Invocation of Shell functions

To call a function in a shell file compiled by yourself, use the following method:

For example, you have compiled a test. Sh file as follows,

#============ Test. sh:

#! /Bin/sh
Echo_line ()
{
Echo date
Echo "Wellcome to shell func! "
}
Echo_line ()
{
Echo "Hello world! "
}
#======================================

To call the echo_line () and echo_line () methods in shell, you must first register test. Sh to the current shell.

Command:. Test. Sh

Then you can directly call the above two methods in shell.

Command:

Echo_line (call function)
Echo_hello (call function)

Note: This method requires you to register the original script to the Current Shell every time.

 

 

In addition, you can use Parameter Control in the test. Sh file to directly call it:

If ["$1" = echo_line]
Then
Echo_line
Fi
If ["$1" = echo_hello]
Then
Echo_hello
Fi
