From 71bdd87f58f6791e50ddd7a078c47f9803c523ee Mon Sep 17 00:00:00 2001 From: Alexander Kapshuk Date: Thu, 31 May 2018 22:22:47 +0300 Subject: ver_linux: Do not check for ver_linux pattern in version function Checking whether output of commands matches the ver_linux pattern in the version function is original shell implementation legacy code. When the original implementation failed to locate a particular utility, it generated error output along the lines of: ver_linux:line number: command not found. The awk implementation, does not contain the name of the script within the body of the error message returned by the subshell when a given utility fails to be located. The error message returned is along the lines of: sh: name of utility: command not found Safeguarding against the ver_linux pattern being found in the output being parsed may thus be safely omitted.
