New Revision: 391518

URL: http://svn.apache.org/viewcvs?rev=391518&view=rev
Log:
Added for more generic support of 'which' functionality
by supporting it locally instead of assuming it is either
in PATH or a shell built-in function.

Added:
    incubator/harmony/enhanced/trunk/sandbox/contribs/bootjvm/bootJVM/support/which.sh   (with props)

+# @brief Generic replacement for <b><code>which</code></b>
+#
+# This script include file contains the logic needed
+# to derive proper functionality of shell command
+# <b><code>which</code></b> for systems that do not have it.
+# This is useful in shell scripts that need to locate where
+# an executable program of script is found in the PATH environment
+# variable, an operation typically performed by either the shell
+# built-in function, the executable shell script, or the binaray
+# program <b><code>which</code></b>.  It should work on any flavor
+# of BASH, Korn, and Bourne shells.  A stand-alone invocation does
+# nothing, but is benign.
+#
+# Loaded where needed as:  <b><code>. support/which.sh</code></b>
+#
+# Invoke from a shell script as:
+#<b><code>VARNAME=`which pgmname`</code></b>
