Beginner question - testing for null string from shell script command

I'm trying to test the result of a shell script command. I want to put out a message if the result is a null string. At present I get this applescript error "The command exited with a non-zero status"
I'm sure this is a simple question ... but I can't figure out how to do it. Help!

You can use try clause for the problem:
set _result to ""
try
set _result to do shell script "/blah/andblah"
end

Test for null result set

I am trying to do a test for a null result set. Basically if the result set returns a value I want to display a table, otherwise I want to display an error message. The following code does not produce the error message. Either the test for null is incorrect, or for some reason I am not getting a null result set even when I don't enter any text into the following text boxes (this is for a login screen, these text boxes come a login screen):
<input type="text" name="username">
<input type="text" name="password">
This is the code for the action page:
<HTML>
<%@page import="java.sql.*"%>
<%
//define connection
Connection con = null;
String user1 = request.getParameter("username");
String pass1 = request.getParameter("password");
String test = "good";
try{
//get the class
Class.forName("sun.jdbc.odbc.JdbcOdbcDriver");
//get the connection
con = DriverManager.getConnection("jdbc:odbc:errorlog", "admin", "");
//catch your exceptions!
catch(Exception e){
out.println(e.getMessage());
%>
<title>Error Application - Logged Errors</title>
<link href="style/errorstyle.css" rel="stylesheet" type="text/css">
<BODY>
<%
//define resultset and statement
ResultSet rs=null;
Statement stmt=null;
try {
//Using the current database connection create a statement
stmt=con.createStatement();
%>
<%
String sql="SELECT* FROM tblUsers" + " WHERE Username = '"+user1+"' AND Password ='"+pass1+"'";
rs = stmt.executeQuery(sql);
%>
<% //Fetch all the records and print in table
while(rs.next()){
String user2 = rs.getString("FirstName");
String pass2 = rs.getString("LastName");
%>

<td width="89" bgcolor="#999999"><strong><font size="-1">Last
Name</font></strong>
</td>
</tr>
<tr>
<td>
<%out.println(user2);%>
</td>
<td><%out.println(pass2);%></td>
</table>
<%}
if (rs == null)
out.println("Incorrect Username or Password");
//close all your open resultsets, statements, and connection when you are done with them!
rs.close();
stmt.close();
con.close();
//catch all your exceptions
catch (SQLException e) {
out.println(e.getMessage());

You simply test the rs.next().
if ( rs.next() )

Passing long string to shell script from java

I am trying to passa a long string to a shell process through java,
call is like
Runtime rtime = Runtime.getRuntime();
String callAndArgs[] = {"/apps/jetty4/jstest/jstest.sh",jarCo,queue,text};
Process child = rtime.exec(callAndArgs);
here the string text is :
|HEADER|JAR933|[email protected]|290001|OL0006528|WIN4015444|SHAFT_FORGING|1.0|Baan EDM|||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||
|290001|WIN4015444|00||||2|SHAFT FORGING|9|AXELSMIDE|3|ACHSE SCHMIEDEST�CK|4|ARBRE FORG�|f|AKSELITAOS|||||||||||||||||||||||No||Approved|41.0|Mechanic|Yes|pc||WIN4015444|EL20|Purchased|Metric||0|20051120|||||Released||||||||||||||||No||||||||||||||||||||||||||||||||
Now i use this string in shell script to pass as an argument to other class. But the string gets truncated.
How do i solve this?

It appears that your os is truncating the data - Java's not involved.
Maybe write the data to a file and then read it into the external program some way.

