Simple cases of ',' and ' ' require extra complexity to work around an Which sends the complexity through the roof, and even the supposedly Require that each possible location be handled as a special case, Note: the third example has been omitted for two reasons: the '=' case The following examples, these are illustrated in that order. Split the string into elements and intersperse them with flags. Some extra flag argument to indicate that it should be inserted, or to Only ways are to assume it, and add it back in unconditionally to use If it is important to pass a delimiter, usually the '=' character, the Quote marks, or without any) results in the same display When invoked with "this that", "this=that" etc. ![]() The earliest argument and the closing quote mark is part of the last Of knowing if it was a space, a a tab, a comma, a semicolon, or anĮquals sign) - quotes don't help: the opening quote mark is part of Information about the nature of the delimiter is lost (you have no way When a delimiter isĮncountered, the argument is split into two arguments, and all This is extremely useful in recursive and reentrant batch offĬommand line arguments can be used to pass any string that doesn'tĬontain a delimiter into the batch file. Given in long form, the name is preceded by the path that was used. If given in short form, it is just the name if %0 always exists (initially) and is the name of the batch file as Of the %0 - %9 range, an argument cannot be recovered. Value of the one to its right on the command line. For each SHIFT, %0 disappears, and each argument takes on the ![]() %0 through %9 are readily available, andĪny beyond %9 can be read by SHIFTing them down into the single digit ![]() Only and are referred to by an escaped digit ('%' is the escapeĬharacter in batch files). Allīut ERRORLEVEL, which is of type "byte", are of type "string".Ĭommand line arguments are the strings following the program name in There are four kinds of variables in batch files: command lineĪrguments, environment variables, ERRORLEVELs, and FOR variables.
