  • file occupied

    From zeneca@21:1/5 to All on Tue Jul 5 09:52:24 2022
    I wrote a program run every 5 minutes from a bash script.
    It run ok, but when I reboot it doesn't start giving :

    -bash: ./nokia: Fichier texte occupé
    ( text file occupied )
    ??
    I can't run it manually, same error.
    to solve this I have to recompile no changes in source code ( C)
    any idea ?
    Many thanks

    If you can reproduce, run the program with "strace":
    strace -fo nokia.out ./nokia
    and then search the file "nokia.out" for "ETXTBSY".

    The error itself means that the program tries to open some executable
    file (or a shared object) for writing but that file is currently in use.

    Are you sure your script or compiled program isn't attempting to overwrite
    the compiled binary?

    lsof may show you what's going on:

    "lsof -- ./nokia | less" - piping lsof through less is a good idea because
    lsof can produce a lot of output.

    How is the wait handled? If you're running something like

    stop = 0
    while (stop)
    do
    nokia
    sleep 5m
    done

    consider rewriting it as a cron script instead As an example, my internet connection is slow often enough that I check its speed every 10 minutes
    with this cron script in /etc/cron.d


    #
    # Run at 15 minute intervals
    # ==========================
    # Results are sent to root
    #
    MAILTO=root

    2,17,32,47 0-23 * * * root /usr/local/bin/adslchk -b 2>&1 >>/var/log/
    adslchk


    This cron script runs the "/usr/local/bin/adslchk -b 2>&1 >>/var/log/
    adslchk" command at 2,17,32,47 minutes after each hour and writes the
    script output to /var/log/adslchk.

    The advantages of this approach are that:
    - the process is automatically started when the computer is rebooted
    - the adslchk script only runs for a few seconds each time its started
