There are plenty of examples how to copy the contents of a file from command line with the help of xclip or xsel. What I am looking for is to copy a file from the command line and paste into the file explorer. So I will use a command to copy a file, not only the contents, and use Ctrlv to paste it in UI.updatedxclip-copyfile and xclip-pastefile work close to what I expect, but when I run xclip-copyfile, I can only paste with xclip-pastefile command, not GUI paste.
Copy file from commandline, paste into Gnome window or vice-versa
copy paste
I use Nautilus, in Ubuntu, as my File Browser, so I can't speak for  any other browser.The way in which Nautilus handles pasting a file via Ctrl-v is quite local to Nautilus, ie. Nautilus only recognizes Ctrl-v as paste a file in response to a copy file command which was issued while in nautilus itself.  This means that you can't use Ctrl-v to paste a file whose path you copied in another application.    However, if it suits you, Ctrl+Shift+v can be bound to a script which runs under nautilus-scripts-manager. With this script, you can do pretty much whatever you like.   nautilus-scripts-manager gives you access to some fundamental information about the current directory and which files/directories are selected.  One thing I particularly like about nautilus-scripts is that it adds its scripts to the File menu item (as well as to the context-menu). This allows you to set a key-binding which is local to Nautilus 3 or Nautilus 2.      Here is a rough example, using your already mentioned xclip-pastefiles example. Note, that as it stands now, it requires that you set up the xclip-copyfiles before running this Ctrl-Shift-v paste script.Once you have run the setup xclip-copyfiles, you need only navigate to a Nautilus window, and selcet the  target directory (or a file in that directory) and press your script's keybinding: Ctrl-Shift-v #!/bin/bash   # Note: `leafpad' is a simple text editor which doubles as a quick-and-easy testing messsage-boxdir=$(echo $NAUTILUS_SCRIPT_SELECTED_FILE_PATHS |sed -n 1p)if [[ -n $dir ]] ;then    # target dir from `Nautilus Scripts' (1st priority)        if [[ -e $dir ]] ;then       [[ -d $dir ]] || dir=${dir%/*}        [[ -d $dir ]] || dir=    fielse  # target dir from $1 (2nd priority)    dir=$1    if [[ -e $dir ]] ;then       [[ -d $dir ]] || dir=${dir%/*}        [[ -d $dir ]] || dir=    fifiif [[ -z $dir ]] ;then    # target dir from clipboard (if not in $NAUTILUS_SCRIPT.. or  $1)   dir=$(xclip -o -sel c)   if [[ -e $dir ]] ;then      [[ -d $dir ]] || dir=${dir%/*}       [[ -d $dir ]] || dir=    else      dir=   fifi[[ -d $dir ]] || { echo $(basename $0): target directory not found in clipboard |leafpad; exit 1; } { cd   $dir  echo Current  Directory:   echo   $dir  echo =======  echo  xclip-pastefile # run your command  (`echo' is for testing)} 2>&1 |leafpad
