Cron Script Question

A co-worker is having trouble w/ a job scheduled from cron and I got involved. Unfortunately I couldn't seem to find the answer and need some help. First off, I'm pretty sure he's using redhat linux. Anyway, I want to schedule a cronjob to run a java class. Let's say that, logged in as root, I excute the java class like this...

java MyJavaClass > MyJavaClass.out

This works and the file MyJavaClass.out ALWAYS contains data. In cron I created this entry below to run this command at 5:30AM each day)...

30 5 * * * java MyJavaClass > MyJavaClass.out

HOWEVER, when cron kicks off the job the size of MyJavaClass.out is always 0 bytes. So it looks like the job kicked off at the right time but, for some reason, the call to "java MyJavaClass" didn't execute correctly. My gut feeling is that this is some weird scripting error where the pathing isn't set correctly inside this cron script but I can't figure it out. I've even tried putting in the full path name to the java command (/usr/bin/java or whatever it was) but it still comes back w/ zero bytes. Can anyone explain what's going on to me? Thanks in advance!

There is this script I'd like to put into cron, but it asks for date verification. It'll prompt you to press enter to continue. Usually, 100% of the time the dates are ok, so is there a way to run this script in cron and bypass the "enter" prompt? (3 Replies)

GIT-CHECK-ATTR(1)						    Git Manual							 GIT-CHECK-ATTR(1)

NAME
git-check-attr - Display gitattributes information SYNOPSIS
git check-attr [-a | --all | attr...] [--] pathname... git check-attr --stdin [-z] [-a | --all | attr...] DESCRIPTION
For every pathname, this command will list if each attribute is unspecified, set, or unset as a gitattribute on that pathname. OPTIONS
-a, --all List all attributes that are associated with the specified paths. If this option is used, then unspecified attributes will not be included in the output. --cached Consider .gitattributes in the index only, ignoring the working tree. --stdin Read pathnames from the standard input, one per line, instead of from the command-line. -z The output format is modified to be machine-parseable. If --stdin is also given, input paths are separated with a NUL character instead of a linefeed character. -- Interpret all preceding arguments as attributes and all following arguments as path names. If none of --stdin, --all, or -- is used, the first argument will be treated as an attribute and the rest of the arguments as pathnames. OUTPUT
The output is of the form: <path> COLON SP <attribute> COLON SP <info> LF unless -z is in effect, in which case NUL is used as delimiter: <path> NUL <attribute> NUL <info> NUL <path> is the path of a file being queried, <attribute> is an attribute being queried and <info> can be either: unspecified when the attribute is not defined for the path. unset when the attribute is defined as false. set when the attribute is defined as true. <value> when a value has been assigned to the attribute. Buffering happens as documented under the GIT_FLUSH option in git(1). The caller is responsible for avoiding deadlocks caused by overfilling an input buffer or reading from an empty output buffer. EXAMPLES
In the examples, the following .gitattributes file is used: *.java diff=java -crlf myAttr NoMyAttr.java !myAttr README caveat=unspecified o Listing a single attribute: $ git check-attr diff org/example/MyClass.java org/example/MyClass.java: diff: java o Listing multiple attributes for a file: $ git check-attr crlf diff myAttr -- org/example/MyClass.java org/example/MyClass.java: crlf: unset org/example/MyClass.java: diff: java org/example/MyClass.java: myAttr: set o Listing all attributes for a file: $ git check-attr --all -- org/example/MyClass.java org/example/MyClass.java: diff: java org/example/MyClass.java: myAttr: set o Listing an attribute for multiple files: $ git check-attr myAttr -- org/example/MyClass.java org/example/NoMyAttr.java org/example/MyClass.java: myAttr: set org/example/NoMyAttr.java: myAttr: unspecified o Not all values are equally unambiguous: $ git check-attr caveat README README: caveat: unspecified SEE ALSO
gitattributes(5). GIT
Part of the git(1) suite Git 2.17.1 10/05/2018 GIT-CHECK-ATTR(1)
