I digested about 1/3 of a book on shell scripting and have been trying to add weather information to an openbox window manager.
The following works with the default shell in FreeBSD and NetBSD:
~/scripts/weather.sh
Code:
#!/bin/sh
curl -sk http://weather.noaa.gov/pub/data/observations/metar/decoded/KYKM.TXT | \
fold -w 78 -s
echo ""
read -p "<Enter to Close>" nothing
Which I call with the following openbox menu entry
Code:
xterm -g 78x16+150+38 -T "Yakima, WA Weather" -e ~/scripts/weather.sh
When I try the same script/menu entry in OpenBSD the xterm does not wait for "read" input and closes immediately.
Using
$ xterm -hold -e ~/scripts/test.sh I get the following:
Code:
YAKIMA AIR TERMINAL, WA, United States (KYKM) 46-34N 120-32W 324M

./test.sh[5]: read: -p: no coprocess
Ideally, I would like the scripts to be portable. Can someone give me a brief explanation and suggestions about how to script this for OpenBSD? Ultimately, I would like to pass the output into a dialog program like zenity or yad.
