I want to use command notify-send and display text from a file as a notification so that I can only edit that file to change command or forward contents from outputs of other programs to notify-send.
I tried :
notify-send -u critical -t 3000 < ~/ved
cat ved | notify-send -u critical -t 3000
It says : No summary specified.
What should I do about this summary?
http://www.commandlinefu.com/commands/view/4460/pipe-output-to-notify-send
says
echo 'information overlord' | while read OUTPUT; do notify-send "$OUTPUT"; done
git ls-remote "https://bitbucket.org/$username/$reponame.git" 2>&1 1>/dev/null | while read OUTPUT; do notify-send "error" "$OUTPUT" -i gtk-error; done

~/.bash_aliases: function notify { while read input; do notify-send "message" "$input"; done; }.
Im not sure what you want to do or what kind of file you want to display but man notify-send says
notify-send [OPTIONS] <summary> [body]
Summary being a title, so for example, the basename of your file.
So what you can do is
notify-send -u critical -t 3000 "$(basename ~/ved)" "$(cat ~/ved)"
But be aware that notify-send won't print long text file, it's not its job.
Also, I don't know for you or everyone else, but the -t option never worked for me, time being always 10s. I've read it was a bug a long time ago and it's still not working in 12.04.
Try this:
notify-send -u critical -t 3000 "$(cat ~/ved)"
