Just got to work and got the same error that Jorge Eduardo Perez Perez got on Windoze. I'll see if it is something I can track down quickly/easily enough to resolve things.

[wbuchanan]

Not sure what is happening, but I think it may be related to the .pkg file on the github pages site. When I tried installing it on my Ubuntu box at home I had the same issue, but when I looked in the directory the jar file hadn't been installed. When I copied the .jar file to the directory manually it worked with out any issues. I might need to sandwich the jar between a helpfile and the .ado or something strange like that:

. about

It might be something where it isn't loading the jar on your side as well, or it may not be looking for it in a jar subdirectory instead of the directory where the ado file resides.

[Jorge Eduardo Perez Perez]

Current version is working on both of my systems. Amazing, thanks!

[wbuchanan]

Jorge Eduardo Perez Perez Cool glad to hear it. I threw a help file in just to see if that was potentially related and was able to test it successfully on my Mac, but it failed again on my Linux machine this morning (but that may be more an issue with permissions than anything).

[Jorge Eduardo Perez Perez]

eric_a_booth Thank you for the help with file read. I think I'll just switch to sysresources now, but your code helped me learn about how file read works.

[Jorge Eduardo Perez Perez]

I have been using sysresources successfully for a while now, but now there's a lot of disk caching going on in the server. sysresources can not see the cached memory, only the physical memory and the swap space. This means that sometimes my processes stop because of lack of available physical memory, while in fact they could grab it from the cache and start. Is there a chance you could update sysresources to also return the cached memory?

Thanks again.

[wbuchanan]

Jorge Eduardo Perez Perez I'll try to see if I can find a way to get the cached memory from the system as well. If I can I'll definitely add it. If you wouldn't mind, though, submit this as an issue to the project repository. It helps me to keep track of and manage my queue and also provides a bit of information about what drove any changes/updates.

[Jorge Eduardo Perez Perez]

Sure I'll post it there. Thank you!

[wbuchanan]

Jorge Eduardo Perez Perez not a problem. Glad it has been helpful.

[wbuchanan]

The program has been updated and the addition basically acts like the shell or ! command, but returns the result in local macros. So the syntax would look something like :

 
sysresources vm_stat

With no other options (which I still need to document), it will attempt to parse the lines from stdout into key value pairs defined by multiple repeated white space characters, and will then attempt cleaning the key and value elements (e.g., trimming the keys to 32 characters and replacing any spaces with underscores). The set up right now means that things are fairly OS dependent, but also means you could do things that are more familiar from the command line (e.g., grepping output from the top command) as well. I'll probably make the default behavior return the individual lines from stdout without any processing, but there is also a macro that returns the raw results that you could parse separately if you wanted. There's an example of what the return values look like on OSX on the project page and in the README file in the repository.

[wbuchanan]

eric_a_booth can you try running:

ado, find(sysresources)

Just to make sure there isn't a second copy floating around somewhere. I actually just broke things out a bit more and was getting ready to push the changes this morning (e.g., the modification mentioned by Jorge Eduardo Perez Perez will now be contained in a separate command called clicmd which can be used more generally to make calls to the shell and get the results returned back into Stata). As an example based on Jorge Eduardo Perez Perez's request, this is the closest thing I could find for OSX and the command itself is ported from Unix so it should satisfy the need (assuming Jorge Eduardo Perez Perez is a bit more familiar with the man page entry and language in the entry than I am [not sure which of the entries would show the cached memory but could guess]):

Without any regular expressions being passed it will try to split things into key-value pairs and return the regular expressions used to do that (e.g., r(cleaner), r(parser), r(clgroups), and r(pgroups)). Right now it's primarily useful for cases where the command is a single string without spaces, but I'll continue looking into ways to pass options/flags and arguments to the commands in a way that Java doesn't complain too much. If the parse/clean options are not turned on, the data will be returned in macros defined by the line number of the output:
