Help Syntax Shell-Script
Hi Guys,
iīve a question ... but itīs a litte bit tricky:
iīve a 3 php-scripts which runīs via cron at night. These script reads an xml-file a writes it in an MySQL-DB.
I named them (for example here ) Script1 - Script3. The XML-Files i named xml1 - xml3.
Now, iīve build a Batch-file, which will start the php-scripts an should write success or error to a log-file ...
And hereīs my problem:
When Script1 starts, it reads xml1 - when xml1 is alright, script1 runs till the end and thereīs no output - "echo $?" returns with "0"
Now, (error-example) when Script1 starts, it reads xml1 - when xml1 is missing or corrupt, script1 runs till the end too and thereīs an output called "Can /srv/www/htdocs/_source/xml-file not read."
This is an order at the end of script1 (and script 2 & 3 of course)
When i type "echo $?" it returns "0", too.
And hereīs my second problem:
my logfile should looks like this:
"Script1 was read - success" (-> when script1 ends with no errors, xml-is fine)
"Script1 was read - error" - Can /srv/www/htdocs/_source/xml-file not read." (-> when script1 ends with errors.)
Can somebody help me with the syntax to write my batch-file:
Hereīs are my first steps/trials ...
#! /bin/sh
# Description
cd /srv/www/htdocs/import (here are the 3 scripts)
/usr/bin/php5 script1.php;
if [ $ ... donīt know]
then
echo ' Script1 was read - success' ;
else
echo ' Script1 was read - error' - Can /srv/www/htdocs/ ... ' ;
fi;
... and so on till Script3
Many Thanks.
Regards,
Michael

Hope, my explanations are plausible. If not, feel free to ask ...

jrunscript
jrunscript(1) General Commands Manual jrunscript(1)
NAME
jrunscript - command line script shell
SYNOPSIS
jrunscript [ options ] [ arguments... ]
PARAMETERS
options
Options, if used, should follow immediately after the command name.
arguments
Arguments, if used, should follow immediately after options or command name.
DESCRIPTION
jrunscript is a command line script shell. jrunscript supports both an interactive (read-eval-print) mode and a batch (-f option) mode of
script execution. This is a scripting language independent shell. By default, JavaScript is the language used, but the -l option can be
used to specify a different language. Through Java to scripting language communication, jrunscript supports "exploratory programming"
style.
NOTE: This tool is experimental and may not be available in future versions of the JDK.
OPTIONS
-classpath path
Specify where to find the user's .class files that are accessed by the script.
-cp path
This is a synonym for -classpath path
-Dname=value
Set a Java system property.
-Jflag
Pass flag directly to the Java virtual machine on which jrunscript is run.
-l language
Use the specified scripting language. By default, JavaScript is used. Note that to use other scripting languages, you also need to spec-
ify the corresponding script engine's jar file using -cp or -classpath option.
-e script
Evaluate the given script. This option can be used to run "one liner" scripts specified completely on the command line.
-encoding encoding
Specify the character encoding used while reading script files.
-f script-file
Evaluate the given script file (batch mode).
-f -
Read and evaluate a script from standard input (interactive mode).
-help
Output help message and exit.
-?
Output help message and exit.
-q
List all script engines available and exit.
ARGUMENTS
If [arguments...] are present and if no -e or -f option is used, then the first argument is the script file and the rest of the arguments,
if any, are passed as script arguments. If [arguments..] and -e or -f option are used, then all [arguments..] are passed as script argu-
ments. If [arguments..], -e and -f are missing, interactive mode is used. Script arguments are available to a script in an engine variable
named "arguments" of type String array.
EXAMPLES
Executing inline scripts
jrunscript -e "print('hello world')"
jrunscript -e "cat('http://java.sun.com')"
Use specified language and evaluate given script file
jrunscript -l js -f test.js
Interactive mode
jrunscript
js>print('hello world');
hello world
js>34 + 55
89
js> thread(function() { print('hello world'); }
hello world
js>
Run script file with script arguments
jrunscript test.js arg1 arg2 arg3
test.js is script file to execute and arg1, arg2 and arg3 are passed to script as script arguments. Script can access these using "argu-
ments" array.
SEE ALSO
If JavaScript is used, then before evaluating any user defined script, jrunscript initializes certain built-in functions and objects. These
JavaScript built-ins are documented in jsdocs.
