Shell脚本编写以形成动态数组并基于该数组触发一个过程

老派的POSIX外壳：

#!/bin/sh

# Note: Inside the functions, $@, $1 etc. refer to the arguments to the function,
# whereas outside they refer to the arguments to the whole script.    
foo() {
    echo foo $@
}

bar() {
    echo bar $3 $2 $1 
}

PARAMS=

while [ $# -gt 0 ]; do    # while there are arguments
    case "$1" in          # check if the front argument is a command
    foo)                  # if so, run it with the previously cached parameters
        foo $PARAMS       # (see below)
        PARAMS=
        ;;
    bar)
        bar $PARAMS
        PARAMS=
        ;;
    *)                    # if it is not a command, cache the parameter in the
        PARAMS+=" $1"     # $PARAMS variable
        ;;
    esac

    shift                 # shift the arguments back; what was $2 is now $1
done

称为./foo.sh 1 2 foo 3 4 5 bar，这给出了

foo 1 2
bar 5 4 3

如果您需要使用bash数组，则其语法为

PARAMS=()       # instead of PARAMS=
PARAMS+=("$1")  # instead of PARAMS+=" $1"
${PARAMS[0]}    # instead of $1, analogous for $2, $3 etc.

其余部分保持不变，当然，您可以使用参数数组调用函数以外的其他事情。
