Problem with script

[Paul Smith]

Dear All,

I am trying to run a script with the following command:

echo "~/scripts/teste.sh" | at 5:59PM

but nothing happens.

My script is:

---------------------------------------
#!/bin/bash

gxmessage -center \
          -buttons "Yes":1,"Of Course":2 \
          -geometry 290x80 \
          -title "Linux Journal Question" 'Does Shawn Powers ROCK?'

answer=$?

case "$answer" in
  1)
    gxmessage -center "You said 'YES'"
    ;;
  *)
    gxmessage -center "I agree, Of Course."
    ;;
esac
---------------------------------------

If I run

sh ~/scripts/teste.sh

the script works as expected.

Any ideas?

Thanks in advance,

Paul

Try putting some echo commands into the script, redirected to a file so 
that you can see if the script runs at all, and if so, how far it gets.

Thanks, Joe. I am going to try that, but the following log may help to
trace down the problem:

Also check at -l, or atq to see if it is scheduled to run later.

Thanks, Clifford. No, they are not scheduled to start later -- I have
just checked that with atq. Moreover, the log tells that the script is
run at the specified time.

Adding echo or print statements to a program or script for debugging is 
such an old technique that most people have either forgotten it or never 
learned it.

If you want, you can add -M to the at command to suppress all mail and 
get rid of that.

[Paul Smith]

Thanks, Joe. I put

echo xxx

in the second line of the script and nothing was printed.

The log mentions the creation of a new session, which is closed when
(apparently) the execution of the script finishes.

That's because there is no tilde expansion inside of quotes.

Lose the quotes and all will be well.

[Paul Smith]

Thanks, Ulf and Garry.

Ulf seems to be right, as the following

echo  "XAUTHORITY=/run/user/1000/gdm/Xauthority DISPLAY=:0 gxmessage
"hello"" | at 7:52PM -M

while

echo  "gxmessage "hello"" | at 7:52PM -M

does not.

Should I put

XAUTHORITY=/run/user/1000/gdm/Xauthority DISPLAY=:0

in the script? The syntax is correct?

gxmessage relays on an X11 display. You have none in a session started 
via atd.

Assuming, you are running gnome and your uid is 1000,

XAUTHORITY=/run/user/1000/gdm/Xauthority DISPLAY=:0 gxmessage ...

may work.

You're confusing this with cron. At preserves your environment. If he's 
still logging into his X11 session this should work.

Yes, agree, you are right.

Best regards

[Paul Smith]

Fixed now! I had to put the following line in the script:

export DISPLAY=:0
