Hello,
From a source of mine:
local / typeset = variables declared with local are in scope for the
current shell. The typeset built-in command can also be used to declare
variables.
export = global variables, called also environment variables, are
set for the currently running shell and any process spawned from that
shell.
By *the local boat* should be:
local mypath="/home"
local myfile="file.txt"
local line=""
local arg
local y=0
y=0
arg[$y]="hello"
y=$y+1
arg[$y]="dan"
y=$y+1
arg[$y]="nuggetsman"
#debug
echo ${arg[0]}
echo ${arg[1]}
echo ${arg[2]}
y=0
cat $mypath'/'$myfile |
while read -r line
do
#debug
echo "y="$y
echo "line="$line
arg[$y]=$line
#debug
echo "arg[y]="${arg[$y]}
y=$y+1
done
#debug
echo ${arg[0]}
echo ${arg[1]}
echo ${arg[2]}
exit 1
By *the export boat* should be:
local mypath="/home"
local myfile="file.txt"
export arg1="hello"
export arg2="dan"
export arg3="nuggetsman"
export line=""
export y=0
#debug
echo $arg1
echo $arg2
echo $arg3
y=0
cat $mypath'/'$myfile |
while read -r line
do
#debug
echo "y="$y
echo "line="$line
case $y in
0 )
export arg1=$line
#debug
echo "arg1="$arg1
;;
1 )
export arg2=$line
#debug
echo "arg2="$arg2
;;
2 )
export arg3=$line
#debug
echo "arg3="$arg3
;;
esac
y=$y+1
done
#debug
echo $arg1
echo $arg2
echo $arg3
exit 1
The final result is always:
hello
dan
nuggetsman
Can't solve the quiz, any hint?
