  • Efficiently clear all Windows Event log entries from within a Cygwin terminal. Uses "cygstart" to launch a hidden "PowerShell" session passing a Powershell command to loop through and clear all Windows Event Log entries. Very useful for troubleshooting and debugging. The command should in theory elevate you session if needed. One liner is based on the PowerShell command: wevtutil el | foreach { wevtutil cl $_ }

    cygstart --hide -wa runas powershell -WindowStyle Hidden -Command '"&{wevtutil el | foreach{wevtutil cl $_}}"'

  • Outputs Windows Services service name and display name using "sc query", pipes the output to "awk" for processing, then "column" for formatting. List All Services: sc query state= all | awk '/SERVICE_NAME/{printf"%s:",$2;getline;gsub(/DISP.*:\ /,"");printf"%s\n",$0}' | column -ts\: List Started Services: sc query | awk '/SERVICE_NAME/{printf"%s:",$2;getline;gsub(/DISP.*:\ /,"");printf"%s\n",$0}' | column -ts\: List Stopped Services: sc query state= inactive| awk '/SERVICE_NAME/{printf"%s:",$2;getline;gsub(/DISP.*:\ /,"");printf"%s\n",$0}' | column -ts\: Show Sample Output

  • Using "wmic get * /value" within any Cygwin shell will return lots of Win/Dos newline junk ie "^M$" at the end of found value line, two lines ("$" Unix newline) above, and three below. This makes storing and or evaluating wmic queries as variables a pain. The method i suggest strips the mentioned junk, only returns the value after "OSArchitecture=", and includes only one Unix style newline. Other methods using sed|awk|cut can only handle the output of wmic cleanly when piped or using multiple sed statements. wmic OS get OSArchitecture /value | sed 's/\r//g;s/^M$//;/^$/d;s/.*=//' making wmic OS get OSArchitecture /value | grep -Eo '[^=]*$' a much cleaner and slightly less costly alternative.

  • Pass the files path to finfo(), can be unix path, dos path, relative or absolute. The file is converted into an absolute nix path, then checked to see if it is in-fact a regular/existing file. Then converted into an absolute windows path and sent to "wmic". Then magic, you have windows file details right in the terminal. Uses: cygwin, cygpath, sed, and awk. Needs Windows WMI "wmic.exe" to be operational. The output is corrected for easy... finfo notepad.exe finfo "C:\windows\system32\notepad.exe" finfo /cygdrive/c/Windows/System32/notepad.exe finfo "/cygdrive/c/Program Files/notepad.exe" finfo ../notepad.exe Show Sample Output

    finfo() { [[ -f "$(cygpath "$@")" ]] || { echo "bad-file";return 1;}; echo "$(wmic datafile where name=\""$(echo "$(cygpath -wa "$@")"|sed 's/\\/\\\\/g')"\" get /value)"|sed 's/\r//g;s/^M$//;/^$/d'|awk -F"=" '{print $1"=""\033[1m"$2"\033[0m"}';}

  • Download latest NVIDIA Geforce x64 Windows7-8 driver from Nvidia's website. Pulls the latest download version (which includes beta). This is the "English" version. The following command includes a 'sed' line to replace "english" with "international" if needed. You can also replace the starting subdomain with "eu." "uk." and others. Enjoy this one liner! 1 character under the max :) wget "us.download.nvidia.com$(wget -qO- "$(wget -qO- "nvidia.com/Download/processFind.aspx?psid=95&pfid=695&osid=19&lid=1&lang=en-us" | awk '/driverResults.aspx/ {print $4}' | cut -d "'" -f2 | head -n 1)" | awk '/url=/ {print $2}' | sed -e "s/english/international/" | cut -d '=' -f3 | cut -d '&' -f1)" Show Sample Output

  • Usage: google "[search string]" Example: google "something im searching for" This will launch firefox and execute a google search in a new tab with the provided search string. You must provide the path to your Firefox binary if using cygwin to $ff or create an alias like follows: alias firefox='/cygdrive/c/Program Files (x86)/Mozilla Firefox/firefox.exe' Most Linux flavors with Firefox installed will use just ff="firefox" and even OSX.

    google() { gg="https://www.google.com/search?q="; ff="firefox"; if [[ $1 ]]; then "$ff" -new-tab "$gg"$(echo ${1//[^a-zA-Z0-9]/+}); else echo 'Usage: google "[seach term]"'; fi }

  • Quickly remove the conflicting line (key) from current users known_hosts file when there is an SSH host conflict. Very nice when you get tired of writing out full commands. Ideally you would place this into your .bash_profile Usage: rhost [n] Example: rhost 33 (removes line 33 from ~/.ssh/known_hosts) Function assumes the $HOME exists, you could alternatively use "~/.ssh/known_hosts" Mac OSX likes a space for sed -i "$1" d


    -1
    rhost() { if [[ $1 =~ ^[0-9]+$ ]]; then sed -i "$1"d ${HOME}/.ssh/known_hosts; else echo "rhost [n]"; fi }

  • This alternative either opens the current working directory by just issuing the open function in the commandline. Or you can specify what directory you would like to open. Example: open /cygdrive/c/Windows Usage: open [path] When no option is specified it will open the current working directory


    1
    open(){ if [[ -n "$1" ]];then explorer /e, $(cygpath -mal "$PWD/$1");else explorer /e, $(cygpath -mal "$PWD");fi }

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.

Skip over .svn directories when using the
Put the positive clauses after the '-o' option.

Recursively unrar into dir containing archive
From the cwd, recursively find all rar files, extracting each rar into the directory where it was found, rather than cwd. A nice time saver if you've used wget or similar to mirror something, where each sub dir contains an rar archive. Its likely this can be tuned to work with multi-part archives where all parts use ambiguous .rar extensions but I didn't test this. Perhaps unrar would handle this gracefully anyway?

Run remote web page, but don't save the results
I have a remote php file that I want to run once an hour. I set up cron to run this wget. I don't really care about what's in the file though, I don't want to save the results, so I run the -O and send it to /dev/null

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

Show one line summaries of all DEB packages installed on Ubuntu based on pattern search
I sometimes want to know what packages are installed on my Ubuntu system. I still haven't figured out how to use aptitude effectively, so this is the next best thing. This allows finding by name. The grep '^ii' limits the display to only installed packages. If this is not specified, then it includes listing of non-installed packages as well.

Facebook Email Scraper
(Apparently it is too long so I put it in sample output, I hope that is OK.) Run the long command (or put it in your .bashrc) in sample output then run: $ fbemailscraper YourFBEmail Password Voila! Your contacts' emails will appear. Facebook seems to have gotten rid of the picture encoding of emails and replaced it with a text based version making it easy to scrape! Needs curl to run and it was made pretty quickly so there might be bugs.

use wget to check if a remote file exists
put your link [url] to check if exist the remote file

clone an USB stick using dd + see its process
The following command will clone usb stick inside /dev/sdc to /dev/sdd Double check you got the correct usb sticks (origional-clone)with fdisk -l.

Get the total length of all videos in the current dir in H:m:s
You're behind on your TV catch-up, but how far behind? This command tries to open mplayer against all files in the current dir. If it's a video file it will contain ID_LENGTH, which is summed and output in hours, minutes and seconds. Someone better at awk could probably reduce this down a lot.
