Answer / satchi
"shift" is useful when you need to access positional
parameters more than 9.
EX- execute a script to display 11th position parameter.
#./test.sh 1st 2nd 3rd 4th 5th 6th 7th 8th 9th 10th 11th
12th
shell scripts limits the access of arguments up to 9.to
over come this calculate the position of argument you want
to access and use shift to pull inside 9th countdown.
ex:
withen the script write "shift 2" before "echo $9"to
display 11th parameter.
withen the script write "shift 3" before "echo $9"to
display 12th parameter.