Problem while calling concsub from shell script

Hi All,
I am facing problem when I am trying to run CONCSUB utility from shell script.The same works well when I try it from command line.The only prob I am facing from shell script is assigning values to temporary variables.
This is how my script looks
#!/bin/bash
export PARM5="$5"
export PARM6="$6"
export PARM7="$7"
echo "INTPARM5=\"$PARM5\""
echo "INTPARM6=\"$PARM6\""
echo "INTPARM7=\"$PARM7\""
echo $FND_TOP/bin/CONCSUB $1 ONT 'Order Management Super User, Vision Operations (USA)' $3 WAIT=Y CONCURRENT ONT $PROGRAM "$INTPARM5" "$INTPARM6" "$INTPARM7"When I try to run the above shell based concurrent program it doesn't pass the parameters as expected and it errors out saying "Wrong number of arguments to call the procedure"
I tried my luck from some of the previous posts ({thread:id=2360776} ),but to vain
If anyone has any ideas,please suggest!!
Thanks in advance!!

Wait for a "do shell script" command to finish

i have an applescript that has to call a few external applications. i currently do this by setting the exact syntax of the external command in a string variable, then issue a "do shell script cmd" (seen many examples across the net using this standard)
my applescript continues beyond these commands. how do i set the applescript to either wait for the above external command to finish, or not?
regards
jingo_man

Usually AppleScript will wait for a shell script to complete before it continues, but adding an ampersand (&) at the end of the shell script command will make it run in the background, which allows the AppleScript to continue. See Technical Note 2065: do shell script in AppleScript for more information.

Urgent Problem in Executing perl script from shell script

Hello,
I've a shell script on one server (source) and a perl script on another (target).
My perl script will check whether the directoryname, filename provided by shell script exists on the target server or not.
My shell script is as follows:
#! bin/bash
cmd=`ssh user@target "perl /home/user/test_dir/validate_file.pl"`
echo $cmd
And my perl script uses a package CU_Functions.pm, which is in the same directory as the perl script on the target server.
But when I invoke the perl script from shell script, I get the following error:
Source:user> (db:ias10g12_mid_db) /home/user/perl
$ sh /home/user/arcs/arcs_conn.sh
user@target's password:
Can't locate CU_Functions.pm in @INC (@INC contains: /local/perl-5.6.1/lib/5.6.1/i686-linux /local/perl-5.6.1/lib/5.6.1 /local/perl-5.6.1/lib/site_perl/5.6.1/i686-linux /local/perl-5.6.1/lib/site_perl/5.6.1 /local/perl-5.6.1/lib/site_perl .) at /home/user/test_dir/validate_file.pl line 13.
BEGIN failed--compilation aborted at /home/user/test_dir/validate_file.pl line 13.
Please let me know if I need to do any configurations prior to call the perl script.

As for the Perl INC, I cannot recall the environment variable that sets that but the following example should work:
ssh user@host "export ENV_VAR=/path/to/include/files:$ENV_VAR ; /full/path/to/script"

Passing parameters from shell script to OWB process flow

Hi all,
I am running OWB process flow (using the template script provided by oracle) and i want to pass two date parameters as shown below:
sqlplus -s $SQL_USER/$SQL_PWD@$ORACLE_SID @$HOME_DIR/src/vmc_oem_exec_script.sql OWB_OWNER VMC_POST_DW_PF_LOC_SIT PROCESS VMC_NM1_PORT_MAIN "," "P_DATE_FROM=$DATE_FROM,P_DATE_TO=$DATE_TO"
How do i catch those values in process flow and pass those to mappings in Process flow?
Do i need to create PF variables with same names or any name will do?
Thanks in advance

This document is explaining how to pass data between activities in process flow.
I am passing parameters from a shell script.
Any ideas,how to pass parameters from shell script and then initialize the process flow variables based on those values and then pass them further to mappings.
Thanks

Exports (from shell script) without password given explicitly in script

Hi All,
I have Oracle 10g2 on SLES 10 64-bit. I would like to do export the database using data pump from shell scripts. Is there any method to hide the password in the script file.
Currently in doing by command:
expdp system/password@database ....
So any user who see the script will know the passowrd.
Regards
Groxy

Hi,
Have you considered the "Secure External Password Store" feature that was added in 10gR2? It uses the Oracle Wallet to store a database_alias with username/password credentials in encrypted format. Then you can enter your expdp command like this:
expdp /@database_alias ...
Take a look at the 10gR2 Security Guide. There's a chapter there on how to set this up.

