  • 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

    sc query state= all | awk '/SERVICE_NAME/{printf"%s:",$2;getline;gsub(/DISP.*:\ /,"");printf"%s\n",$0}' | column -ts\:

  • 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. Show Sample Output

    wmic OS get OSArchitecture /value | grep -Eo '[^=]*$'

  • 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 "$(wget -qO- "$(wget -qO- "" | 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

    wget "$(wget -qO- "$(wget -qO- ""|awk '/driverResults.aspx/ {print $4}'|cut -d "'" -f2|head -n 1)"|awk '/url=/ {print $2}'|cut -d '=' -f3|cut -d '&' -f1)"

  • 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=""; 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

    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

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

What's this? 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.

defragment files
Thanks to flatcap for optimizing this command. This command takes advantage of the ext4 filesystem's resistance to fragmentation. By using this command, files that were previously fragmented will be copied / deleted / pasted essentially giving the filesystem another chance at saving the file contiguously. ( unlike FAT / NTFS, the *nix filesystem always try to save a file without fragmenting it ) My command only effects the home directory and only those files with your R/W (read / write ) permissions. There are two issues with this command: 1. it really won't help, it works, but linux doesn't suffer much (if any ) fragmentation and even fragmented files have fast I/O 2. it doesn't discriminate between fragmented and non-fragmented files, so a large ~/ directory with no fragments will take almost as long as an equally sized fragmented ~/ directory The benefits i managed to work into the command: 1. it only defragments files under 16mb, because a large file with fragments isn't as noticeable as a small file that's fragmented, and copy/ delete/ paste of large files would take too long 2. it gives a nice countdown in the terminal so you know how far how much progress is being made and just like other defragmenters you can stop at any time ( use ctrl+c ) 3. fast! i can defrag my ~/ directory in 11 seconds thanks to the ramdrive powering the command's temporary storage bottom line: 1. its only an experiment, safe ( i've used it several times for testing ), but probably not very effective ( unless you somehow have a fragmentation problem on linux ). might be a placebo for recent windows converts looking for a defrag utility on linux and won't accept no for an answer 2. it's my first commandlinefu command

Updated top ten memory utilizing processes (child/instance aggregation) now with percentages of total RAM
Prints the top 10 memory consuming processes (with children and instances aggregated) sorted by total RSS and calculates the percentage of total RAM each uses. Please note that since RSS can include shared libraries it is possible for the percentages to add up to more that the total amount of RAM, but this still gives you a pretty good idea. Also note that this does not work with the mawk version of awk, but it works fine with GNU Awk which is on most Linux systems. It also does not work on OS X.
