head: „sh/DownloadUpdates.sh“ kann nicht zum Lesen ...

(For a wider audience, I'm using English, even though my system uses German locale as you can see)
Using wsusoffline942.zip on Linux, started from the top directory as "bash sh/DownloadUpdates.sh":
---
Download Service Packs? [y/n] n
Download .Net framework? [y/n] y
Download Microsoft Security Essentials files? [y/n] y
Download Microsoft Windows Defender definition files? [y/n] y
Please specify your proxy (default: none, http://[username:password@]<server>:<port>])
Create ISO-Image after download? [y/n] y

head: „sh/DownloadUpdates.sh“ kann nicht zum Lesen geöffnet werden: Datei oder Verzeichnis nicht gefunden
Your choice
System: w61-x64
Language: deu
Parameter: /makeiso /dotnet /excludesp /msse /wddefs
Proxy: none

Do you want to download now? [y/n] y

Obviously printheader() only works if the directory did not change since the command was started, or if an absolute path was used to start the script...

Change into the sh folder and run bash DownloadUpdates.sh from there.

So, let's try to sort this out:

The case switch in lines 44 - 60 of DownloadUpdates.sh, version 9.5:
Code: Select all
case "$OpSys" in
    Linux)
    #set working directory
    cd $( dirname $(readlink -f "$0") )
    ;;
    *BSD|Darwin)
    echo "Operating System $OpSys not yet supported"
    echo "Maybe something doesn't work as expected"
    sleep 10
    #set working directory
    cd $( dirname $(readlink "$0") )
    ;;
    *)
    echo "unknown Operating System"
    exit 1
    ;;
esac


can be replaced with all of this:
Code: Select all
# Setting up the working directory:
#
# $0 is the script name, as it was typed on the command line;
# this may be an absolute or relative path name,
# and it may include symbolic links.
#
# $canonical_name is the real path name of the script.
#
# $prog_name is the file name of the script.
#
# $dir_name is the name of the enclosing directory.
#
# Explicitly evaluating these variables step-by-step
# will also help, should the path ever contain spaces.

case "$OpSys" in
    Linux)
        #set working directory
        canonical_name=$(readlink -f "$0")
        prog_name=$(basename "$canonical_name")
        dir_name=$(dirname "$canonical_name")
        cd "$dir_name"
        ;;
    *BSD|Darwin)
        echo "Operating System $OpSys not yet supported"
        echo "Maybe something doesn't work as expected"
        sleep 10
        #set working directory
        canonical_name=$(readlink "$0")
        prog_name=$(basename "$canonical_name")
        dir_name=$(dirname "$canonical_name")
        cd "$dir_name"
        ;;
    *)
        echo "unknown Operating System"
        exit 1
        ;;
esac

# Printing all variables for debugging:
if [ $debug -eq 1 ]; then
    echo "script name:       " "$0"
    echo "canonical name:    " "$canonical_name"
    echo "file name:         " "$prog_name"
    echo "directory name:    " "$dir_name"
    echo "working directory: " "$(pwd)"
fi


The shell function printheader() in lines 315 - 318 of DownloadUpdates.sh:
Code: Select all
printheader() {
echo " "
head -20 "$0" | grep '^###'
}


can be replaced with this definition:
Code: Select all
printheader() {
    echo " "
    head -20 "$canonical_name" | grep '^###'
}


I hope this helps,
Hartmut
