Description
The executable search path (typically the PATH environment variable) contains a list of directories for the shell to search to find executables. If this path includes the current working directory or other relative paths, executables in these directories may be executed instead of system commands. This variable is formatted as a colon-separated list of directories. If there is an empty entry, such as a leading or trailing colon, or two consecutive colons, this is interpreted as the current working directory. Paths starting with a slash (/) are absolute paths.

Check Text ( C-42484r1_chk )
Check the global initialization files' executable search paths. Procedure: # grep PATH /etc/bash.bashrc /etc/csh.cshrc /etc/csh.login /etc/environment /etc/ksh.kshrc /etc/profile /etc/profile.d/* /etc/zshrc This variable is formatted as a colon-separated list of directories. If there is an empty entry, such as a leading or trailing colon, or two consecutive colons, this is a finding. If an entry begins with a character other than a slash (/) this is a relative path, this is a finding.
