Some summary of shell script usage

(1), the CSH script can call Bash's script, and vice versa.

(2). How to invoke variables and functions defined in other scripts.

(3). The variable defined, which defaults to a global variable. Local variables need to be specified locally to declare them. Column: Local value= "value",

The variable cannot be called in any other function or file.

(4). Execution is loaded (included)

L Example: the variable and function defined in test.sh are called in use.sh.

TEST.SH is defined as follows:

#!/bin/sh

function func

{

echo "The ARG is $"

Value= "$"

echo "Value=${value}"

}

Function Main

{

echo "--main Start---"

Func "Test"

echo "---main end---"

}

The following is the definition of main.sh

#!/bin/sh

source./test.sh # (or./test.sh), you need to indicate the path to the containing file---(4)

echo "---use Start---"

Main

echo "Call Value =${value}"

echo "---use End---"

---------------------

Execute main.sh (or sh-x main.sh)

You can see the call procedure.
