Commands tagged share (6)

  • If you enable multiuser, then you can permit others to share your screen session. The following conditions apply: 1. screen must be suid root; 2. "multiuser on" must be configured in ~/.screenrc; 3. control the others user(s) access with "aclchg": # ----- from ~/.screenrc-users ----- aclchg someuser +rx "#?" #enable r/o access to "someuser" aclchg someuser -x "#,at,aclchg,acladd,acldel,quit" # don't allow these aclchg otheruser +rwx "#?" # enable r/w access to "otheruser" aclchg otheruser -x "#,at,aclchg,acladd,acldel,quit" # don't allow them to use these commands # ----- After doing this (once), you start your session with: $ screen Then, the other user can join your terminal session(s) with youruserid: $ screen -r youruserid/ Note: the trailing "/" is required. Multiple users can share the same screen simultaneously, each with independent access controlled precisely with "aclchg" in the ~/.screenrc file. I use the following setup: # ~/.screenrc-base # default screenrc on any host source $HOME/.screenrc-base source $HOME/.screenrc-$HOST source $HOME/.screenrc-users # ----- Then, the base configurations are in ~/.screenrc-base; the host-specific configurations are in ~/.screenrc-$HOST, and the user configurations are in ~/.screenrc-users. The host-specific .screenrc file might contain some host-specific screen commands; e.g.: # ~/.screen-myhost # ----- screen -t 'anywhere' /bin/tcsh screen -t 'anywhere1' /bin/tcsh # ---- The .screenrc-base contains: # ~/.screenrc-base ## I find typing ^a (Control-a) awkward. So I set the escape key to CTRL-j instead of a. escape ^Jj termcapinfo xterm* [email protected]:[email protected]: autodetach on zombie kr verbose on multiuser on

  • is a code/text sharing site like pastebin, but it is easy to post stuff from the command line. How it works: :w !command In vim, w writes the current tab to a file when a filename is given afterwards, but if !command is given, the output is piped to the stdin of command. curl -F "sprunge=<-" curl is an HTTP client. The -F option does an HTTP post to the given address. The data in the quotes is passed in the post. The "sprunge=" part sets up a fieldname - the part that follows is what is associated with the name. The "<" tells curl to send data from the file descriptor that follows it. The "-" in bash is a file descriptor that points to stdin instead of an actual file; in this case, stdin is being piped in from vim. After we send the HTTP post to, it will give back a url that points to the data you just sent. | xclip xclip is a utility that lets you put stuff in your clipboard or selection buffer. This part uses a bash pipe ( | ) to redirect the stdout of the previous command to the stdin of the next command. So, we're capturing the URL that curl gave us and putting it into the selection buffer, ready to paste into IRC or a forum. Notes: Of course, for this to work, you must have curl (which comes by default on most distroes), and xclip installed. When you share the url, you can append "?lang" to highlight and have line numbers. Check out for line numbers and for highlighting. If you prefer to use ctrl-v (paste from clipboard) instead of middle-click (paste from selection buffer), look up options on xclip - you can do that. Show Sample Output

    :w !curl -F "sprunge=<-" | xclip

  • Here's how to serve a directory in one line of Ruby. Handy for sharing files at a conference, for example.

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.

Share Your Commands

Check These Out

Find the package that installed a command

execute your commands and avoid history records
Sometimes you don't want to leave history, because of passwords use or somethink like. I think it help.

Get the Volume labels all bitlocker volumes had before being encrypted
Get information of volume labels of bitlocker volumes, even if they are encrypted and locked (no access to filesystem, no password provided). Note that the volume labels can have spaces, but only if you name then before encryption. Renaming a bitlocker partition after being encrypted does not have the same effect as doing it before.

Submit command & rewrite orginal command
Similar to entering a command, but will not erase the command from the command line. Basically a shortcut from entering command, then pushing the up arrow key.

print java packages by using unix tree and sed
if you need a quick way of printing out all the packages that contain classes this command will print the directory structure and replace '/' with '.' It will also ignore CVS directories (we use CVS here)

Show the UUID of a filesystem or partition
Shows the UUID of a filesystem or partition that can be used in kernel root options and in fstab. Run it without the -u option to generate more information. eg: ~/ sudo vol_id /dev/sda2 ID_FS_USAGE=other ID_FS_TYPE=swap ID_FS_VERSION=2 ID_FS_UUID=27fca13d-97b7-4d28-882c-6d03353f0a82 ID_FS_UUID_ENC=27fca13d-97b7-4d28-882c-6d03353f0a82 ID_FS_LABEL= ID_FS_LABEL_ENC=

View the newest xkcd comic.
This function displays the latest comic from One of the best things about xkcd is the title text when you hover over the comic, so this function also displays that after you close the comic. To get a random xkcd comic, I also use the following: $xkcdrandom(){ wget -qO-|tee >(feh $(grep -Po '(?


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"

Diff files on two remote hosts.
