QUESTION
I need to automatically execute some perl scripts from Java. I use Runtime.getRuntime().exec
to start the perl process. I generate a start-parameter-string and pass it as an argument to exec. The String looks somewhat like this:
cmd /C start /wait perl "path\to\perl\script" -p1 scriptparameter1 -p2 scriptparameter2
I also tried
perl "path\to\perl\script" -p1 scriptparameter1 -p2 scriptparameter2
.
If I copy that String and execute it via Windows+R everything works, but via exec the Perl-scripts can't find the svn-command. Why does it make a difference if I execute the perl process from java instead of directly from windows?

Answered 2019-Jun-28 at 14:20Date::Calc has an XS component Date::Calc::XS, i.e. it needs to compile some C code. When you upgrade Perl, you need to recompile all the XS modules so they work with the new Perl version. The installed package is linked against a library that doesn't exist anymore (which is what the System Error window tells you).
Reinstalling Date::Calc should fix the issue, but make sure all other XS modules are updated, too.
QUESTION
I'm having a Bash-Script that sequentially runs some Perl-Scripts which are read from a file. These scripts require the press of Enter to continue.
Strangely when I run the script it's never waiting for the input but just continues. I assume something in the Bash-Script is interpreted as an Enter or some other Key-Press and makes the Perl continue.
I'm sure there is a solution out there but don't really know what to look for.
My Bash has this while-Loop which iterates through the list of Perl-Scripts (which is listed in seqfile
)
