I need to execute a os command inside a informix SPL. My informix instance runs on Solaris machine. I tried with following codes. But gives below mentioned error.
Please correct me.
CREATE PROCEDURE log_message (message VARCHAR(70))
DEFINE os_command VARCHAR(100);
-- Output message to log file
LET os_command = 'ls -ltrh /informix/nuwan/' || message || ' >> /informix/nuwan/test/data.log';
SYSTEM os_command;
END PROCEDURE;
Then I called the procedure as follows
CALL log_message('Test message...');
it give below error
668: The system command cannot be executed or it exited with a non-zero status.
2: No such file or directory
Use the SYSTEM statement to issue an operating-system command from within an SPL routine.

I have a Lua script and in there I open a minicom session which executes a script (with the -S" parameter).
local myFile = assert(io.popen('minicom -S myScript.sh ' myDevice ' -C myLogFile.log'))
local myFileOutput = myFile:read('*all')
myFile:close()
This works really fine.
But I would like to get the same output as if I execute the minicom command itself:
minicom -S myScript.sh ' myDevice ' -C myLogFile.log
Right now I don't get any output at all (I know that that's somehow obvious).
I would that the output should also occur at (at least nearly) the same time as with the minicom command itself. Not one big chuck of data at the end.
Does anyone know how to achieve that?
If I understand you correctly, you need something like
local myFile = assert(io.popen('minicom ...'))
for line in myFile:lines('l') do
print(line)
end
myFile:close()
I'm trying to install a Tcl program as a service on my Windows machine using the TclDevKit's TclServiceManager. I'm following the guide here step by step and yet I am experiencing a lot of issues.
If I try to use my raw .tcl file to create the service, I get the following error:
Error 1053: The service did not respond to the start or control request in a timely fashion.
I've followed a solution for this issue here to give the program more time to start up before the Service Control Manager terminates it; to no avail.
Then I decided to try and wrap the program using TclApp and see if that worked. Like the guide says, I used the base-tclsvc-win32-ix86.exe prefix file located in my TclDevKit bin directory. Installing the service that way, and then trying to run it resulted in the following error:
Windows could not start the <service name> service on Local Computer.
Error 1067: The process terminated unexpectedly.
There wasn't much information at all that I could find googling this error. The only Stackoverflow post on it is this one. So I tried installing the service manually through the command prompt using <TheProgram>.exe <Service Name> -install and tried running it - still gave me the same error.
Then I tried to see if I could get any useful information by running <TheProgram>.exe <Service Name> -debug and interestingly enough I got the following output:
Debugging <Service Name>.
InitTypes: failed to find the DictUpdateInfo AuxData type
abnormal program termination
Googling InitTypes: failed to find the DictUpdateInfo AuxData type leads me nowhere, however it seems to be something Tcl related.
Finally, if it means anything, the source code for the program I was trying to install as a service is some simple web server code:
proc Serve {chan addr port} {
fconfigure $chan -translation auto -buffering line
set line [gets $chan]
set path [file join . [string trimleft [lindex $line 1] /]]
if {$path == "."} {set path ./index.html}
if {[catch {
set f1 [open $path]
} err]} {
puts $chan "HTTP/1.0 404 Not Found"
} else {
puts $chan "HTTP/1.0 200 OK"
puts $chan "Content-Type: text/html"
puts $chan ""
puts $chan [read $f1]
close $f1
}
close $chan
}
if {![info exists reload]} {
set sk [socket -server Serve 3000]
puts "Server listening on port 3000"
vwait forever
} else {
unset reload
}
To check and see if the source code was the problem, I tried another, simpler example that simply created a file in a particular directory:
set filePath "C:/some/path/here";
set fileName "Test.txt";
set file [open [file join $filePath $fileName] w];
puts $file "Hello, World";
close $file;
Both programs work if you simply source them from tclsh86.exe, but give the above errors if you try and run them as services unwrapped and wrapped respectively.
