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 ...

To keep the forums high quality for all users, please take the time to format your posts correctly.

First of all, use Code Tags when you post any code or data samples so others can easily read your code. You can easily do this by highlighting your code and then clicking on the # in the editing menu. (You can also type code tags [code] and [/code] by hand.)

Second, avoid adding color or different fonts and font size to your posts. Selective use of color to highlight a single word or phrase can be useful at times, but using color, in general, makes the forums harder to read, especially bright colors like red.

Third, be careful when you cut-and-paste, edit any odd characters and make sure all links are working property.

Thank You.

(sorry for my english)

i supose every of your scripts returns a code,
0 = Ok
1 = No ok
then yo can do:

if script1.sh params
then
....your code
if script2.sh params
then
..... your code....
else
echo "ERROR in script2.sh"
fi
else
echo "ERROR in script1.sh"
fi
------------------------
example with a command:

$more file
if cat $1
then
echo "cat execute OK"
else
echo "cat execute NO-OK"
fi

No - and that is the problem.
i get return-code "0" everytime - even when the script runs till end but the xml-file is corrupt or missing ...
Code:
 
 
Hereīs an example:
 
XML-File is ok:
/usr/bin/php5 script1.php; echo $? -> returns "0"
 
XML-File is corrupt:
/usr/bin/php5 script1.php; echo $? -> returns "Can /srv/www/htdocs/_source/xml-file not read".0

two ways:
1- Can you modify the sripts?
2- Redirect stdout of scripts.pp, if script is OK the file size is 0 but if script is NO OK the size is not 0 becaus the are the string "Can /srv/www/htdocs/_source/xml-file not read"
/usr/bin/php5 script1.php >/tmp/script1.$$
if [ -s /tmp/script1.$$ ]
then
echo "Error"
else

fi
rm -f /tmp/script1.$$

Note probe if thestring "Can /srv/www/htdocs/_source/xml-file not read" go out by stdout or by stderr, if is the last (stderr) de redirection is 2>

if you don tmp files you can probe:

buffer=`/usr/bin/php5 script1.php`
#be sure the content of buffer
echo "[$buffer]"
if [ "$buffer" ]
then
echo "Error"
else
echo "OK"
fi

Version 2 works fine ... many thanks for your help.

... have just seen,
when the script runs and thereīs an error-message in /tmp/script1.$$
how can the error-message be displayed in the logfile, too?

Code:
 
/usr/bin/php5 script1.php >/tmp/script1.$$
if [ -s /tmp/script1.$$ ]
then
echo 'Script 1 was not read - Error - & **display error-message** '
else
echo 'Script 1 was read - Success'
fi
rm -f /tmp/script1.$$

Code:
echo 'Script 1 was not read - Error -\n `cat /tmp/script1.$$`  '

Code:
echo 'Script 1 was not read - Error "
cat /tmp/script1.$$
