To allow them to continue after hitting any key, I usually create a function (I usually call it readOne, after the function I stole the idea from
 ):Code:
readOne () {
tput smso
echo "Press any key to return \c"
tput rmso
oldstty=`stty -g`
stty -icanon -echo min 1 time 0
dd bs=1 count=1 >/dev/null 2>&1
stty "$oldstty"
echo
}
blah blah ... readOne blah blah exit 0 HTH |

Very interesting. I've never seen a way to read a single character from a shell script before. But I want to be able to actually catch the character that is typed. So I changed the dd statement to:
result=`dd bs=1 count=1 2>/dev/null` which seems to be working. Very cool trick! |

Hi,
Well I was trying to see what exactly the script Livinfree posted is doing. I couldnt understand. Using man I could get that tput smso and rmso is for getting standout mode seq started and end it. dd bs sets the blcok size to 1.But why I didnt undertand. Is it because the requirement is that only ONE keystroke is required. however I couldnt understand how the rest of these work when put together. Could anyone pls explain. Thanks. |
