Good to see, everything’s alright then. proc:system will only output a
result if the command was executed successfully.

I would expect just some text, as with proc:system("ls")

How does the output look like?

If the code 1 is raised, it indicates that your command will be
executed indeed, but it returns the exit code 1.
Hi Christian,
Interestingly, proc:execute("/usr/local/bin/tesseract") works (I have BaseX
9.2).
proc:system("/usr/local/bin/tesseract") returns the following:

Hi,
When I try to run
proc:system("/usr/local/bin/tesseract") I get the error [proc:code0001]
Similarly:
proc:system("tesseract") returns [proc:error] Cannot run program "tesseract":
error=2, No such file or directory
Similarly:
proc:system("tesseract", (), map {"dir" :
Hi Kristian,
You may be glad to hear that we recently had a similar requirement. I
have revised and extended the Process Module and uploaded a new
snapshot [1,2].
Looking forward to your feedback,

Hello!
I need to redirect the content of a file into a program using stdin. In
my shell I would do like this (silly example):
wc < somefile
Is this possible to do with proc:system? Giving "<" as an argument to
the command doesn't work:
proc:system("wc", ("<", "somefile")) outputs
Andy,
Thank you for your answer. Indeed, the length of my parameters are now much
more than the Windows limit.
I guess that creating a temporary file, then passing the name of the file
as parameters should solve the issue.
Cheers,

Hi Jean-Marc,
I have hit this kind of issue before and it is not BaseX specific. The
problem is Windows(tm) limits [1]
This is compounded by the Java call from proc:system passing in a copy of
the environment of the current process [2].
Mine has built up a large class path over time with my
Hello BaseX team,
I am an extensive user of the proc:system BaseX command (and looking
forward for proc:fork !).
I am using this command with in-memory arguments, it means that my way of
using it is :
proc:system("my_exe", $my_arguments_for_exe)
$my_arguments_for_exe is an xml node serialized
11 matches
