菜鸟求教，在线等待：case语句后报双分号错误

i=0
comvar=(c,m,l,w,L)
len=$(#array[*])
while [ $i -lt $len ]; do

  case "${comvar[$i]}" in
  "c") echo "bytes: "
  wc -c program1.sh;;
  "m") echo "chars: "
  wc -m program1.sh;;
  "l") echo "lines: "
  wc -l program1.sh;;
  "w") echo "words: "
  wc -w program1.sh;;
  "L") echo "max-line-length: "
  wc -L program1.sh;;
  esac

  let i+=1
done
程序老是报错说里面的;;错误。

做了一下修改，去掉""

C/C++ code

#!/bin/bash
#jernymy case array test

i=0
comvar=(c m l w L)
#len=(#array[*]) #jernymy
len=${#comvar[*]} #jernymy array length use

echo "len=" $len

while [ $i -lt $len ]; do
    case ${comvar[$i]} in
        c) echo "bytes: "
        wc -c program1.sh
        ;;
        m) echo "chars: "
        wc -m program1.sh
        ;;
        l) echo "lines: "
        wc -l program1.sh
        ;;

        ;;
        *) echo "default"
        ;;
    esac
    let i+=1
