how to catch the return value of dialog without temp file ?

doublehp · 05-20-2005, 08:36 PM

my script is using at the moment:

Code:

r=`${DIAG} --title "Eapp editor" --fselect "" 50 100 2>&1`

which was very fine when DIAG points to Xdialog, but after a thought, it can not work as fine with dialog(ncurses) ...

Code:

${DIAG} --title "Eapp editor" --fselect "" 50 100 2>$r

is rejected by
GNU bash, version 3.00.16(1)-release (i686-pc-linux-gnu)

it complains about some ambiguous redirection ...

I am looking for a workaround NOT using any temporary file.

Any idea ?
