Why remember? Generate!

Up to 48 chars, works on any unix-like system (NB: BSD use md5 instead of md5sum)

cat /var/log/auth.log | grep -i "pam_unix(sshd:auth): authentication failure;" | cut -d' ' -f14,15 | cut -d= -f2 | sort | uniq
2011-10-25 04:58:09
User: JohnQUnknown
Functions: cat cut grep sort

This command shows a sorted list of the IP addresses from which there have been authentication errors via SSH (possible script kiddies trying to gain access to your server), it eliminates duplicates so it's easier to read, but you can remove the "uniq" command at the end, or even do a "uniq -c" to have a count of how many times each IP address shows in the log (the path to the log may vary from system to system)

User: frntn
Functions: alias cut find head sort vim wc

Enhancement for the 'busy' command originally posted by busybee : less chars, no escape issue, and most important it exclude small files ( opening a 5 lines file isn't that persuasive I think ;) )

This makes an alias for a command named 'busy'. The 'busy' command opens a random file in /usr/include to a random line with vim.

User: Neo23x0
Functions: cut echo md5sum sed

Command makes use of the Malware Hash Registry (http://www.team-cymru.org/Services/MHR/).

It parses the current directory and subdirectories and calculates the md5 hash of the files, then prints the name and sends the hash to the MHR for a lookup in their database.

The 3rd value in the result is the detection percentage across a mix of AV packages.

Decrypt MD5 , replace 1cb251ec0d568de6a929b520c4aed8d1 with the MD5 string you want to decrypt

Functions: cut find

An alias cannot be executed as command in a find -exec line. This form will trick the command line and let you do the job.

In case sed and awk are not available you may use this to remove the last character from a string with "rev" and "cut".

This is just a "cut" addicted variant of the previous unixmonkey24730 command...

fn=$(find . -type f -printf "%T@\t%p\n"|sort -n|tail -1|cut -f2); echo $(date -r "$fn") "$fn"

User: titus
Functions: cut tar tr xargs

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

function expand_url() { curl -sI $1 | grep Location: | cut -d " " -f 2 | tr -d "\n" | pbcopy }

Expand a URL, aka do a head request, and get the URL. Copy this value to clipboard.

allVideos() { find ./ -type f -print0 | xargs -0 file -iNf - | grep ": video/" | cut -d: -f1; }
2011-08-19 11:58:59
User: totti
Functions: cut file find grep xargs

Videos are found using their MIME type. Thus no need to for an extension for the video file.

This is a efficent version of "jnash" cmd (4086). Thanks for jnash. This cmd will only show video files while his cmd show files having "video" anywhere in path.

Grabs the Apache config file (yielded from httpd) and returns the path specified as DocumentRoot.

git branch | cut -c3- | grep -v "^master$" | while read line; do git branch -d $line; done | grep 'Deleted branch' | awk '{print $3;}' | while read line; do git push <target_remote> :$line; done
2011-08-13 16:58:34
User: gocoogs
Functions: awk cut grep read

attempts to delete all local branches. git will fail on any branches not fully merged into local master, so don't worry about losing work. git will return the names of any successfully deleted branches. Find those in the output with grep, then push null repositories to the corresponding names to your target remote.


- your local and remote branches are identically named, and there's nothing extra in the remote branch that you still want

- EDIT: you want to keep your local master branch
