Save disk space by removing help and documentation files

Never read the documentation? No, then why have that ~ 20 MB sit there and take up space? This command preserves directory structure wile removing all of those unnecessary help and documentation files. Works on Ubuntu, Debian, and most related systems. Gives a lot of directory errors, I'll fix those later.

Short alias for sudo

This is way faster than typing 'sudo'. And AFAIK - there is no decent command for letter 's'.

Look at logs startring at EOF

In cases when the user is following a log file that rotates then it is advisable to use the -F option as it keeps following the log even when it is recreated, renamed, or removed as part of log rotation. To interrupt tail while it is monitoring, break-in with Ctrl+C.

Add a line for your username in the /etc/sudoers file, allowing you to sudo in Fedora

I am new to linux, and I was trying to figure out why I could not sudo with my username in Fedora 10. This command, when run as root, will add a line to the sudoers file allowing the loginname supplied to sudo. The above line will require a password when you sudo, if you wish to sudo without password, use: echo 'loginname ALL=(ALL) NOPASSWD:ALL' >> /etc/sudoers instead. you have to run this command as su, and this is just an easier way of using visudo, just adds it right from the terminal.

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 AWS temporary credentials ready to export based on a MFA virtual appliance

You might want to secure your AWS operations requiring to use a MFA token. But then to use API or tools, you need to pass credentials generated with a MFA token. This commands asks you for the MFA code and retrieves these credentials using AWS Cli. To print the exports, you can use: `awk '{ print "export AWS_ACCESS_KEY_ID=\"" $1 "\"\n" "export AWS_SECRET_ACCESS_KEY=\"" $2 "\"\n" "export AWS_SESSION_TOKEN=\"" $3 "\"" }'` You must adapt the command line to include: * $MFA_IDis ARN of the virtual MFA or serial number of the physical one * TTL for the credentials

Run a command, store the output in a pastebin on the internet and place the URL on the xclipboard

The URL can then be pasted with a middle click. This is probably useful when trying to explain problems over instant messaging when you don't have some sort of shared desktop.

Lines per second in a log file

Another way of counting the line output of tail over 10s not requiring pv. Cut to have the average per second rate : tail -n0 -f access.log>/tmp/tmp.log & sleep 10; kill $! ; wc -l /tmp/tmp.log | cut -c-2 You can also enclose it in a loop and send stderr to /dev/null : while true; do tail -n0 -f access.log>/tmp/tmp.log & sleep 2; kill $! ; wc -l /tmp/tmp.log | cut -c-2; done 2>/dev/null

Create colorized html file from Vim or Vimdiff

While editing a source file in vim, or using vimdiff to compare two or more files, the ':TOhtml' command can be used to export each buffer as an html file, including syntax highlighting and vimdiff colorization. If you are in insert mode in vim, you will have to type :TOhtml This will open a new buffer filled with html, which you can then save.

Fix "broken" ID3 tags in the current directory and subdirectories

Some MP3s come with tags that don't work with all players. Also, some good tag editors like, EasyTAG output tags that don't work with all players. For example, EasyTAG saves the genre as a numeric field, which is not used correctly in Sansa MP3 players. This command corrects the ID3 tags in MP3 files using mid3iconv, which comes with mutagen. To install Mutagen on Fedora use "yum install python-mutagen"

Suppress output of loud commands you don't want to hear from

shuffle lines via perl

Same, without modules... Probably smarter option: just use the shuf command or even sort -R.
