Can anyone please let me know how to call a perl script from a Windows powershell script (.ps1)?
You simply run it with the perl executable:
perl myscript.pl

I am trying to use cheerio in a bash script. No matter how I install it I cannot get cheerio to be a command that can be executed on the command line
Is it not meant to work this way? I'm confused.
I have created pkg using packageMaker. It contain preinstall and postnatal script along with other plugin files. when i am trying to install it, its get installation failed message. I did research and find that preinstall scripting is failing this installation.
But when i tried to run preinstall script from terminal. script is working without any error.
Looking for some help.
Go to the log (Cmd + L) after the installation fails and see which specific line of your postinstall script failed.
I was also facing this issue with my project installer. The installer for me was failing as there was some issue in my script.
In my preinstaller script which was a shell script, I had some command for which the command line argument length was exceeding the permitted length for a shell command.
I am not sure the issue with you is same or not but u can check that or you can change your script from shell to perl in case it is shell.
From my Tcl script, I would like to find the path to the tclsh executable which is running my script (like sys.executable in Python), or at least find how the tclsh was invoked from the command line (like $^X in Perl)?
Just found it by myself: It's
info nameofexecutable
I'm new to Lua and work around with some tutorials, try some basic stuff like coding common algorithms etc.
But I have some trouble while using the lua interpreter on my mac os machine.
For example let's say we have a file called 'sample.lua', holds the code line:
function fib(n) return n<2 and n or fib(n-1)+fib(n-2) end
How do I run that function from terminal?
If I don't use any function, I just call the script with 'lua script.lua' - works!
Next question points on the basic understanding between the usage of non-compiled and compiled lua-source. Why is lua code run without compiling, like I mentioned before (lua script.lua)? Or will this statement compile the code temporarily and run afterwards?
Thanks in advance

You can run lua from the terminal with the -i flag:
lua -i luascript.lua
This will execute the script and then put the interpreter into interactive mode. Then you could call the function right from the interactive prompt:
fib(3)
To run that function from the terminal, you would have to do something like:
lua -e"dofile'sample.lua' print(fib(3))"
The -e there just tells it to execute the following string, which loads your file 'sample.lua' and then prints the result of fib(3) to stdout.
I don't know the answer to your second question though.
Lua scripts are always compiled into Lua VM instructions before running. Precompiled scripts just skip this step.
Pretty self explanitory this one.
As described here: http://wiki.hudson-ci.org/display/HUDSON/Hudson+Script+Console you can access the Groovy script console from the Hudson web interface. I want to be able to access this from a shell so I can execute Groovy scripts from a terminal etc...
Any ideas?
Download http://server/jnlpJars/hudson-cli.jar
Use java -jar hudson-cli.jar -s http://server:8080/ groovysh for interactive groovy, java -jar hudson-cli.jar -s http://server:8080/ groovy to run a script.
