hi

i am writing a script witch should output one line to the user in an editable field

if the user presses enter the characters in the field should be read back in a variable.

long time ago i used a external (ncurses like) programm which does exactly this but i cant remember it any more o:|

can something like this done native with bash?

thanks!

there was a missing character but this works great!

Code:

read -p 'prompt: ' -e -i 'text' var && echo $var

is there a parameter to enable "vi edit mode" only for this read?

there is a tool deploying "ncurses" .
It is called dialog and offers some widgets like Textbox, Progressbar, Date/Time selector and alike. It should already be installed.
List of widgets available:

Code:

  --buildlist    
  --calendar     
  --checklist    
  --dselect      
  --editbox      
  --form         
  --fselect      
  --gauge        
  --infobox      
  --inputbox     
  --inputmenu    
  --menu         
  --mixedform    
  --mixedgauge   
  --msgbox       
  --passwordbox  
  --passwordform 
  --pause        
  --prgbox       
  --programbox   
  --progressbox  
  --radiolist    
  --rangebox     
  --tailbox      
  --tailboxbg    
  --textbox      
  --timebox      
  --treeview     
  --yesno

If you want to script the same for DesktopEnvironments then use kdialog if on KDE.
zenity if it is GNOME

Via dbus the InterProcessCommunication tool one can even send commands to other Windows. Use qdbus for this. ( And dbusviewer to learn it.)
