After something is copied to clipboard (using ctrl+c) I want a script (bash, python or any other language) to automatically detect that new entry is added to clipboard, change it's content and put it back to clipboard so when I paste it I get the modified text. The script should constantly run in background and monitor the clipboard for changes.

The following script describes the modification that is needed :

#!/bin/bash

# title: copy_without_linebreaks
# author: Glutanimate (github.com/glutanimate)
# license: MIT license

# Parses currently selected text and removes 
# newlines that aren't preceded by a full stop

SelectedText="$(xsel)"

ModifiedText="$(echo "$SelectedText" | \
    sed 's/\.$/.|/g' | sed 's/^\s*$/|/g' | tr '\n' ' ' | tr '|' '\n')"

#   - first sed command: replace end-of-line full stops with '|' delimiter and keep original periods.
#   - second sed command: replace empty lines with same delimiter (e.g.
#     to separate text headings from text)
#   - subsequent tr commands: remove existing newlines; replace delimiter with
#     newlines
# This is less than elegant but it works.

echo "$ModifiedText" | xsel -bi

I do not want to use shortcut key binding to run the script.

When I use putty from a Windows box to linux (without X11 installed), is there an alternative to xsel or xclip? xclip/xsel need X11. I would like to pipe the complete shell command output to the clipboard which I then paste on the Windows box to an application. I would like not to have to install all the X11 dependencies xsel and xclip need on those linux servers. Is this possible? Dan

I am trying to copy my public key on a VPS.

After I connect I run the following

xclip -sel clip < ~/.ssh/id_rsa.pub

Xclip gives me a can't open display error.

Right now I manually open the file and copy the key. There has to be a better, faster way to do this.

I'm trying to make a submenu entry on a .desktop application file that launches a youtube address with mpv. The youtube url is copied from the clipboard. Inside gnome-terminal this works fine:

xclip -o | xargs mpv

But if I make a .desktop action like this:

[Desktop Action mpv]
Name=mpv clipboard
Comment=Play the url on the clipboard with mpv
Exec=xclip -o | xargs mpv

It doesn't work. I have tried putting gnome-terminal -x before it, but it still doesn't work. How can it be done?

I am trying to copy from the terminal with xclip and paste it into the unity desktop environment into gedit text editor. I can copy and paste with xclip in terminal:

$ cat line-size.c | xclip
xclip -o > input5.txt
cat input5.txt
#include <stdio.h>
...

However, when I press control + v to paste into gedit, it only pastes the actual last thing I copied within unity desktop, such as something from firefox browser.

How can I paste in gui applications something I copied from terminal?
