我可以在 bash 中调用交互式脚本吗？

Question

For example,there is an interactive script that read user input his name.And then write the name in a file.

#! /bin/bash 
read name
echo $name>>name.txt

If I can't change the interactive script, how can I use anothor bash to quote the interactive script?

For example,I want to write a bash that extracts the name from a text and then calls this interactive script.

So can I achieve my idea?

Answer 1

Use a pipe to combine output of one program with the input of the next program:

echo 'name from other script' | ./script1.sh

echo can be replaced with any other executable file or script:

$ cat >script2.sh
#!/bin/sh
echo 'first input'
echo 'second input'
^D
$ chmod u+x script2.sh
$ ./script2.sh | ./script1.sh

If your intended input name is already in a file, use IO redirection instead:

$ ./script2.sh < file_containing_name.txt
