Hey I am trying to understand the command goto.
I have some questions regarding the goto manual.
1.
Quote:
Goto is allowed only when the Shell is taking commands from a file.
What does the underlined part mean?
I'm not allowed to type goto in the shell? But if goto is written into a file everything is okay?
2.
Quote:
The file is searched from the beginning for a line beginning with `:' followed by one or more spaces followed by the label.
So if a part of my file looks like this
Code:
...
goto end
...
Then he would look for a part like this
Code:
: end
But I have seen some scripts and I think they were from Unix v6, it looked everytime like this
Code:
end:
So what is now the right order?
3.
Quote:
If such a line is found, the goto command returns. Since the read pointer in the command file points to the line after the label, the effect is to cause the Shell to transfer to the labelled line.
Is it legal to write any other command in the line with the ":"?
For example
Code:
:end echo "Hello"
or
Code:
end: echo "Hello"
I'm not expecting that one person answers all 3 questions, you can pick the one you like.
Thank you for your help
and Merry Christmas
Ps. I mean this manual: v6shell.org/man/goto.1.html

Is there a Unix (Solaris v8 ksh) version of the old basic command gosub or goto? I've researched the return command, but can't identify the command to return from. I am not trying to return from a function. Can someone give me a basic understanding of this please? Thanks so much in advance for... (3 Replies)
1) Can a script be made to ignore all signals.
2) Does the parent process always picks up the exit status of its children.
3) Can one program give rise to multiple processes.
4) Is a file is synonymous with a process.
5) Is the kill command only used to kill a running process. (1 Reply)

Well, guys I saw a question about GOTO for Python.
So this gave me the inspiration to attempt a GOTO function for 'dash', (bash and ksh too).
Machine: MBP OSX 10.14.3, default bash terminal, calling '#!/usr/local/bin/dash'...
This is purely a fun project to see if it is possible in PURE... (3 Replies)
