shell;scripting
As mentioned in the comments the symbols can mostly be found by looking in man sh and searching for those characters.  Here's a summary:$* expands to the command line parameters passed to the script\ escapes the next character from interpretation by the shell, in these cases, it continues the current command line to the next line.|| is the shell or operator.  The command after the || will be executed only if the command before the || failed.eval Concatenate all the arguments with spaces.  Then re-parse and execute the command.  It appears to have no reason to be in this script.\  Actually not related to each other. The quote terminates the preceding literal string, the backslash continues the command to the next line.Please consult man sh for more details and proper usage of these features.