Which .bash does "do shell script" commands use?

The "do shell script" command uses the Bourne shell "sh". But I am curious to know which .bash it uses to define the shell environment variables.
I ran into a problem installing a third-party unix program which required new environment variables to be defined in order to execute. Defining these variables and executing this program from the terminal worked fine.
But executing it within a "do shell script" command in an Applescript - the program died silently because the environment variables it required were not defined in the shell Applescript uses. It appears to invoke a new shell which does not inherit the environment variables defined in your home user shell.
(I found this out by 'do shell script "set"' which listed the environment variables Applescript knows about - the ones I defined for the third-party program were not listed).
A "brute force" way of fixing this is to pass the environment variables directly:
do shell script "export THIRDPARTY_ENVVAR=blah; /usr/sbin/thirdpartyprogam"
This works but not exactly elegant, particularly when you need to pass a number of variables.
So - any better ways to do this? Can I edit the .bash Applescript uses, and where is it?
Thanks.

Another option that might work for you... if you are saving/distributing your AppleScript as an "Application bundler" is to group all your shell env. variables and other commands into a separate shell script file. Then include the shell script inside your app bundle. Locate the shell script at runtime and run that with "do shell script".
For example, create "myShellScript.sh"
#!/bin/sh
export THIRDPARTY_ENVVAR=blah
# ... more variable declarations..
/usr/sbin/thirdpartyprogam
# ... more shell commands...
Store the shell script file inside your AppleScript bundle's Contents -> Resources folder (remember to make the shell script executable). Then your AppleScript can find your shell script at runtime and execute it like this:
set ssPath to quoted form of POSIX path of (path to resource "myShellScript.sh")
set stdout to do shell script ssPath

Complex shell script command

HI Experts
can anybody know what this complex shell script command is doing .. i know its looking for some character at some point but exact explanation will be good for learning.
egrep "^.{292}[CFOPRA][EPR]$" dn.dat
Thanks

A simple example can often demonstrate how things work:
# cat sample.dat
xABCDE1
xABCDE2
ABCDE3
ABCDE4
xDBCEA5
xDBCEA6
# egrep "^.A" sample.dat
xABCDE1
ABCDE4
Above matches lines that begin with any character followed by an "A".
# egrep "^.{2}A" sample.dat
xABCDE2
Above matches lines that begin with any 2 characters followed by an "A".
# egrep "^.{2}[AD]" sample.dat
xABCDE2
xDBCEA6
Above matches lines that begin with any 2 characters followed by an "A" or D".
# egrep "^.{6}[345]$" sample.dat
ABCDE4
xDBCEA5
Above matches any lines ending with "3", "4" or "5",
provided it's the 7th character.
# egrep "^.{5}[345]$" sample.dat
ABCDE3
Above matches any lines ending with "3", "4" or "5",
provided it's the 6th character.
# egrep "^.{6}[EA][26]$" sample.dat
xABCDE2
xDBCEA6
Above matches any lines ending with combinations of "E2, E6, A2, A6",
provided the combination starts at character position 7.

Trying to test for null input

I am trying to get some input from a user using:
String name="";
BufferedReader in = new BufferedReader(
    new InputStreamReader(System.in));
name = in.readLine();Let's say the user inputs nothing other than the enter key, how can I test for this so that I can write output for it?
In Python, one would use something like:
if not name:
     <then do something>Thanks,
Harlin Seritt

Thanks for the help. When I try it with an empty
string test, nothing happens. However, the test of
name.length() works perfectly. Thanks!
Harlin SerittI'm guessing you tried this, right?
if (name == "") ...
That's not the way to compare string values. The == operator only compares object references when comparing 2 objects. It's an extremely common mistake.
