C-Linux-Any way to pass command “history” to Linux shell?

Question

I'm writing a C program to run in Linux system. The program will pass some Linux commands to shell and receive the result with txt files.

system("last >> last.txt");
system("ls -s >>ls.txt");

But I failed with "history" as someone told me that this is not a command but a buildin.

So is there any way I can pass "history" as other ones?

Thanks!

Answer 1

You might also be able to actually invoke the built-in command by using the shell:

system("bash -e \"history >> history.txt\"");

Change "bash" to the preferred shell.

Answer 2

“history”相当于“cat~ / .bash_history”，所以替代方法是使用：

system("cat ~/.bash_history");

Answer 3

Depending on the shell used you can look at the history file.

For example: ~/.bash_history or ~/.zsh_history.
