I have many BASH scripts called in sequence, eg, script1.sh contains:

(我有许多顺序调用的BASH脚本，例如script1.sh包含：)

#!/bin/bash

bash script2.sh
bash script3.sh
bash script4.sh

script2.sh contains:

(script2.sh包含：)

#!/bin/bash

file_a="1.txt"

cp $file_a /tmp/$file_a.tmp

script3.sh contains:

(script3.sh包含：)

#!/bin/bash

wc -l /tmp/$file_a.tmp

script4.sh contains:

(script4.sh包含：)

#!/bin/bash

cat /tmp/2.txt $file_a.tmp > file3.txt

Each file requires access to a small collection of variables.

(每个文件都需要访问少量变量。)

Answer 1

You have many options.

The first method would be making the variable as the environment variable and pass to the script before the second script get executed.

(第一种方法是将变量设为环境变量，并在执行第二个脚本之前将其传递给脚本。)

The second method would be making the second script to run in the same shell.

(第二种方法是使第二个脚本在同一shell中运行。)

The methods are described well here with the examples.
