• Bash script

    From Rick Smith@1:105/10.1 to All on Sat Jun 19 11:30:12 2021
    Greetings All!

    I believe this is where this ? goes...

    Not sure if this is where I would ask this question or not? I am trying to make bash script to combine a
    couple of other scripts and I had a couple of questions. So If I make a script that performs something
    and then it calls say another script, would the first script then pause until the called side script
    completes? If not is there a way to make it wait to move forward until the other one completes? I hope I
    am describing this well for you.

    bash start_end_off_world.sh && bash stop_end_off_world.sh

    ?

    if start_end_off_world.sh will not end, then the 2nd stop_end_off_world.sh will not be called

    hopefully more linux geeks can stop it :)

    Hey Rick!

    So If I make a script that performs something and then it calls
    say another script, would the first script then pause until the
    called side script completes?

    That is the normal behavior.

    If not is there a way to make it wait to move forward until the
    other one completes?

    -={ '<Esc>:read !wait --help' starts }=-
    wait: wait [-fn] [-p var] [id ...]
    Wait for job completion and return exit status.

    Waits for each process identified by an ID, which may be a process ID or a
    job specification, and reports its termination status. If ID is not
    given, waits for all currently active child processes, and the return
    status is zero. If ID is a job specification, waits for all processes
    in that job's pipeline.

    If the -n option is supplied, waits for a single job from the list of IDs,
    or, if no IDs are supplied, for the next job to complete and returns its
    exit status.

    If the -p option is supplied, the process or job identifier of the job
    for which the exit status is returned is assigned to the variable VAR
    named by the option argument. The variable will be unset initially, before
    any assignment. This is useful only when the -n option is supplied.

    If the -f option is supplied, and job control is enabled, waits for the
    specified ID to terminate, instead of waiting for it to change status.

    Exit Status:
    Returns the status of the last ID; fails if ID is invalid or an invalid
    option is given, or if -n is supplied and the shell has no unwaited-for
    children.
    -={ '<Esc>:read !wait --help' ends }=-

    Of course you only need to do this when the script is running parallel processes where the output from one is needed for another.

    Life is good,
    Maurice

    trying to make bash script to combine a couple of other scripts

    bash plus bash or bash plus non-bash scripts??

    If I make a script that performs something and then it calls say
    another script, would the first script then pause until the called
    side script completes?

    Yes. A script is basically a list of commands running in sequence one by one.

    ls A*
    ls B*

    would list all files with A* and then all files with B*.

    A command is basically an executable programm or another script.

    Many shells have internal commands for workflow control like loops and breaks.

    If not is there a way to make it wait to move
    forward until the other one completes?

    Yes. On many conditions.

    man bash
    man test

    should be your friend. Take your time and use the search function of man and type /loop for example. Jump with n to the next hit. Or press h for the help file.

    Regards

    Kai

    Calling another script is just like calling another program. It
    will wait for it to finish before continuing unless you run it in
    the backgound.

    Really? This looks confusing to me now.

    Well, jump with n is not a man search function. man used less to display text on my system so n is a search function of less.

    I'll wrap the two in brackets so an offline quote won't confuse you.

    { cat file > results.txt } write the results of "cat file" to results.txt
    as a NEW file.

    {cat file2 >> results.txt } -appends- the results of "cat file2" to results.txt
    which follows the results of "cat file".

    I suppose something like that might just need to be tested.
