Problem in coding

[ancris00]

Hi all,
I have an script that send a photo through Telegram:

Code: Select all

#!/bin/bash
tgpath=/home/pi/tg
cd ${tgpath}
(sleep 3; echo "send_photo $1 $2"; echo "safe_quit") | ${tgpath}/bin/telegram-cli -k tg-server.pub -W

Then I run the following command:

Code: Select all

/home/pi/tg_photo.sh <firstname>_<lastname> /home/pi/photo.jpg

I want to just run the command /home/pi/tg_photo.sh

without writing: <firstname>_<lastname> /home/pi/photo.jpg

So I modified the script:

Code: Select all

#!/bin/bash
tgpath=/home/pi/tg
cd ${tgpath}
(sleep 3; echo "send_photo <firstname>_<lastname> /home/pi/photo.jpg"; echo "safe_quit") | ${tgpath}/bin/telegram-cli -k tg-server.pub -W

but I does not work

any help?
Thanks

What is the sleep 3 for?

What is the sleep 3 for?

I was wondering that. I'd expect something similar between or after the two echo commands, not before them.

Hi,
I don't know for what is the sleep 3
but apart from that?
