I have this shell script :

Code:

Usage: $0 {all | opt1 | opt2 | opt3 | ... | opt9}"

case $1 inall )expression 1  //very long
expression 2   //very long
expression 3   //very long
expression 4   //very long
....
expression 9 ;;
opt1 )expression 1 ;;   //very long
opt2 )expression 2 ;;   //very long
.....
opt9 )expression 9 ;;

In my situation, every expression is very long and have many command...

How can I reduce typing in the option 'all' so it work with all the option from 1->9->n

Put the code in functions:

Code:

exp1() { : whatever; }
exp2() { : whatever; }
...
exp9() { : whatever; }

case $1 in
   all) exp1; exp2; exp3; exp4; exp5
         exp6; exp7; exp8; exp9 ;;
   opt1) exp2 ;;
   ...
   opt9) exp9 ;;
esac
