename, and being interpreted as an option of the rm command. Also works using: $ rm -- -filename

list files recursively by size

Convert CSV to JSON

Replace 'csv_file.csv' with your filename.

Draw kernel module dependancy graph.

parse "lsmod" output to "dot" format and pass it to "display". Without perl!

Advanced python tracing

Trace python statement execution and syscalls invoked during that simultaneously

Get a free shell account on a community server

Bash process substitution which curls the website 'hashbang.sh' and executes the shell script embedded in the page. This is obviously not the most secure way to run something like this, and we will scold you if you try. The smarter way would be: Download locally over SSL > curl https://hashbang.sh >> hashbang.sh Verify integrty with GPG (If available) > gpg --recv-keys 0xD2C4C74D8FAA96F5 > gpg --verify hashbang.sh Inspect source code > less hashbang.sh Run > chmod +x hashbang.sh > ./hashbang.sh
