I need some help for a Linux exercise
Howdy,
I’m doing some exercises for my Linux scripting class in preparation for a test and was doing well until I hit the last exercise which currently has me mind boggled.
Any help would be greatly appreciated.
Ok, I need to insert the second script into the first one so that when trying to type d:3 for deleting the 3rd choice from the geeko file, I should be prompted with this: type y(es) or n(o)
So basically the second code has to be inserted into first one but so far I’ve had no luck.
Here is the first script:
#!/bin/bash
#finalize2.sh
tinum=`cat /var/spool/mail/geeko | grep '#' | wc -l`
if test $tinum -gt 10
then
echo -e "Welcome to the Request Tracker.\nThere are $tinum open requests. You have to do something!\a"
else
echo -e "Welcome to the Request Tracker.\nThere are $tinum open requests:\n"
fi
input='l'
until test $input = "quit"
do
reqnr=1
while read line
do
if echo $line | grep '#' > /dev/null
then
lines[$reqnr]="$reqnr|$line"
((reqnr++))
fi
done < /var/spool/mail/geeko
com=`echo $input | cut -d ':' -f 1`
req=`echo $input | cut -d ':' -f 2`
case $com in
'i') echo -e `echo ${lines[$req]} | cut -d '|' --output-delimiter='\n' -f '3 4 5 6'` ;;
'l') for ((i=1;i<=${#lines[@]};i++))
do
echo -e ${lines[$i]} | cut -d '|' --output-delimiter=', ' -f '1 3 4 5'
done
;;
'd') rm /var/spool/mail/geeko
for ((i=1;i<=${#lines[@]};i++))
do
if test $i -ne $req
then
echo ${lines[$i]} | cut -d '|' --output-delimiter='|' -f '2 3 4 5 6' >> /var/spool/mail/geeko
else
echo "Request $req deleted."
fi
done
;;
*) echo "Unknown Command"
esac
unset lines
read input
done
And the second:
#!/bin/bash
#Prompt the user to answer with "yes" or "no"
#The question itselfis supplied as an argument
#"When calling the function, for example?"
while true
do
echo "$*"
echo "Please answer by entering (y)es or (n)o:"
read ANSWER
case "$ANSWER" in
[yY] | [yY][eE][sS] )
return 0
;;
[nN] | [nN][oO] )
return 1
;;
* )
echo "I cannot undersand you over there."
;;
esac
done
