Shell learning: Calling between scripts

For Java,python, you can use the import method to make calls between scripts or modules, for example:

>>> Import math>>> math.sqrt (4) 2.0

how to invoke other shell scripts in the shell. Or a variable in another script, what about the function?

method One: . . /subscript.sh

Method Two: Source ./subscript.sh

Attention:

• There are spaces between the two points. Never mind.
• Two scripts are not in the same folder. To use an absolute path
• For simplicity, pass often uses the first method

Like what:

• Main.sh #主脚本
• Subscripts.sh #子脚本, or the script that was tuned

# # #subscripts. sh script contents such as the following: ####!/bin/bashstring= "hello,world! \ n "

# # #main. sh script contents such as the following ####!/bin/bash. ./subscripts.shecho-e ${string}exit 0

Output Result:

# chmod +x./main.sh#./main.shhello,world!#

Note:

• The called script can have no running permissions. Call script must have operational permissions
  
• chmod +x./main.sh #注意这里要有点, otherwise the bash script may find less than