Any ideas?
I am using following code to append ";C:\Python27" to environment variable PATH..
#echo off
Setx Path "%PATH%;C:\Python27" -M
PAUSE
but if i run this batch file more than once, it is appending ";C:\Python27" many times that should not happen.
SO i have to check for ;C:\Python27 before appending it to PATH variable.
Is there any command for this purpose?
The following Powershell should do it:
$needPython = $env:path | select-string -NotMatch -SimpleMatch "c:\python27"
if ($needPython) {
[Environment]::SetEnvironmentVariable("tstpath", $env:path + ";c:\python27", "User")
}
You can change User to Machine or Process to set a machine or process level environment variable.
You can run this directly from a powershell prompt.
If you're running this from a dos command line use (you need the full path to your script or .\ if it's in the current directory):
powershell "& '.\myscript.ps1'"
I am in a search of some way , using which in ruby code I should be able to create a temp file and then append some ruby code in that, then pass that temp file path to jruby -c to check for any syntax errors.
Currently I am trying the following approach:
script_file = File.new("#{Rails.root}/test.rb", "w+")
script_file.print(content)
script_file.close
command = "#{RUBY_PATH} -c #{Rails.root}/test.rb"
eval(command);
new_script_file.close
When I inspect command var, it is properly showing jruby -c {ruby file path}. But when I execute the above piece of code I am getting the following error:
Completed 500 Internal Server Error in 41ms
SyntaxError ((eval):1: dhunknown regexp options - dh):
Let me know if any one has any idea on this.
Thanks,
Dean
eval evaluates the string as Ruby code, not as a command line invocation:
Since your command is not valid Ruby syntax, you get this exception.
If you want to launch a command in Ruby, you can use %x{} or ``:
output1 = ls
output2 = %x{ls}
Both forms will return the output of the launched command as a String, if you want to process it. If you want this output to be directly displayed in the user terminal, you can use system():
system("ls")
I'm running the PHP CLI through a NSTask in MacOS, but this question is more about the CLI itself.
I'm listening to the stderr pipe, but nothing is output there no matter what file I try to run:
If the file type is not a plain text, stdout sets to ?.
If the file is a php script with errors, the error messages are still printed to stdout.
Is there a switch to the interpreter to handle errors through stderr? Do I have an option to detect errors other than parsing stdout?
The display_errors directive (can be set everywhere) takes optionally the parameter "stderr" for it to report errors to stderr instead of stdout or completely disabled error output. Quoting from the PHP manual entry:
Value "stderr" sends the errors to stderr instead of stdout. The value is available as of PHP 5.2.4.
Alternatively if you're using the commandline interface and you want to output the errors your own you can re-use the command-line nput/output streams:
fwrite(STDERR, 'error message');
Here STDERR is an already opened stream to stderr.
Alternatively if you want to do it just for this script and not in CLI you can open a filed handler to php://stderr and write the error messages there.
$fe = fopen('php://stderr', 'w');
fwrite($fe, 'error message');
If you want the error messages sent by the php interpreter should go to the stderr-pipe, you must set display_errors to stderr
This is required to return from PHP realm into shell environment in order to parse properly error message. You still need to exit(1) or whatever integer in order to return exit status code from PHP to shell.
fwrite(STDERR, 'error message'); //output message into 2> buffer
exit(0x0a); //return error status code to shell
Then, your crontab entry will look like:
30 3 * * * /usr/bin/php /full/path/to/phpFile.php >> /logdir/fullpath/journal.log 2>> /logdir/fullpath/error_journal.log
You can also use file_put_contents() with "php://stderr" to output to standard error, like:
php -r 'file_put_contents("php://stderr", "Hiya, PHP!\n"); echo "Bye!\n";' 1>/dev/null
which outputs "Hiya, PHP!\n" to standard error and nothing to standard output when executed in a Bash shell.
