I want to learn shell-scripting. I want to create simple tool to show file content with edit option but I can't get value from
dialog --editbox
#!/bin/bash
BACKTITLE="Some backtitle"
FILENAME="filename.txt"
touch $FILENAME
INPUT=/tmp/menu.sh.$$
ret=0
while [ $ret -eq 0 ]
do
dialog --title "Menu" \
--backtitle "$BACKTITLE" \
--menu "Wybierz" 10 60 3 \
1 "Pokaz menu" \
2 "Edytuj" \
2>"${INPUT}"
ret=$?
option=$(<"${INPUT}")
if [ $ret -eq 0 ]
then
if [ $option -eq 1 ]
then
dialog --title "File content" \
--backtitle "$BACKTITLE" \
--textbox $FILENAME 10 60
elif [ $option -eq 2 ]
then
dialog --title "Edit file content" \
--backtitle "$BACKTITLE" \
--editbox $FILENAME 10 60
editboxret=$?
echo $editboxret
ret=0
fi
fi
done
Per the manpage (man dialog
), the output is written to stderr.
Using the suggestion in http://stackoverflow.com/a/6317938/5528982, you can use
{ newcontents=$(dialog --title "Edit file content" -- backtitle "$BACKTITLE" --editbox $FILENAME 10 60 2>&1 1>&$out); } {out}>&1
