  • Copy file to a Windows/Samba share without mounting it

    This commando copies the file (which must reside in the current directory) to //<server>/<share-name>/<subdirectory>/<file> through the CIFS protocol (Samba share or Windows Share). It doesn't require you to mount the filesystem first. --directory "<subdirectory>" may be omitted in order to copy the file the the root of the share. The "%password" part may also be omitted. If doing so, smbclient will ask for the password interactively. To copy a file from a Windows/Samba share, change "put" for "get". smbclient --user=user%password --directory "&lt;subdirectory&gt;" --command "get &lt;file&gt;" //&lt;server&gt;/&lt;share-name&gt; Show Sample Output

    smbclient --user=user%password --directory "<subdirectory>" --command "put <file>" //<server>/<share-name>

  • List wireless clients connected to an access point

    When the wireless card is in AP mode, list the users which are connected to the network. It uses the new nl80211 based CLI configuration utility for wireless devices. It can be used, for example, in a dd-wrt based router through a telnet session to obtain client information. Show Sample Output

  • Pushing changes to an empty git repository for the first time

    After cloning an empty repository on the client ("git clone" just after "git init", for instance), "git push" fails. In order to be able to push to this repository for the first time, you need to run the above command. It will link your local "master" branch to the "master" branch in the origin server, and push the changes. This is only necessary only for the first push; after that, you can use just the commands "git push" or "git pull" in order to do this operations. Show Sample Output

    git push --set-upstream origin master

  • Disconnect a wireless client on an atheros-based access point

    This command will disconnect the user whose mac was specified from the current list of clients from the wireless network when the network card is working in access point mode. Works on atheros-based access points which use the madwifi driver (not sure, but don't think it will work on access points which are not atheros-based, as it uses the atheros's iwpriv extensions). It will not prevent the user from reconnecting to the network, but may force the user to roam to another AP, with stronger signal. Show Sample Output

    iwpriv ath<x> kickmac <macaddress>

  • Compress and store the image of a disk over the network

    Create an image of "device" and send it to another machine through the network ("target" and "port" sets the ip and port the stream will be sent to), outputting a progress bar On the machine that will receive, compress and store the file, use: nc -l -p <port> | 7z a <filename> -si -m0=lzma2 -mx=9 -ms=on Optionally, add the -v4g switch at the end of the line in order to split the file every 4 gigabytes (or set another size: accepted suffixes are k, m and g). The file will be compressed using 7z format, lzma2 algorithm, with maximum compression level and solid file activated. The compression stage will be executed on the machine which will store the image. It was planned this way because the processor on that machine was faster, and being on a gigabit network, transfering the uncompressed image wasn't much of a problem.

Copy sparse files
This causes cp to detect and omit large blocks of nulls. Sparse files are useful for implying a lot of disk space without actually having to write it all out. http://en.wikipedia.org/wiki/Sparse_file You can use it in a pipe too: $ dd if=/dev/zero bs=1M count=5 |cp --sparse=always /dev/stdin SPARSE_FILE

Most Commonly Used Grep Options
This is very helpful to place in a shell startup file and will make grep use those options all the time. This example is nice as it won't show those warning messages, skips devices like fifos and pipes, and ignores case by default.

Which processes are listening on a specific port (e.g. port 80)
swap out "80" for your port of interest. Can use port number or named ports e.g. "http"
